WHO Issues a List of 12 Most Worrying Drug-Resistant Bacteria (medicalxpress.com) 91

Artem Tashkinov quotes a report from Medical Xpress: The World Health Organization has issued a list of the top dozen bacteria most dangerous to humans, warning that doctors are fast running out of treatment options. WHO said the most-needed drugs are for germs that threaten hospitals, nursing homes and among patients who need ventilators or catheters. The agency said the dozen listed resistant bacteria are increasingly untreatable and can cause fatal infections; most typically strike people with weakened immune systems. At the top of WHO's list is Acinetobacter baumannii, a group of bacteria that cause a range of diseases from pneumonia to blood or wound infections. In recent years, health officials have detected a few patients resistant to colistin, the antibiotic of last resort. So far, doctors have been able to treat them with other drugs. But experts worry that the colistin-resistant bacteria will spread their properties to other bacteria already resistant to more commonly used antibiotics, creating germs that can't be killed by any known drugs.

    Since the linked article is still a few clicks away from the actual list, which is then a PDF, here is the actual list:

    Priority 1: CRITICAL
    Acinetobacter baumannii, carbapenem-resistant
    Pseudomonas aeruginosa, carbapenem-resistant
    Enterobacteriaceae, carbapenem-resistant, 3rd generation cephalosporin-resistant

    Priority 2: HIGH
    Enterococcus faecium, vancomycin-resistant
    Staphylococcus aureus, methicillin-resistant, vancomycin intermediate and resistant
    Helicobacter pylori, clarithromycin-resistant
    Campylobacter, fluoroquinolone-resistant
    Salmonella spp., fluoroquinolone-resistant
    Neisseria gonorrhoeae, 3rd generation cephalosporin-resistant, fluoroquinolone-resistant

    Priority 3: MEDIUM

    • This seems like one of those of cases where linking to the source really doesn't benefit the discussion.

      Sometimes abstracting helps understanding rather thanhindering it.

    • I've actually had a couple of those. The Pseudomonas aeruginosa was treated successfully by levofloxcillin (sp?), and I went from insufficient blood pressure to keep my eyes functioning properly to feeling great in 10 days. The Staphylococcus aureus was treated with clindomycin (sp?), which works great, in addition to giving my intestines inspiration to try new and innovative things to do something I had already thought worked satisfactorily. So far, so good.

    A long time slashdot user, I have been offered the opportunity to disable ads in the sidebar on the classic.slashdot.org main page, but wanting to support the site I never disabled it.

    Recently however there have been annoying ads that stay "stickied" on top even when you scroll down and it has been driving me nuts, so finally I decided to use the option. Except it has disappeared! What happened? Does the option only appear under certain circumstances? Did the new overlords remove it and I simply missed my c

    Hi I've never flamed on Slashdot but about 60% of my browser screen is ads. The top 40% and the right 20%. This is intolerable, so even though my "karma" is excellent and my signup number is low seven figures, I'm outtahere.

    Before antibiotics one could get an antiserum against each of many nasty infections. The rise of antibiotics displaced these drugs - even for some things (such as some forms of meningitis) where an antiserum against the particular organism, did a better job.

    This actually made some sense. Antibiotics were broader spectrum, so (even after drug resistant bugs became common) you were likely to find one that worked in time to save the patient. Antisera, on the other hand, were very bug-specific.

    If multiple drug resistance makes antibiotics nearly useless, perhaps it's time to revive antiserum use.

    We now have the technology to rapidly identify the target organism(s) in a disease process, so we can rapidly select the correct magic bullets. And we also have the technology to make specific antisera by the bucketful.

    And without the side-effects of making it by exposing an animal (like a "serum horse") to a pathogen and then (once it's developed an immunity) extracting the (horse-type) antibodies to this - and to everything else its immune system doesn't like - to make the drug. Instead we can make human monoclonal antibodies to just one target.

    We can also engineer an immunization by chopping out the DNA for some conserved region snippet of some pathogen's accessible surface markers, splicing it with neighboring coding that will make the immune system take note and building it into an otherwise (and still) harmless bug - either to make an active ingredient for an immunization cocktail or a variola/polio style live-virus challenge. The bug has a very hard time evolving resistance because a conserved region of some component of its molecular machinery is usually conserved because has to be the way it is for it to work.

    This is already being done to some extent. Seems to me it's time to stop crying about the end of antibiotics and focus on this set of approaches - which should be very lasting.

    • Maybe. But that just begs the question, that a layman would ask: How is antiserum different from vaccination?

      • How is antiserum different from vaccination?

        Four things:
        - Immunization
        - Innoculation
        - Vaccination
        - Antiserum

        An immunization is a challenge to the immune system that looks to it like the target pathogen - often with an adjuvant to do enough minor mischief to convince the immune system that this is a really bad guy that needs a SWAT team response. It might be made out of:
        - pieces of killed pathogen,
        - pieces of killed related pathogen,
        - engineered molecu

  • Despite all the pesky warning and regulations preventing this very situation, we managed to get around all of it and create the most dangerous bacteria that human-kind has ever seen! Everyone, give yourselves a pat on the back because we earned this. I hope you all got biohazard suits so you can safely watch humanity get ravaged by our new little "friends"! ;)

    For some time, Targeted alpha therapy [wikipedia.org] has shown promise for treating difficult cancers, but it may also be used to kill antibiotic-resistant bacteria and pathogens like HIV. Once this capability is developed, the antibiotic arms race will end once and for all. The looming threat is very serious, and such promising research should be a high priority.

