Molecular analysis of the cholera toxin gene & antibiotic sensitivity profile of Vibrio cholerae O1 & O139 associated with mixed infection.
In the context of the reemergence of V. cholerae O1 in India and the recent evidence that O139 strains could have evolved from O1 E1 Tor strains, restriction fragment length polymorphism (RFLP) of the rRNA and the ctx genes and the antibiotic sensitivity profile of the two strains of V. cholerae, one an O1 and the other an O139, associated with mixed infection, were examined to determine their relatedness. Our results demonstrate that although the strains belonged to different clones of V. cholerae, they showed similar antibiotic sensitivity, profile indicating some exchange of genetic elements.
