Against superbugs: Russian science discovered the source of new antibiotics

The antibiotics we know today don’t work anymore. That’s why superbugs – bacteria resistant to modern antibiotics kill some 700 thousand people each year. An equivalent to the population of Detroit, Montenegro or one of Siberia’s largest cities – Tyumen Nightmare superbugs No new antibiotics in the pipeline End of the road for antibiotics unless we act urgently There is hope for mankind though: these little Amphipoda crustaceans from lake Baikal may be the answer. In 2013, biochemists from Irkutsk in Siberia decided to find out how these Baikal Amphipoda protect themselves from infection given that their main source of food is dead organisms found on the bottom of the lake. Turns out… there are actinobacteria living on the crustaceans that produce exactly what researchers worldwide have been looking for – new antibiotics. Antibiotics, which are produced in the Baikal crustaceans, Baikal organisms and bacteria, are extremely effective. It was Alexander Flemming, the man who discovered the first antibiotic – penicillin, who warned how adaptable the bacteria was. He urged people to use antibiotics only on prescription and to stick to treatment. Otherwise the pathogenic bacteria becomes immune instead of dying. So when penicillin’s mass production started in 1943 it took just four years for the first bacteria immune to the antibiotic to be discovered in 1947. The “Golden Age” of antibiotics came to an end in the 80s when scientists stopped discovering new active compounds. So to save hundreds of thousands of people dying from superbugs, the world needs a wealthy source of previously unknown chemical compounds. One that could last for years to come. But let’s go back to the Amphipoda crustaceans. Why are they unique? First of all: the actinobacteria that live in them are very diverse. Your average fresh-water basin may be home to 1 sometimes 2 amphipoda species. While more than 350 amphipoda have been spotted and documented in lake Baikal alone. Through millions of years of evolution the Baikal Amphipoda managed to occupy all kinds of eco niches, and scientists believe there are actually more than a thousand of different species living in the World’s deepest lake. Also… Baikal Amphipoda are great at adapting to extreme conditions. Baikal’s average temperature during the year rarely goes above 4 degrees centigrade – that’s pretty cold. Food sources in Baikal are scarse. Deep-water crustaceans dine on whatever falls onto the bottom of the lake – dead organisms most often a fine menu of detritus. And the antibiotics that the amphipoda produce help them to safely consume even infected organic matter. Back in the 70s this ability to adapt by the Baikal Amphipoda led to some unexpected consequences. A particularly ancient species of the Baikal Amphipoda, the Gmelinoides fasciatus, were introduced into the waters of Volga – to feed the local fish. Milder temperatures and conditions allowed the amphipoda to spread all the way into Lake Ladoga and Lake Onega and then out into the Rivers of Western Russia within just a few decades. This diversity and ability to adapt to extreme conditions of the Baikal Amphipoda and actinobacteria resulted in the potential discovery of tens of thousands new antibiotics. It’s the jackpot scientists were waiting for. We already have working materials. We understand what we’re working with. We know where to look, and where not to look. We know which type of crustaceans to study and which – not to. We have conducted a huge preliminary screening concerning thousands of actinobacteria. In just five years, scientists from the Baikal Research Centre and the Irkutsk State University discovered 15 new antibiotics, currently under the name – Baikalomitsin. It’s a year’s long journey for a crustacean to turn into an antibiotic. Scientists have two main spots where they source the crustaceans. The small town of Bolshie Koti on Baikal’s shore. This is where deep-water crustaceans are caught. … and the town of Listvianka near the non-freezing riverhead of Angara. Nets are used here to catch coastal crustaceans. Crustacean mush then finds its way onto Petri Dishes to culture antibiotics producers. The dishes are placed into warm (some 28-30 degrees centigrade) thermostats to cultivate bacteria. Then strains are selected from what has grown, followed by a screening that defines which bacteria the substance is most active against. Around 80% of the actinobacteria we pick out is active against at least one strain of microorganisms. The most active substance is cultivated in larger quantities and gets turned into pure substance. And this is the result of our work – this ampoule contains 150 natural compounds but also 2 new antibiotics. I don’t see any technical issues and I think that it’s possible to create a new antibiotic every month. If all goes to plan – this could be achieved in 8-10 years. And here’s a fun fact before we go: remember how we said the deep-water crustaceans eat anything that falls to the bottom of lake? Well local police stop searching for the drowned in 10 days… because that’s exactly how long it takes for the crustaceans to devour an entire human body.

  1. Lake Baikal is a real Russian treasure! The world's deepest lake – that sounds incredible!
    I'm sure it still keeps lots of secrets. And I hope that soon we all will be cured only by Baikalomizin 👍😌

  2. Interesting report, and a light of hope for the humanity! One little problem though: whoever writes summaries for RB should re-take an English spelling course. I've noticed two mistakes in a four-sentence post (see above): it's "resistant" and not "resistent" (a very common mistake); and "exactly" should be spelled correctly, too. Thank You.

  3. This is such an amazing discovery! 😀
    I do have a question, though. Does Russia have the issue of anti-vaxxers being a trend?

  4. Under any other circumstances, this episode of Popular Science series would have been taken for its face value but taking all in all into account it is still propaganda although this time it is thoughtfully crafted with full attention to details in the best Western style.

    Any feat of science belongs to the entire humanity regardless of everything else and, unlike ballet fouettés, remains with mankind forever even after becoming obsolete.

    PS A leopard cannot change its spots.😂🤣😂🤣

  5. Good for Russia! The number one reason why I am a big fan of Russia is because Russia, like China, is always in the vanguard in doing positive things that benefit mankind as a whole. On the other hand, my country, America, seems to be hellbent on spreading wars, chaos, and human suffering wherever we go. It's a very sad situation, indeed.

  6. :An antibiotic super bug fungus was found in the Mount Sinai hospital in the upper east side of New York City today.

  7. Теперь я знаю как избавиться от трупа😄👍шутки шутками, но если это действительно не сказочный трёп, а будет развиваться и давать серьёзные результаты, то это круто. Вот только до простых россиян эти антибиотики дойдут лет через 100. Ибо Россия…

  8. Out of curiosity, does the Russian government conduct many studies into the psychology of those who lost their home to the Soviet Union’s fall? In one of your previous videos you were discussing how a majority of Russians miss the Soviet Union, and it was mentioned that many would choose to revive the nation. I know that many of these people lost their home to time, as in the nation disappeared, and not to place, as the states of the USSR largely resemble their previous borders and still exist in the sense one can physically return to their roots and still find “home”. So I’d just like to know how does losing your home to time affect a person. When one’s home is lost physically, the grieving process is easy as there is recognition of the loss of something tangible; but when one loses their home to time, how does that affect them? One could return to the physical location, but with the dramatic changes that have taken place, is home still home today?

  9. Как же это ужасно что из-за рук чиновников такое озеро уже сильно загрязняется

  10. Your last fact reminds me of alligators here in Florida. They are one of the few animals with a digestive system so acidic that it dissolves human bone. Want something totally gone? Feed it to a gator.