    Unfortunately, there are artificial barriers that are retarding progress. The most attractive isotopes for use with TAT are Actinium-225 and Bismuth-213, which no longer exist in nature. Looking at the periodic table, one might be inclined to believe that other substitutes exist, but they simply don’t. The neptunium decay chain [wikipedia.org] is unique in that it does not pass through radon or terminate in lead. Born in supernovae long ago, it was extinct in nature until relatively recently, when it was revived in the heart of nuclear reactors.

    However, conventional reactors don’t produce much, and it is impractical to extract the short-lived isotopes from solid fuel rods sealed in a reactor core. Liquid Fluoride Thorium Reactors however, are the ideal machines for producing these life-saving medical isotopes. Meanwhile, LFTR safely transforms nuclear waste into abundant and inexpensive energy. [thmsr.nl]

    It is worth noting that Flibe Energy [flibe-energy.com] is the only company in the west pursuing this technology; others developing molten salt reactors are trying to take shortcuts which miss out on the greatest benefits of the thorium fuel cycle. LFTR is a comprehensive solution, which can finally close the fuel cycle, eliminating the need for uranium mining and enrichment. It is a more challenging design, but it doesn’t kick the can down the road; it fully addresses all rational concerns with nuclear technology, and offers many new opportunities.

    • Someone can't accept new nuclear, even to save their own life. Chances are very good that you or someone close to you will die from cancer someday, which could have been preventable if ideology didn't blind you. If the fools in government weren't more interested in weapons than energy, this technology would be saving countless lives today, and inexpensive carbon-free energy would be the norm. There is a good article detailing the specifics and history of LFTR [businessinsider.com] for those with a mind open to facts.

      The crusad

    • How do you apply the radioactives to the bacteria without irradiating the patient?

  • No matter how many studies about antibiotics resistance, still in the US they keep on feeding antibiotics to cattle to make them grow slightly faster to make slightly more money. All this at the long term risk of killing most of us. No, that's not hyperbole: before the invention of antibiotics, one skin infection out of 9 was deadly. Yes, a bit of pus in a scrape, deadly one time out of 9, let that soak in (the idea, not the pus).

    I remember a discussion about that here on ./ a decade ago where a moron was defending this feeding, saying "no studies have shown any risk". Then a few years later some studies started tracing out the DNA origin of some resistances and pinpointed them to some US industrial farms, I wanted to find our exchange of posts and rub it in "told you so", but ./ message search sucks ass and I could never find them.
    • Even if you could find them discussions are archived so it wouldn't allow you to reply.

        I know that, but a direct message or, better, a public shaming in a new discussion such as this one. This is too important. Antibiotics shouldn't be given as animal food, and I'm beginning to think that they shouldn't be given to animals at all, period.

      The drugs used by livestock feeders aren't the same ones that worry WHO.

      You're spreading fud; these antibiotic resistant bacteria are caused by inappropriate use of antibiotics to treat humans, mostly (but not entirely) in Third World countries.

      • Any drug formerly effective against any of the bacteria on their list worry the WHO by no longer being effective. Just because they mention only one of the best broad spectrum anti-biotics which they are resistant against doesn't mean those drugs are the only relevant ones. Since someone mentioned colistin was used on animals I did a quick google, Salmonella is on the list and colistin resistance is spreading. By complete coincidence it's used in agriculture for Salmonella infections.

        Even more so though, th

      • but, uneducated opinion here, wouldn't any hint of antibiotic slightly related to the pathogen strengthen any bacteria against it? you know, that whole theory of "whatever doesn't kill you makes you stronger?"... or does that not apply to the microbiology world?

          you know, that whole theory of "whatever doesn't kill you makes you stronger?"... or does that not apply to the microbiology world?

          In the microbiology world, whatever doesn't kill you, but weakens or kills your competitors, makes your progeny (and your resistance) more prevalent. So in the metagenetic sense it makes your germ-line stronger, but it doesn't do much for you specifically (except get rid of your competition).

  • Bloomberg Businessweek a few months ago did an article based on research that found use of heavy duty antibiotics in seafood (mostly shrimp) farming in China. Drugs like colistin are being used. The article talked about how waste from pig farming is somehow used to feed the farmed shrimp. Improting "food" like this into the States is obviously illegal. To add insult to injury, there are shell companies in China, Thailand, etc. set up for the sole purpose of circumventing those legal controls, and the shrimp

  • Easy solution, use temporal discardable pavilions for specific patients and treatments. Should be easy to design. Unless, of course, there IS some psychosis strain that gets a kick from thinking people infected and unable to do anything, subject to the elements and State of Nature again, without choices and overwhelmed, entertained in its own gross infections and diseases development and doctors subscribing the ideology for these clients...

Some people manage by the book, even though they don't know who wrote the book or even what book.
