title: Vibrio cholerae O139 Bengal: a descriptive study.
abstract: A prospective study was conducted to determine the clinical and laboratory characteristics and the clinical course of cholera due to Vibrio cholerae O139 Bengal. The study subjects included 22 adult males with stool culture-proven V. cholerae O139. On enrollment, mean +/- SD concentrations (mmol/L) of serum sodium, potassium, chloride, and bicarbonate were 134 +/- 3, 4 +/- 1, 102 +/- 4, and 13 +/- 4 respectively, and stool sodium, potassium, chloride, and bicarbonate concentrations were 120 +/- 24, 18 +/- 6, 93 +/- 16, and 37 +/- 9 respectively. Seventeen patients (7.8%) had faecal leukocytes ranging from 11 to 50 per high-power field. All V. cholerae O139 isolates (100%) were susceptible to tetracycline, erythromycin, and ciprofloxacin, 92% to furazolidine, and only 5% to trimethoprim-sulphamethaxazole. The median (interquartile) volume of liquid stool during the first 24 hours was 9 (5-12) litre. The median (interquartile) volume of liquid stool and the amounts of intravenous and oral rehydration fluids required during the entire study period were 16 (9-24) litre, 9 (6-18) litre, and 14 (9-20) litre respectively. The median (interquartile) duration of diarrhoea was 80 (48-104) hours. The median (interquartile) duration of excretion of V. cholerae O139 in stool was 5 (3-6) days. Clinical and laboratory features, and case management of cholera due to V. cholerae O139 are very similar to conventional cholera due to V. cholerae O1.
