Is there a link between Streptococcus intermedius competence and antibiotic stress? Investigation of biofilm and susceptibility responses.

Abstract

Bacteria have the ability of living both in a planktonic form, as free floating cells, and in biofilm communities. To survive against the many different factors which may affect their ability to grow in their habitat, bacteria may switch from planktonic to biofilm form and visa versa. A biofilm consists of bacteria with a three dimensional organization, enveloped in extra cellular polymeric substances, as well as networks of intervening water channels.
