To control germs, scientists deploy tiny agents provocateurs

...U.S. National Institutes of Health study last year reported that almost 80 percent of bacterial infections are in the biofilm forma. Biofilms can often constitute several species of bacteria and can be both harmful and beneficial. In one role, biofilms can coat plant roots and symbiotically aid ecological pr...
