Bacteria are our main opponents – because they are constantly developing and developing a high degree of resistance to absolutely all types of antibiotics, with which we are trying to defeat them. It becomes clear that in the future, where viral bacteria can easily beat us on drugs, the future is rather bleak, and therefore a team of bacteriologists from several universities in the USA and Canada presented their new study on the molecular process that underlies DNA of bacteria, even after a rather dangerous antibiotic.
As an example, the specialists took several bacterial colonies of the E. Coli strain and conducted experiments on the effects on their DNA using different types of chemical compounds and medicinal drugs. One of these compounds called ciprofloxacin was the most interesting and powerful in terms of resistance to dangerous bacteria – in fact, it managed to destroy most of the DNA structure of E. Coli bacteria.
However, scientists also noticed that from 10% to 25% of the total number of bacteria of this virus family began to go through a very unusual molecular process – as their DNA recovered, the bacteria released so-called reactive oxygen cells, which are extremely dangerous for themselves, thereby making the initially dangerous chemical environment even more dangerous for itself. This means that bacteria specifically form such a dangerous environment in order to more quickly develop adaptation and resistance to even more dangerous environments, which can come from even a more antibiotic, which is more powerful in its properties, which cannot but surprise.
Even in spite of the fact that only up to a quarter of bacteria produce such increased resistivity, the indicator still remains very high – it is worth noting that scientists see this as an excellent opportunity to study new methods and ways to improve subsequent antibiotics. But more importantly, it can help in the initial disarming of bacteria in the future.
