In -vitro Biofilm Formation of Vaginal Isolates of Streptococcus agalactiae; Effect of pH and Culture Media

Abstract

HIGHLIGHTS Maximum biofilm formation of GBS is at neutral pH (pH 7). At a pH of 4.5, there is a greater reduction in viable cells than at other pH value. At Normal vaginal pH (3.5 - 4.5), biofilm formation by GBS is low. Glucose concentration in the media influences biofilm production. Nutrient rich culture media support biofilm growth.
