    A big problem is that pharmaceutical companies would find it more difficult to profit from these because intellectual property around infection-specific phages is not as straight-forward as antibiotics. I'm not sure if this would therefore be the right place for government-funded development instead.

    "we used antibiotics more and more..." - no, agriculture used it more and more on cattle to increase their growth rate. This is where most of the cases of resistant bacteria in Holland come from. Another source are populations with ready access to antibiotics without a doctor's prescription. A lot of countries including the USA and the countries in southern Europe are in this range. They create their own problems. Russia creates even worse problems for itself by having prison populations that are both overcrowded, get *some* medication but not enough. Resistant tuberculosis is a real risk inside Russian prisons. Don't get me started on South America. And the fools that think "oh, it's just prisoners..." - well, they do get out at some point and then infect the general population.
    Having good healthcare was created by people who didn't like dying from poor people's plagues. Apparently, that lesson is forgotten. And pharma has no reason to reminds us of it, as the antibiotics sold to agriculture and humans alike create massive profits. But IMO, they should be reserved for cases where a test confirms a bacterial infection, and nothing else.
