Bacteria become resistant to antibiotics when they are "extressed", as discovered by researchers from the University of California in Irvine (United States) and the Paris VII Denis Diderot Faculty of Medicine in Paris (France), in an investigation published in 'BMC Evolutionary Biology '. In particular, E. coli bacteria grown at high temperatures spontaneously become resistant to rifampin.
They live at temperatures of -13 ° C, in water with high concentrations of salt, without light or oxygen. These super organisms are bacteria, and have been discovered by a team of scientists from the Desert Research Institute in Nevada (USA) under the ice of a lake in Antarctica. Their study offers clues about the way of life that the hypothetical inhabitants of other planets with similar environmental conditions would have.
A study published in the New England Journal of Medicine suggests that transplanting donor stool into a person with a recurrent Clostridium difficile infection may be more effective than treating it with antibiotics.
A group of researchers from Michigan State University (USA) has carried out a patient experiment lasting no less than 25 years, during which more than 50,000 generations of Escherichia coli bacteria have been analyzed. As a result, the team has been able to identify mutations in the species that have led to the development of a new function. In other words: the experiment has made it possible to 'see' directly the famous evolution by small changes that Darwin spoke of in the 19th century.
According to a French study published in the journal Nature, the Japanese have large amounts of enzymes in their digestive system, porphyrases, which digest a special type of carbohydrate called porphyrans, present in red algae that are used to prepare food. sushi. These algae, of the genus Porphyra, are what the Japanese call nori.
Why do hundreds of thousands of people get sick and die from antibiotic-resistant bacterial infections each year? According to an article just published in the Journal of Infectious Diseases, a team of researchers from the University of Michigan has shown that bacteria can form clumps resistant to antibiotics in a very short time, even in a liquid in constant flow like blood.
We cannot see them, but they are everywhere. They were the first to inhabit our planet and are able to survive in the most extreme conditions, from the super salty waters of the Dead Sea to the last corner of our stomachs. We are talking about microorganisms, tiny beings that are everywhere and live in the most unexpected places.
Serious infections caused by bacteria increase up to 17% for every ten degrees that the ambient temperature rises, according to a study published in the specialized journal 'Infection Control and Hospital Epidemiology'.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
