Fig. 2From: Antibiotic resistance, biofilm formation, and virulence genes of Streptococcus agalactiae serotypes of Indian origina Percentages of strong and moderate biofilm producers among the 30 GBS strains. b Biofilm formation of GBS strains based on crystal violet assays (CVA). Optical density at 595 nm indicates biofilm formation capacity. Of the 30 GBS strains, the G24 (NT) strain had the strongest biofilm formation capacity, whereas the G7 strain (NT) had the weakest (but still moderate) biofilm formation capacity. PC: positive control (Pseudomonas aeruginosa) [27]. NC: negative control (THB + 1% glucose medium) [28]Back to article page
