Cholera has been reported in the state of Odisha, India since more than two decades. The present study was carried out during the year 2000 to 2004 to find out the incidence and molecular analysis of V. cholerae causing diarrhoea among some primitive tribes namely Bondo, Didayi, Juanga and Kondha residing in Odisha, India. Bacteriological analysis of 1066 rectal swabs collected from hospitalized diarrhoea patients in tribal areas revealed 9.8 % were positive for V. cholerae O1 Ogawa and 3.8% for V. cholerae O139 serogroup. The major antibiogram profile of O1 and O139 revealed resistance to ACoFzNNaS and AFzNSNa respectively. The emergence of fluoroquinolone resistant V. cholerae O1 and O139 and 100% nalidixic acid resistant O139 were observed. Cholera toxin production of V. cholerae O1 isolated from the tribal areas exhibited similar to the strains prevail in the endemic coastal districts of Odisha. PCR assay revealed that all the isolates of V. cholerae O1 and O139 were positive for ctxA, tcpA (El Tor), ace and zot genes. Except some minor variation in RAPD profiles, both O1 and O139 strains exhibited similar pattern of PFGE and RAPD among each serogroup compared with the strains of Kolkata and other parts of the state. For the first time, this study revealed that V. cholerae was one of the important aetiopathologic agents responsible for causing diarrhoea in the remote primitive tribal areas in the state, the possible origin and spread of which could be due to the population movement from the endemic areas of the state to the remote tribal areas.
