Enhanced Broth Media for Selective Growth of Vibrio vulnificus

Rapid detection of Vibrio vulnificus can be enhanced by optimizing the components of enrichment broth. PNC (5% peptone, 1% NaCl, and 0.08% cellobiose [pH 8.0]) enhanced the growth of V. vulnificus compared to alkaline peptone broth. PNCC (PNC with 1.0 to 4.1 U of colistin methanesulfonate per ml) increased the growth of low levels of V. vulnificus while suppressing non-target bacteria.
