Incidence of Vibrio cholerae serogroup O139 infection with low virulence in Hubli, Karnataka (India).
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.
