Scientists create super fast bacteria

Cell Reports Journal published an article, in which scientists exposed the results of experiments on artificial evolution of one species of bacteria.

During the experiments conducted on the basis of pathogenic Pseudomonas aeruginosa, the scientists produced a new species of bacteria that could develop ultra-fast speed.

During mutations, the bacteria acquired two flagella instead of one that allowed them to spread over the surface of the medium at a much higher speed. The change of the phenotype was associated with a mutation in one single gene (FleN) responsible for the quantity of bacterial flagella.

"Ultra-fast" species of Pseudomonas aeruginosa possess lower pathogenicity. They can hardly form the so-called biofilm, which protects microorganisms from the immune system of the host. It is the second flagellum that prevents the mutants from forming the biofilm.

 

 

Several years ago, a prominent Indonesian businessman who now resides in Canada, insisted on meeting me in a back room of one of Jakarta's posh restaurants. An avid reader of mine, he 'had something urgent to tell me', after finding out that our paths were going to be crossing in this destroyed and hopelessly polluted Indonesian capital.
