> it seems to be on of HN's favorite biology topics
Yeah, it seems HN knows more about phages than physicians, which is pretty bloody damning. Why TF don't physicians know about this?
"First, Strathdee found an obscure treatment that offered a glimmer of hope -- fighting superbugs with phages, viruses created by nature to eat bacteria."
According to TFA, Strathdee is also an infectious disease epidemiologist, and she didn't find out about phages until her husband had almost karked it, after several months of fighting an antibiotic-resistant infection.
There was a similar story on HN three years ago about a teenager in the UK with cystic fibrosis and an antibiotic-resistant infection after a lung transplant. The physicians treating her didn't know about phages, and her mother had to suggest it. [https://news.ycombinator.com/item?id=19863445]
So that's at least two cases of people dying slowly from antibiotic-resistant infection until someone suggested phages, which were then successfully used to save their lives. Are the treating physicians incompetent?

It's not a standard therapy - she had to go to extremely specific specialists, including USAMRID. I've seen her talk multiple times, and am a great admirer of hers, but phage as they are are very much last ditch, bespoke treatments.
Specialist ID physicians know - there's whole sessions about it at major infectious disease conferences. But there's a huge gap between "Knowing" and "Have the capability to use this in practice".

Also, because I had a sneaking suspicion - Strathdee was an HIV researcher. In fairness, most of infectious disease epidemiology is HIV research.
It's entirely reasonable she wouldn't have necessarily heard of a fairly niche therapy in another area - phage is basically a non-starter for global health (where her work was), and hospital epidemiology is a very niche field.

That is not a good excuse for not knowing something infectious-disease-related that the average user on a software engineering forum seems to know. It's like MDs talking about a programmer and saying something like 'It's entirely reasonable that, as a Python dev, he wouldn't have heard of compilers. He doesn't need them for his work, and compiler developmentn is a very niche field'. That's simply not a good excuse.
I'd suggest its much more like, as a Python dev, not being up on the latest applications of Rust for HPC.
If phages are so extremely niche as you suggest, then how come that they seem to be common knowledge among software engineers?
And you're making an inconsistent comparison: it's not about being an expert, not even about having read a wikipedia article on the topic, it's merely about having heard of that thing existing. A Python dev who has never even heard of Rust or can't even guess what HPC might stand for would be strange indeed. And the same goes for medical professionals who haven't even heard about a whole class of treatment options for a serious global disease problem (and, as a corollary, cannot recommend consulting a specialist).

Of course we learn about bacteriophages in medical school and university. I’m a radiologist and even I know about it. It’s just not FDA approved treatment. You’re talking about inoculating someone with a virus intentionally
Thanks for your insights here — is there any innovation going currently wrt phages either in academia or the startup world that looks significant from a practical point of view? I've also seen people claim that phages were never researched as much in the West because they were popular with the Soviets and therefore had a kind of tainted PR image, is there any truth to this or was their lack of prevalence primarily due to more serious issues?
Answering in reverse order:
Phages were used in the west prior to the advent of antibiotics. They had a repetitional issue then, because our purification methods weren't always great, so phage preparations had both phage and potentially bits of the cell wall of the bacteria they had killed. Bacterial cell walls contain endotoxins, which are potentially quite dangerous.
They were largely abandoned in the West because with the advent of antibiotics, a wildly more effective solution to bacterial infections was present. The Cold War meant the Soviet Union had less access, and so needed to continue working on phage research more intensively.
There's a lot of work on phages going on in academia - I don't know about the startup world, TBH. I think some of the most promising leads are in combination therapy. It appears that treating with phage can push bacteria back into susceptibility (basically, two selective pressures at the same time), which is a cool idea. But the gap phage has to jump from "Interesting bespoke one-time treatments" to a generalizable treatment is a pretty big one. My expectation at least in the medium term is they'll be supplemental treatments for a few well known conditions where you can maintain phage libraries for them.

How big is a 'library', and do you need to 'tune' - why not mix a dash of each phage type and inject the mix?
(I know nothing about this)
(I know nothing about this)
A library is potentially quite large - essentially, you need a phage that's for that particular organism. Potentially a large number of each species, given that phage and bacteria are in an evolutionary arms race.
The trickier part is you have to keep them active and functional over long periods. That's not something most hospital labs are equipped to deal with.

