Biologists may have discovered how bacteria reproduce in the small intestine

Even today, many mechanisms taking place in the human body remain a mystery to science. Fortunately, thanks to new approaches to technology, new discoveries are made. This is how recently a brilliant team of scientists put their finger on one of the mechanisms of transfer genetic information within populations bacterial.

Indeed, these researchers discovered the existence of the sex bacteria within the intestine hail. At first, these biologists thought they were in the presence of a mechanism for transferring antibiotic-resistant genes. However, experiments much more in-depth bring results more surprising than nature.

These discoveries were made by a team of researchers from the University of illinois at UrbanaChampagne and the University of California at river side. In addition, Patrick Degnan microbiologist was part of the group.

Explanation of the famous coupling mechanism

In order to better understand the different defense and survival mechanisms of microorganisms present in the small intestine, experiments were carried out. At the end of these experiments, the scientists discovered that the bacteria would have the capacity to mate.

In fact, by forming a union temporary » with another bacterium of the intestine, a microbe can transfer its genes to another bacterium, even being from another species. For this, it is enough that the latter takes out a tube, named ” pilus and fixes it to another cell, then expels a packet of DNA transferable, called ” element genetic mobile. »

Lately, it’s become clear that bacterial sex doesn’t just happen when microbes are attacked. It happens all the time and is probably part of what keeps the microbiome fit and healthy. In addition, new research has identified the Genoa bacteria share when they do this.

An excellent mechanism for transmitting information

In order to better highlight the terms of transfer information between bacterial populations, the scientists went further in their experiments. For this, mouse have been studied and researchers have identified carriers of vitamins B12 shared by the bacterial sex.

After this astonishing discovery, these biologists were able to confirm that bacterial intercourse also serves to transmit a multitude of forms of genetic information.

“We are excited about this study because it shows that this process is not just related to antibiotic resistance. »

Mr Degnan

To go further, the scientist continues in these terms:

“Horizontal gene exchange between microbes is probably used for anything that increases their ability to survive, including sharing [des gènes pour le transport de] vitamin B12. »
