Virulence gene profiles, biofilm formation, and antimicrobial resistance of non-O1/non-O139 bacteria isolated from West Bengal, India.

is the causative agent of acute dehydrating diarrhoeal disease cholera. Among 71 non-O1/non-O139 isolates, all yielded negative results for , and genes in PCR assay. Few strains were positive for (28.

Prevalence of Panton-Valentine Leukocidin Gene among Community Acquired : A Real-Time PCR Study.

Panton-Valentine leukocidin () is a cytotoxin that causes leukocyte destruction and tissue necrosis. The aim of this study was to determine the prevalence of the , , and genes in isolates obtained from anterior nares and superficial infection sites of skin in a slum population of West Bengal, India. Expression level of gene was also analysed.

Quorum Sensing Autoinducer(s) and Flagellum Independently Mediate EPS Signaling in Vibrio cholerae Through LuxO-Independent Mechanism.

Vibrio cholerae, the Gram-negative bacterium causing lethal diarrheal disease cholera, forms biofilm on solid surfaces to gain adaptive advantage for successful survival in aquatic reservoirs. Expression of exopolysaccharide (EPS), an extracellular matrix material, has been found critical for biofilm-based environmental persistence. In a subset of epidemic-causing V.

Biochemical and Molecular Analysis of Staphylococcus aureus Clinical Isolates from Hospitalized Patients.

Staphylococcus aureus is opportunistic human as well as animal pathogen that causes a variety of diseases. A total of 100 Staphylococcus aureus isolates were obtained from clinical samples derived from hospitalized patients. The presumptive Staphylococcus aureus clinical isolates were identified phenotypically by different biochemical tests.
