Abstract
Sixty-nine strains of Vibrio cholerae 01 isolated at different times were analysed to investigate if there were any differences among the 01 strains isolated before, during and after the advent of the 0139 serogroup. Of the 69 01 strains examined, 68 belonged to the Ogawa serotype while one belonged to the Inaba serotype. With the exception of one strain all other strains of V. cholerae 01 belonged to the eltor biotype. A single 01 strain isolated before the emergence of the 0139 serogroup could not be classified as either eltor or classical biotype because it was resistant to both classical and eltor specific bacteriophages. Marked variations in the susceptibility to antibiotics of V. cholerae 01 isolated during the different periods were observed. In addition, strains of V. cholerae isolated after the epidemic of serogroup 0139 in Calcutta showed an expanding R-type with resistance to a variety of drugs as compared to the 01 strains isolated before the advent of the 0139 serogroup. From this study, it is clear that there is a substantial mobility in genetic elements of V. cholerae 01 which necessitates a continuous monitoring to keep abreast of the changing traits of the etiologic agent of cholera.