Thanks for sharing. Multiresistant bacteria are high on my list of slow-mo crashes happening before our eyes that no one seems to be talking about (compared to eg climate change, which is also a slow-mo catastrophe, but at least one that people are talking about). And it's always puzzled me how little I hear about work being done on phages, which pose an interesting approach to tackle the problem (compared to eg quantum computing, where commercialization potential seems to be a lot further out).
At least in France, a series of antibiotics are not allowed to be used/sold outside of hospitals. This is to ensure that hospitals have some last resort antibiotics in hard cases. But even with that, they have issues.
In Germany, where I live at the moment, the risks and issues are well known and talked about. I have seen a large reduction of the prescription of antibiotics. The younger the MD, the less antibiotics are given.
But 80% (maybe even more) of the antibiotics are used by animal farming...

This is what needs to be talked about more. Like guns in the US, or telecom oligopolies in Canada, it seems animal based agriculture gets the “thoughts and prayers” treatment rather than any substantive discussion about what harm it is causing the planet, human health, and biological safety via antibiotic resistance.

The FDA already banned human antibiotic use in farm animals except to actually treat infections.
The ban was a few years ago.

1ml of sea water will contain billions of phages, but its pot luck if you get the right strain.
Another thing not mentioned with antibiotics is man y are penicillin based that when metabolised become penicillamine which is used to treat copper toxicity or Wilson's disease, ie it makes the liver dump copper out of the body. Copper is needed to produce Interleukin-2, a naturally occurring chemo drug, most effective when injected into tumours, but having naturally high levels circulating can be helpful as a prevention measure.
Creatine when metabolised becomes creatinine which in sufficient qty can kill gram positive and gram negative bacteria. If you get 3rd degree burns, the muscles catabolise to release creatine and then the creatinine helps to keep bacteria at bay with the wounds.
It probably also explains why the US military are reportedly the only one's to use copper sulphate to debride battlefield wounds. Even the WHO dont recommend using it! Copper sulphate will dissolve skin though.
Vitamin D also increases creatinine, and because creatinine is used for estimated glomular filtration rate kidney tests, high levels of creatinine can make you appear to have various stages of kidney disease. Medical lab tests (human and veterinary) can not tell if you are supplementing so dont get an inaccurate diagnosis.

It kind of worries me when people talk about reduction in prescription of antibiotics. If we are talking about primarily about false diagnoses and prescription of antibiotics when there exist equal or better treatment plans, then a reduction in antibiotics is good. The day when people got antibiotics in order to treat a cold is hopefully over.
The cases that worries me most is however debilitating chronic illnesses (where antibiotics is used as a stop gap until medical science find a cure), and illnesses which if let untreated might turn into a debilitating chronic problem. I hope they are keeping a close watch on the outcomes from those younger MDs.
Antibiotics in animal farming is obviously terrible. Animals should not be allowed to be kept unless it is in an environment that is safe and healthy for them. Antibiotics is a tool used to fix how poor some large scale farmers treat their animals.

Many doctors don't bother to test if the infection is bacterial or viral or fungal (outside of covid, flu, rsv, and some others). My wife had an outer ear infection. The doctor confirmed it was an outer ear infection, then prescribed antibiotic drops. They didn't do any test. It could be bacterial or it could be fungal. If fungal, the antibiotics will actually make it worse.
So my wife uses the drops for several days and gets worse. What's the solution? Mix half distilled white vinegar (5% concentration) and half 91% isopropyl alcohol (or 190 proof ethanol). This is a cheap solution which is generally effective for both fungal and bacterial outer ear infections. She was better in less than week.

