Biofilm-forming capacity of G. vaginalis isolates. A) Biofilms were stained with safranin for a visual assessment of biofilm thickness. B) Because the BV-associated isolate AMD exhibited significantly greater biofilm-forming capacity than the non-BV isolate 5-1 we tested an additional non-BV isolate (465) and two additional BV isolates (101 and 551). The percent growth as a biofilm was calculated as OD595 biofilm/(OD595 biofilm + OD595 planktonic) and is represented graphically. The error bars represent standard deviation of 8 independent data points.
