Epidemic of Vibrio cholerae serogroup O139 in Berhampur, Orissa.
During the months of May-June 2000, 194 patients with watery diarrhoea were admitted to the Infectious Diseases Ward of the M.K.C.G. Medical College, Berhampur. Ninety four rectal swabs were collected and processed according to the standard procedures. Vibrio cholerae strains were isolated from 20 samples. Of these 20 isolates, two were found to be V. cholerae O1 EITor Ogawa strain and 18 were confirmed to be V. cholerae serotype O139. All V. cholerae O139 isolates were of a single phage type (phage type 1) and the two O1 strains were of phage type 3 and phage type 27 respectively. All 20 V. cholerae isolates were positive for CAMP test, and showed uniform resistance to furazolidone and sensitivity to co-trimoxazole, amoxycillin, norfloxacin, tetracycline and gentamycin. V. cholerae O139 serotype has not been reported earlier in south Orissa. This is probably the first report of its isolation from this area.
