O resistance to antibiotics It became, from one moment to another, a problem for the health field. Although it is considered that bacteria could achieve it thanks to genetic mutations, a study published in the scientific journal Physical Review Letters offers a complementary vision.
According to scientists led by Stanford University (United States), the mechanism by which bacteria come together may have to do with this defense. It turns out that Bacteria are usually organized in dense communities. While this forces them to quickly consume their food reserves, at the same time, it allows them to generate a flow of nutrients.
"It's like we open the cockpit lid. There's a flow that drags everything and that's exactly what bacteria do when they form these colonies. This allows, for example, that they reproduce and become active, "Francisca Guzmán, the main author of the article, told the international media.
In this sense, the set of bacteria creates a flow of nutrients and oxygen that arrives where they are and, thus, manages to replenish what it consumes being agglomerated. According to the paper, this organization increases the speed of trawling of nutrients, optimizes its feeding and activity.
With this discovery, the next step is to understand the exact way in which they are assembled to apply new technologies that allow interrupt the flow, prevent them from clumping and – potentially – return some effectiveness to antibiotics. "We found out why it's so hard to get rid of them," said the researcher.
