Vibrio cholerae O1 Ogawa strains carrying the ctxB7 allele caused large cholera outbreak during 2014 in the tribal areas of Odisha, India. Jpn J Infect Dis. 2017 Jul 01;: Authors: Bhusan Pal B, Kumar Khuntia H, Ranjan Nayak S, Mohanty A, Biswal B Abstract The large outbreak of cholera reported during July to Sept, 2014 in Narla block of Kalahandi district was investigated to find out the causative organism. The rectal swabs collected from diarrhoea patients and environmental water samples were sub-cultured following standard techniques. The causative organism was V.cholerae O1 Ogawa biotype El Tor while DMAMA-PCR assay confirmed that all strains were ctxB7 of Haitian variants V.cholerae O1. The water samples were negative for V. cholerae .The V.cholerae O1 strains were sensitive to tetracycline, ciprofloxacin, norfloxacin, ofloxacin, doxycycline, azithromycin,; but were resistant to erythromycin, gentamicin, chloramphenicol, furazolidone, neomycine, cotrimoxazole, nalidixic acid and ampicilin. The early reporting of the pathogen enabled the government authorities to implement adequate control measures in time to check the spread of the disease. This is the second large cholera outbreak due to Haitian variants of V.cholerae O1 after the Haiti cholera outbreak during 2010 reported from Odisha, India and also from the globe. Active surveillance is required to track the spread of this strain in this region. PMID: 28674316 [PubMed...
