Enhanced broth media for selective growth of Vibrio vulnificus

Vibrio vulnificus is an invasive organism found in oyster meat. It causes life-threatening diseases in humans even at low levels of concentration. This necessitates the use of enrichment broths to facilitate cultivation for diagnostic purposes. A study was launched to determine the components of the enrichment broth that could enhance the selective growth of the organism. V. vulnificus was found to grow better in a broth mixture of peptone, sodium chloride and cellubiose. Colistin methanesulfonate further increased growth while suppressing non-target bacteria.