Over 90% of outer ear infection is caused by bacterial infection, with 10% being fungal (and then, those are more liekly in tropical environments). The risk of fungal infection in non-tropical environments is thus fairly low probability.
There has also been several (4 that I can find myself) studies done on using acidic drops as the only treatment for ear infections, all which has shown them non-effective to clear an infection. Alcohol can also irritate the skin further, increasing inflammation.
Ear infections are however complex since most of the studies are either done on children, commercial or military divers. The military protocol in the Netherlands is to start with an acidic solution and then if the inflammation get worse introduce steroids. If that doesn't clear it, then add a combination of antibiotics and steroids. Steroids has the problem of increasing risk to bacterial infection, but the combination of using antibiotics with the steroids reduces that risk. It is this combination that doctors use in post surgery.
The Dutch protocol seems like the optimal treatment protocol for now, but it assumes you got a doctor to monitor it. My guess is that regular doctors jumps to the last step with the assumption that it is bacterial infection in order to minimize the need for further visits. One study I read also mentioned that adherence to correct application of the drops was one of the most significant factor in outcomes, which might imply an other reason to go for the strongest treatment first.
One thing that favors alcohol however is that keeping the ear dry is extremely important in addressing outer ear infection and preventing bacteria from growing. The theory behind vinegar and alcohol does thus seem quite sound from a theory perspective, stopping the bacterial infection before it get a chance to grow.

The US military does, or at least used to, use the alcohol/acid drops prophylactically - whenever you'd get out of the water you'd put some drops in.
It's interesting that the studies show that solution as ineffective. It cured my wife. Then someone at work had an outer ear infection that recurred after two treatments with antibiotic drops. This solution also solved their problem.
As a side note, my wife was on steroids when she contracted the infection. So I think that contributed to her catching it.

I am not aware of any study on prophylactically use, but I am cautiously hopefully that it work based on personal experience and from what I hear. For water sport activities, flushing with clean fresh water, dry it, and then spraying an acid solution seems to give some defense in keeping outer ear infections at bay. Alcohol could help drying it out, through because of the risk of triggering inflammation in the middle ear I personally avoid it.
I don't know why the studies shows them to be ineffective. Since they include acid drops in the studies it seems to be a well known home remedy, and given that it used prophylactically by the military in several countries there seems to be some reason for it. I could make a guess that doctors in the military/pediatric care are already keeping the ear of the patient dry so that alcohol don't provide any additional benefits, and they remove vax/debri in case those prevent the ear from drying.

Sounds like you and the AMA have never had the misfortune of living in a city with tons of indoor mold.
+1 on the alcohol/vinegar. If you've had one of these outer ear infections you'll remember what it felt like early on, so you're probably able to tell when it feels like you might be getting another one. Start using the alcohol/vinegar mixture immediately, and you might avoid the infection altogether.
If you've never had one of these - you do not want to get one. They can be extremely painful.

Wouldn't it be better to use them separately?
I remember from high school organic chemistry that an acid combined with a base yields a water and a salt, but and acid combined with an alcohol yields a water and an ester.
https://en.m.wikipedia.org/wiki/Ester
"Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product."

Esters tend to evaporate quickly, right? That's part of the benefit of the drops is to dry the ear out. I haven't heard of them being applied separately. I would be a little careful since applying them separately means increasing the strength of the acid and alcohol.
iirc antibiotics in cows are not principally used as medicine. it's because chronic antibiotic use makes cows put on weight faster. I don't know the mechanism.
It would be interesting to know of this mechanism has any effect in humans, being that humans are eating more meat that's been treated with antibiotics and were also gaining weight at rapid levels at society wide levels.
I'm curious also. Could it be that antibiotic meats affect the gut / microbiome? Perhaps creating an environment favorable to certain gut bacteria that lead to increased appetite or fat?
Similar recollection here. So, obvious question - would it work to standardize on giving the cows some old, seldom-useful-in-human-medicine antibiotic? If yes, that would seem to minimize the resulting harm to human health...
If these older antibiotics would stop being used, they could eventually be used on humans again. Maintaining chemical defenses is an evolutionary disadvantage compared to populations without them if the antibioticum is not present in the environment anymore.
> The cases that worries me most is however debilitating chronic illnesses (where antibiotics is used as a stop gap until medical science find a cure)
Which debilitating, non-bacterial chronic illnesses are treated with antibiotics as a stopgap measure?
Which debilitating, non-bacterial chronic illnesses are treated with antibiotics as a stopgap measure?
Controversially but famously, "chronic Lyme disease" involves course of multiple super strong antibiotics over potentially years. Then things to try to save your organs from antibiotics. Then pills to help you digest those. Taking 50 pills on regular basis is apparently common enough.
Any non-treatble illness that causes a buildup/environment for bacteria that trigger debilitating symptoms.
The human body has many defenses and mechanics to keep bacteria in balance. I would point particularly towards the gut/intestant, the skin, ears, anus, bladder and genitalia for places where bacteria need to be constatly kept at the correct balance. Some things are treatable. Some things are possible to cut off. Some things are less known/fixable, in which case symptoms is the only thing possible to addressed at this time.

