In laps,bacteria may swim freely,but out in the world,including our bodies,bacteria often exist packed together in dense 1 communities called biofilms. and these configurations 2 can help them cause illness.finding clues about how such bacteria group together could thereforely better therapies to prevent infections and fight disease.with that idea in mind,researchers looked into a biofilm assembling bacteria in a XXX for causing infections and urinary track and along the patients with XXX.they scour 3 the genome that of difference in strength in bacteria for genes 4 that affect movement,and particular genetic 5 mutations ,make the bacteria super strong swimmers,that talent enables them to easily move away from each other,a phenomenon called “hyperswarming”.the mutations that also make it harder for the bacteria to stick together ,until the biofilms associate with illness,the study is in the Journal S.a better understanding of how to keep bacteria apart could lead to technics for stopping biofilm formation,which could translate into treatment for those diseases that depend on bacteria really getting stuck on each other.
