In particular, a class of bacteria called 'Gram-negative bacteria,' which include the well-known species E. coli, are causing major problems in our hospitals. The problem is that most antibiotics that we know today work according to only a few mechanisms of action and so when a bacterium becomes tolerant to one drug,Ãâà...