acne is bacterial but chronic. it's standard practice for dermatologists to prescribe long-term antibiotics for severe acne, rather than turn to accutane.
not necessarily debilitating, but current treatments for rosacea include a low dose prescription of antibiotics like doxycycline, basically forever.
I have rosacea and it of course goes up and down. used tgel for a while then decided to only apply it to my right side of face. After a ~year there was never ever difference between two sides of my face, they went up and down together depending on temperature, environment, sweat, stress, food, etc. My doctor could not believe that I would try that, but it seemed a super simple way to check if all those antibiotics actually Did anything. For me at least they didn't.
Antibiotics are given to animals to promote growth, not (just) treat disease.
When livestock get sick, they are “culled,” not treated.
Which makes the use of antibiotics (“growth promoting anti-microbials”) all that more outrageous.

Depends on the economic value of the livestock. For example, a milk cow is probably economically worth being treated. Even if there are regulations that ban selling their milk, they can still be used for breeding.
I have a collection of antibiotic prescriptions that were routinely given to my kids at the public clinic (South American country here) at the smallest sign of a sore throat or some other infection. I didn't give them the antibiotics and my kids got well after a few days (they did take antibiotics whenever it was more serious). At the other end of the aisle, I have friends who will switch doctors if they don't prescribe their kids an antibiotic whenever there's a simple sore throat. A lot of doctors here will prescribe them right and left, just to be safe from any later criticism of not giving their patients enough medication. Oh, and I never had a doctor here ask for a test to see wether a throat infection was viral or bacterial.

These measures that disallow use of antibiotics by humans are inhumane.
For example, a chart in the article below shows huge growth in number of admissions after 2002 guidelines to replace full antibiotic therapy for acute UTI with 3-day antibiotic treatment.

There are plenty of people/companies working on phage therapies, and there are clinical trials happening now [1]. In some eastern European countries you can buy phage solutions over the counter. It just doesn't get much press - though I'd speculate that's because phage therapy clinical trials have been pretty lackluster so far.

What an amazing story, one which should give hope to the many people that are battling superbugs as we speak. Her (Strathdee's) Wikipedia page gives some more background, out of which this stood out to me:
"Although phage therapy had been used for one hundred years in Eastern Europe, it was not licensed for clinical use in the United States or most of Western Europe" [0]
Which indicates (if not proves) that healthcare is one one of the casualties of our polarized world.

It's not really that.
Eastern Europe had to continue with phage therapies because they didn't have great access to antibiotics, which have many superior properties. Phage was used in the Western world, but early versions had serious purification issues, where people were getting killed by bacterial endotoxins present in the solutions.
It's not really "lost" as much as a readily obvious alternative was present in one setting and not the other.

This is a very bubble centric view of the history. Eastern bloc countries, notably East Germany, Hungary and Yugoslavia, had very active and thriving drug research and manufacturing sectors. The Soviet Union, whilst having the drug research and manufacturing of their own, was purchasing swaths of drugs from the three aforementioned countries.
Azithromycin, one of the most widely prescribed macrolide antibiotics in the US today, was, in fact, discovered in Yugoslavia and licenced to Pfizer in 1980s.
Phage therapy was considered a novel area of research in a few of the Eastern bloc countries, but it never became neither widespread nor a substitute for antibiotics. It was just as fringe in those countries as it was elsewhere.

it's really terrible how the caring for one's health aspect of the medicine industry has taken a secondary role, the really important thing is corporate profit, patients are getting treated, but not healed
this is not to say the treatments are not effective, but I think it's telling to consider that the reason treatments remain effective is to avoid defrauding customers (err. patients), not becuase the intention is healing people.

