Research has uncovered how bacteria which are antibiotic
resistant protect bacteria which are not. For example, in an
infected wound, an antibiotic resistant Gp A Strep will secrete the
bacterial enzyme beta-lactamase. This enzyme will cut apart the
beta-lactam ring on penicillins and cephalosporins. It destroys
those antibiotics. Any other bacterial species in the wound, even
those sensitive to penicillins and cephalosporins, are protected as
well.
