TRYPTONE YEAST EXTRACT CYSTINE W/ SUCROSE & W/O BACITRACIN AGAR BASE

Description

TYCSB Agar is devised by Gold et al. as a selective medium for Streptococcus mutans with bacitracin and sucrose. Streptococcus mutans is facultatively anaerobic, Gram-positive coccus-shaped bacterium commonly found in the human oral cavity. It is the primary causative agent of dental cavities. Conditions in the oral cavity are diverse and complex, frequently changing from one extreme to another. Thus, to survive in the oral cavity, S.mutans must tolerate rapidly harsh environmental fluctuations and exposure to various antimicrobial agents to survive.
