ABSTRACT
A total of 130 Vibrio cholerae strains isolated during November 1989 to December 1992 from the rural population of Loni areas--Ahmednagar district of Maharashtra were characterised. Of these isolates, 124 were El tor vibrios serotype Ogawa, and 6 were El tor vibrios serotype Inaba. One hundred twenty two strains belonging to T4 phage, while 8 strains of El tor vibrio serotype Ogawa were untypable. All the strains isolated, showing haemolytic and non-haemolytic colony variants of El tor V. cholerae, and had resistance of one or more antibiotics.

Of the 77 Vibrio cholerae isolated during July to September, 1988, 76 were El Tor vibrios serotype Ogawa, 68 belonging to T2 phage (eight strains untypable). Peak incidence was noted in the month of August, 1988. Haemolytic and non-haemolytic colony variants of El Tor V. cholerae were encountered. All strains showed resistance to one or more antibiotics. No fatality was reported during the epidemic. The epidemiological data collected over the past three years (1986-88) show that cholera is prevalent in the local environment.
