It is well known that bacteria can swim against the current, which often causes serious problems—for example, when they spread in water pipes or in medical catheters. To prevent or at least slow down the spread of bacteria contaminating biological or medical ducts, scientists need to know how they swim against the flow. An international research team, including the group of Anke Lindner and Eric Clement at PMMH lab from ESPCI Paris (PSL University), was recently able to answer this question with the help of experiments and mathematical calculations. The results describing all essential aspects of this amazing bacterial behavior have now been published in Nature Communications. These insights could contribute to the design of medical devices that hinder the upstream progress of bacteria.