Research in the field of phage therapy has traditionally been strong in the Soviet Union since the 1920s and in other Eastern Bloc countries such as the GDR after WW2. In recent years, the area has gained renewed attention in Germany. There exists currently an extensive programme of basic research on phages funded by the German Research Foundation (DFG). The project Web-site is located at: https://spp2330.de/
Broad Spectrum Antibiotics were superior to Phage Therapy when they were first introduced, as they didn't necessitate time intensive cultivation of the pathogen prior to administration. The high selectivity of Bacteriophages was their main disadvantage. Today, with all the knowledge about the importance of a healty gut Biome, the potential risk to "good bacteria" has to be weighed before administration of antibiotics is considered. Fast diagnostic tests, like the use of PCR to detect Covid-19, turn Phage Therapies greatest Drawback, its selectivity, into its greatest advantage.
Shout out to the country of Georgia for being the stronghold of this since the 1920s [1]

Great story and glad about the positive outcome. But also highlights the benefits of being well connected. Doubtful a couple in a similar situation that were not a professor and associate dean at a well known university could've obtained the same outcome.
Yes, I had the same reaction. Altogether it's inspiring and I'm happy to see novel treatments like it when antibacterial therapies are desperately needed. At the same time seeing these inequities in the system was disturbing to me.

Anyone with an aggressive bacteriological infection should be aware of and consider phage therapy when beginning treatment.
It is also important to pre-treat the selected phage in a concentrated solution of the pathogen to allow time for adaptation prior to injection.

It wasn't a miracle. It was extreme privilege. She had elite access and got extraordinarily special treatment and response at every step. The phage aspect is very interesting, I've been reading about phages on HN for over a decade probably (and in that time there has seemingly been relatively little progress in their usage in the West). The rest of the story is rather disgusting in how it's portrayed in the article vs what's actually going on (connections, status, privileged treatment). Oh but it was like a miracle - no, no it wasn't.

Wow.
It has little to do with her having "extreme privilege" or "elite access" and a lot to do with her being an infectious disease specialist and knowing who to reach out to for help. This is literally what people on HN do all the time. But apparently when someone outside of "tech" takes advantage of their industry connections, it's "extreme privilege" rather than just being smart.
It's so hypocritical to see these kinds of comments about "privilege" being posted to a forum where so many people don't grasp the kind of privilege they have that so casually lets them judge others. (Or do you make comments like this when HNers offer to help other HNers with their job hunts, or when complaints about Google, etc., reach the front page and something actually happens to get the situation resolved?)

I hope your point is that access to this shouldn't be restricted to such privileged people. The legal and regulatory barriers could be lifted, and if that happened then companies could be started to provide the therapy.
I got this from the article too. This couple was incredibly connected.
But.. they lived and worked in a field for 40 odd years, why the hell couldn't they take advantage of it? This isn't like Dad getting his frat bro son a job at Goldman.

So if he had received the phage treatment sooner, would that have lessened these effects? Or are they sure that these effects were not caused by the phages themselves? Obviously it's better to be alive, even with these effects, but if doctors were choosing between several options for a future patient, they'd presumably want to know the causal chain.

Yes getting the treatment sooner would’ve prevented damage, though how much would be harder to say. According to the account, by the time of treatment the bacterium had caused widespread damage and the patient had multiple organ failure before the treatment.
Phages are also highly adapted to attack bacteria and often specific bacteria. It’s highly unlikely to affect humans. That’s easy to show since dirt is loaded with bacterial phages.
Additionally there was significant research in Soviet bloc on the safety and efficacy of phage treatment.
I’m hoping phage treatment becomes more common and better. The rise of bacterial superbugs is one of the greatest threats to modern life, as in we don’t expect ourselves or loved ones to die routinely from bacterial infections. However that’s very recent thing in human history. I’d readily wager that bacterial diseases have killed far more people than viral infections. They’re the literal plague.

