Rapid Method for Species-Specific Identification of Vibrio cholerae Using Primers Targeted to the Gene of Outer Membrane Protein OmpW

Nandi, Bisweswar, Nandy, Ranjan K., Mukhopadhyay, Sarmishtha, Nair, G. Balakrish, Shimada, Toshio, Ghose, Asoke C.

The distribution of genes for an outer membrane protein (OmpW) and a regulatory protein (ToxR) in Vibrio cholerae and other organisms was studied using respective primers and probes. PCR...

Emergence of Vibrio cholerae O1 Biotype El Tor Serotype Inaba from the Prevailing O1 Ogawa Serotype Strains in India

Garg, Pallavi, Nandy, Ranjan K., Chaudhury, Papiya, Chowdhury, Nandini Roy, De, Keya, Ramamurthy, T., ...

The toxigenic Inaba serotype of Vibrio cholerae O1 biotype El Tor reappeared in India in 1998 and 1999, almost 10 years after its last dominance in Calcutta in 1989. Extensive molecular...

Molecular Characterization of a New Variant of Toxin-Coregulated Pilus Protein (TcpA) in a Toxigenic Non-O1/Non-O139 Strain of Vibrio cholerae

Nandi, Bisweswar, Nandy, Ranjan K., Vicente, Ana C. P., Ghose, Asoke C.

A toxigenic non-O1/non-O139 strain of Vibrio cholerae (10259) was found to contain a new variant of the toxin-coregulated pilus (TCP) protein gene (tcpA) as determined by PCR and Southern...

Vibrio Pathogenicity Island and Cholera Toxin Genetic Element-Associated Virulence Genes and Their Expression in Non-O1 Non-O139 Strains of Vibrio cholerae

Sarkar, Amit, Nandy, Ranjan K., Nair, G. Balakrish, Ghose, Asoke C.

A non-O1 non-O139 Vibrio cholerae strain, 10259, belonging to the serogroup O53 was shown to harbor genes related to the vibrio pathogenicity island (VPI) and a cholera toxin (CT) genetic element...

Environmental Isolates of Aeromonas spp. Harboring the cagA-Like Gene of Helicobacter pylori

Datta, Simanti, Khan, Asis, Nandy, Ranjan K., Rehman, Motiur, Sinha, Sutapa, Chattopadhyay, Santanu, ...

We investigated the presence of cagA-like gene of Helicobacter pylori in environmental isolates of Aeromonas spp. from different water samples of Calcutta, India, by colony hybridization using a...

Virulence Characteristics and Molecular Epidemiology of Enteroaggregative Escherichia coli Isolates from Hospitalized Diarrheal Patients in Kolkata, India

Kahali, Soumen, Sarkar, Bhaswati, Rajendran, K., Khanam, Jasmina, Yamasaki, Shinji, Nandy, Ranjan K., ...

Enteroaggregative Escherichia coli (EAEC) is an important diarrheal enteropathogen defined by aggregative adherence to cultured epithelial cells. We have detected EAEC from 121 (6.6%) of 1,826...
