  Streptococcus agalactiae is a contagious mastitis pathogen commonly found in dairies in northern Thailand. During infection, S. agalactiae may form biofilms which is known to be associated with increased antimicrobial resistance of bacteria. We aimed to investigate changes in antimicrobial resistance of biofilm producing S. agalactiae associated with bovine mastitis. We measured biofilm formation, Minimum Inhibitory Concentrations (MIC) and Minimal Bactericidal Concentrations (MBC), and Minimum Biofilm Eradication Concentration (MBEC) of 56 archived isolates from bovine milk in Chiang Mai, Thailand. Quantitative biofilm evaluation found no (0%) strong, 21 (37%) moderate, and 30 (54%) weak biofilm producers, as well as 5 (9%) non-biofilm producers. Qualitative biofilm assay found only 11 isolates (20%) to be biofilm producers; these were further investigated .. Read More»