There are two really interesting parts of Russian medicine which the West hasn't really pursued which it should. Phages is one and they really are an incredible solution to antibiotic immune bacteria, the issue is always finding the right one, there are so many different phages and bank of all of them would be enormous, 10s probably 100s of thousands.
The second is auto vaccines and Lysates which present dead bacteria to the body so it can create an appropriate immune response. They are used in Russia for things like Urinary tract Infections which in the West are often untreatable with antibiotics but they do seem to work. Get the immune system to recognise the baddy and work out how to kill it and then in the harder to reach places it can be effective. Works fairly well for Chronic infections but the issue is identifying the bacteria precisely to match and existing mix or collecting the bacteria and cultivating and killing it mechanically or with heat so it can be injected back into the patient safely in other places in the body.
Both techniques were outrun by antibiotics in the beginning, antibiotics are a lot easier to administer as you don't have to identify the pathogen precisely and its easy to make in bulk. But both these more natural solutions are a lot harder for bacteria to become immune to and have undergone the evolutionary process alongside us and them. I think both are worth serious efforts and development.

Ideally, the bacteria can't become immune.
The virus evolves and adapts with the bacteria, modifying its receptors and modes of action as the host survivors mutate, which is beyond the capability of a chemical antibiotic.
This is why it is so important to pre-treat the phage in a concentrated solution of the target pathogen prior to injection into a patient, which allows the virus to maximize infectivity.

It seems that’d help make semi “broad spectrum” possible as well.
Manufacture a serum loaded with hundreds or thousands of phages known to target superbugs and let them decimate the bacteria. Choose the survivors. If you could automate the last step it could be something any old doctors office could do.

It is important to carefully match the phage with the target pathogen. A mismatched phage will not be effective.
This tool can't be used like antibiotics. It requires expertise in classification.

Why don't we use machine learning to find phages?
What makes you think we don't?
Machine learning isn’t great at everything. Is “finding phages” one of the tasks it good at.
I remember when Google was claiming they could track the Flu based on searches, it was going to revolutionize tracking pandemics.

There's a decent amount of work being done, broadly, in using machine learning to identify resistance mechanisms and work in antibiotic discovery. There's likely applications there for phage as well. But the real problems holding phage back is not finding them (they're trivial to find in the wild) but operationalizing them.
For me, the most foreseeable application of ML to phage work is predictive models of antibiotic treatment failure.

Why do we keep reading annoyingly insular case reports of people with relatively common, but highly multi drug resistant bacteria who get saved by phages, while at the same time being afraid of the antibiotic apocalypse?
What keeps us from having a register/bank of highly effective phages to treat people with those boring old multi drug resistant bacteria bacteria?
Why do we keep saving and at the same time ruining peoples lifes with fluoroquinolones, gentamicin and other dangerous antibiotics instead of just giving them phages?

It's super complicated - clinical trials of phage therapy have been relatively unsuccessful for one thing, so there's that. But additionally:
- Bacteria adapt to phage infections, just as they do to antibiotics
- Many phages are very host-specific, so a given cocktail might not even be able to target the pathogenic bacteria in question. There are phages with broader host spectra, but then they might be able to target the rest of your microbiome, which can lead to other health problems
- Since phages have protein shells, human antibodies will target them, and may prevent them from reaching the infected tissue. You might also only be able to use a particular phage once for this reason.

I listened to the audiobook for 'The Perfect Predator' (https://www.audible.com/pd/The-Perfect-Predator-Audiobook/15...) ... was a good story and amazing he survived with so few long term complications. They were certainly well connected, but he also was very resilient being able to recover from (if memory serves) multiple rounds of sepsis & organ failure.
It’s amazing and very heartening that they were able to get the FDA on board in a matter of weeks.

Very interesting - thanks for sharing. I'm not a scientist and the only time I've come across discussion of phages before was in the Michael Crichton novel, Prey.
In a nutshell, it works but antibiotics work better (until they don't, eh?), so phage therapy was largely eclipsed in the West. However:
> Isolated from Western advances in antibiotic production in the 1940s, Russian scientists continued to develop already successful phage therapy to treat the wounds of soldiers in field hospitals. During World War II, the Soviet Union used bacteriophages to treat many soldiers infected with various bacterial diseases e.g. dysentery and gangrene.[28] Russian researchers continued to develop and to refine their treatments and to publish their research and results. However, due to the scientific barriers of the Cold War, this knowledge was not translated and did not proliferate across the world.

