title: Incidence of Vibrio cholerae serogroup O139 infection with low virulence in Hubli, Karnataka (India).
abstract: 384 stool samples from patients with acute gastroenteritis were processed by standard culture techniques and antibiogram of V. cholerae was performed. Stool samples from 93 (24.22%) patients yielded V. cholerae, 58 (62.37%) of which were V. cholerae, El Tor O1 Ogawa, 31 (33.33%) V. cholerae O139 and 4 (4.30%) V. cholerae non O1 non O139. Of the culture proven cholera cases watery diarrhoea was observed in 79 (84.95%), vomiting in 57(61.29%), muscle cramps in 21 (22.58%) and sweating in 18 (19.35%). Majority of these patients presented with moderate dehydration 57 (61.29%). Mild dehydration was found in 19 (20.43%) and severe dehydration in 17 (18.28%). While majority of patients with O139 infection had mild to moderate dehydration 25 (80.65%), severe dehydration was more common with O1 infection 11 (64.71%). This study reflects the importance of monitoring the V. cholerae by serogrouping, antibiogram typing, which keep on varying constantly.
