Researchers have observed a phenomenon of cellular ejection in bacterial communities similar to the mechanism by which jellyfish expel their urticating cells / They have taken advantage of this discovery to cause the rupture of these biofilms, which could allow the elimination of antibiotic resistant bacteria Biofilms are communities of bacteria that are found on all kinds of surfaces in our environment. These microscopic groupings are abundant …

I tell you as if we were having coffee: imagine that you are a bacterium and you live so hot in a colony with your colleagues, but suddenly there comes a threat and everything goes down. The colony notices it and, before dying, shoots some of its bacteria abroad. Like the escape pods of spaceships. It is not science fiction: it is what an international team of researchers, with Spanish participation, has just discovered and is published today in…

Biologists from the University of California in San Diego, in collaboration with a research team from Pompeu Fabra University in Barcelona, have discovered that these bacterial communities have a previously unknown ejection capacity. The study is published this Tuesday in Nature Microbiology. Scientists at the University of California in San Diego, led by Professor Gürol Süel, have for the first time documented the ejection phenomenon of biofilm…