I would hazard a guess that the reasons are other than translation. Keen scientists learn enough of foreign languages to read papers in their area of interest - reading scientific language in a speciality area is much easier than learning a language generally (I personally know scientists that have self-taught themselves for Russian, German, French, etcetera).

> across the world.
Is that an American centric worldview? It makes little sense. Maybe the USA and allies, but there is a lot more to the world than that, and phages haven’t been used. The reasons for that are very unlikely to be due to what appears to be a simplistic world view.

I gather phage therapy was seen in Western bloc nations as akin to Lamarckian evolution, so even otherwise keen scientists tended to dismiss it. And of course, antibiotics work really well (until they don't.)
I have no idea how widespread phage therapy was in the Soviet bloc nations.
The Cold War distorted a lot of things.

That Wikipedia entry mentions that bacteria may develop immunity from previous bacteriophage infection.
One of the more interesting studies I saw at IDWeek a year or two ago was phage/antibiotic combination therapy, which improves both. Basically, the bacteria being able to out evolve both of them at the same time is substantially reduced, and the introduction of phage can improve a bacteria's susceptibility to antibiotics.
Cool approach
Bacteriophages are also in Arrowsmith by Sinclair Lewis, where they were used to treat plague.
Interesting topic aside, thank you so much for linking to the lite version.

In Australia, we're starting a new clinical trial (phageaustralia.org) for phage therapy, funded by the Australian Medical Research Future Fund: https://www.health.gov.au/initiatives-and-programs/medical-r...
We're just gearing up with a team distributed across Aus that tackles the clinical, biology and data/engineering side (this is my job).
This clinical trial is a bit different from trad drug discovery, since this clinical trial assesses the entire PROCESS of: (1) sourcing the phage (2) testing the phage's effectiveness against a patient's bacteria (3) manufacturing the phage to be safe for the patient/indication. We're not trialling a phage itself, like most active phage therapy clinical trials out there right now.
We're emphasizing the "therapy" aspect, of collecting data on the phage, bacteria, and measuring immune reaction in the patient to figure out what works, what doesn't work, and most importantly safety.
Phages are interesting because we can "train" them to work specifically for each patient's infection, and this is much more complex than just throwing antibiotics at a wall. In essence, effective and large scale phage therapy is a data problem — we need to figure out why a phage works (or doesn't work) for a specific bacteria and indication first. (How will a phage respond to pseudomonas in the lungs? How will it work in the gut? On the skin? etc.). We also need to know what phages will work in combination with antibiotics, because most doctors will want to keep using antibiotics.
But ideally, we want to be able to predict what phages will work in a patient, so we can just prep and manufacture those ahead of time, and have some amount of certainty that given our data this will work.
There are tons of phage therapy clinical trials going on, including from places like UCSD, Mayo Clinic in the US, in Portugal, Israel, Belgium. Most of these aren't trialling the process itself like Phage Australia though — they're trialling the phage itself, or a combination (a phage cocktail)... And there's more countries like Canada and the UK getting interested in it as well.

I have a deep and abiding fondness for phage, but they're not quite as awesome as they seem at first glance. From the perspective of an infectious disease epidemiologist who has been super-interested in phage for my whole career (literally tried to get a job out of undergrad with a phage therapeutics startup):
1) There's no such thing as a "broad spectrum" phage. They're organism specific, and that means not only would you need to keep a phage library on hand, but you'd have to do a lot of diagnostic tests. That's going to be both expensive and tricky. There are treatment guidelines for things like sepsis right now that are basically un-doable with phage therapy because of the time it takes to tune a phage library.
2) Phages are living things. Not only is that a weird regulatory framework to be in for a drug, but it also means that you need to be able to keep phage alive. In contrast, antibiotics are inert.
3) Phage therapy is also relatively new in the West (after being abandoned for some very real, very serious safety concerns back in the day), which means there's just less of a R&D infrastructure behind it.
There have been people working on commercializing phage therapy since I was in undergrad (I'm now a tenured professor). The problem is it's hard, and antibiotics are so much better as a treatment that there's kind of a ceiling on the excitement that they can generate, especially when trying to treat at scale.
