The genes encoding cholera toxin, one of the principal virulence factors of the diarrhoeal
pathogen Vibrio cholerae, are part of the genome of CTXφ, a filamentous bacteriophage …

Vibrio cholerae O1, the causative agent of the disease cholera, has two biotypes namely the
classical and El Tor. Biotype is a subspecific taxonomic classification of V. cholerae O1 …

The emergence of Vibrio cholerae O139 Bengal during 1992–1993 was associated with
large epidemics of cholera in India and Bangladesh and, initially, with a total displacement …

Antimicrobial susceptibilities of Vibrio cholerae strains isolated from cholera patients
admitted to the Infectious Diseases Hospital, Calcutta, India for 6 years were analysed to …

ABSTRACT CTXφ is a filamentous, lysogenic bacteriophage whose genome encodes
cholera toxin, the primary virulence factor produced by Vibrio cholerae. CTX prophages in …

The novel epidemic strain Vibrio cholerae O139 Bengal originated from a seventh-pandemic
O1 El Tor strain by antigenic shift resulting from homologous recombination-mediated …

Environmental isolates of Vibrio cholerae of eight randomly amplified polymorphic DNA
(RAPD) fingerprint types from Calcutta, India, that were unusual in containing toxin …

Abstract During March and April 2002, a resurgence of Vibrio cholerae O139 occurred in
Dhaka and adjoining areas of Bangladesh with an estimated 30,000 cases of cholera …

ABSTRACT CTXφ is a lysogenic, filamentous bacteriophage. Its genome includes the genes
encoding cholera toxin (ctxAB), one of the principal virulence factors of Vibrio cholerae; …

ABSTRACT IEM101, a Vibrio cholerae O1 El Tor Ogawa strain naturally deficient in CTXΦ,
was previously selected as a live cholera vaccine candidate. To make a better and safer …
