Seasonal occurrences and distribution of vibrio at Busan markets in Korea

Abstract

Cholera is etiological agents of cholera. Samples contaminated with <i>Vibrio cholera, V. parahaemolyticus </i>and <i>V. vulnificus </i>were identified using PCR with primers. We showed that fish and mollusks served as intermediate vectors of <i>V. cholera, V. parahaemolyticus </i>and <i>V. vulnificus </i>at Busan city in Korea. Three species was found in the examined fish and mollusk at all markets in Busan and was found in all seasons. In most cases, the bacteria were isolated from the epithelial intestines of fish. Only three species of molluscs were contaminated with <i>V. parahaemolyticus</i>. <i>V. vulnificus </i>was found in <i>Sebastes pachycephalus </i>(Jacopever, Schlegel’s blac rockfish)

and <i>Anguilla</i><i> japonica </i>(Japanese eel).
