Studying Vibrio Genus in Surface Waters of Khuzestan Province after the Flood in Spring of ۲۰۱۹

Background and Aim : Vibrio genus are halophilic bacteria, negative gram and curved bacilli, which are usually found in seawater and fresh water. At least ۴۰ species of this genus have been identified, ۱۲ of which are pathogenic to humans and the type species is Vibrio cholerae. The aim of this study is to identify pathogenic species of Vibrio in Khuzestan province surface waters after the flood in the spring of ۲۰۱۹.Methods : Ten samples of surface water and rive water from ۵ cities of Khuzestan province (Ahvaz, Ramhormoz, Masjed soleyman, Izeh, and Baghmalek) were collected and Thiosulfate-citrate-bile salts-sucrose agar and Alkaline Peptone Water culture methods were used for the primary isolation of Vibrio. The exact species identification was done by performing biochemical tests. The V.cholerae strains isolated were serotype by using specific antisera test to identify V.cholerae O۱.Results : Of ten samples, ۹ were of non-O۱ Vibrio cholerae and ۱ was identified to be Vibrio cholerae O۱ whose strain was Ogawa.Conclusion : This study showed that Vibrio pathogenic species was observed in the surface waters of Khuzestan province after the flood.
