ABSTRACT
During 1992, 1993 and 1994 a total of 65, 123 and 142 faecal samples respectively yielded 9, 54 and 87 strains of V. cholerae. Simultaneous occurrence of EL TOR vibrio and non 01 (i.e. 0139) was noted during 1993 and 1994 with variations in relative and absolute prevalence of each serotype. Seasonal incidence is fairly consistent in this region. Both V. cholerae serotypes 01 and 0139 showed resistance to one or more drugs.

A total of 65 strains of V. cholerae were isolated during June-July 1994 at Yavatmal (Maharashtra). Of the 65 strains isolated, 62 were 01 El Tor Vibrios, while three were non 01 serotype 0139. The novel epidemic strain designated as 0139 reported during the outbreak in 1993, has been supplanted by the usual El Tor Vibrio during the present outbreak while 0139 serotype has remained sporadic.
