[Comparison of the activity against Streptococcus mutans of a chlorhexidine-based antiseptic as a suspension or as a biofilm].

When bacteria colonize a surface they form a biofilm whose susceptibility to anti-microbials is different from that of the same bacterial species forming a homogeneous suspension in a liquid. This study investigated colonization of an inert solid phase (Tygon) with Streptococcus mutans ATCC 25,175--one of the strains involved in the initiation of cariogenic… CONTINUE READING
