Molecular characterization of O1 strains circulating in Assam: a north eastern state of India.

Background And Objectives: Information on the genetic epidemiology of cholera in Assam, a northeastern state of India is lacking despite cholera being a major public health problem. The study aimed to determine the virulence genes and genes encoding antibiotic resistance in isolates and to determine the prevalent genotypes based on the presence or absence of the virulence genes and genotype.

Materials And Methods: Twenty-five strains were subjected to conventional biotyping and serotyping followed by multiplex PCR to detect and and antibiotic resistance genes.

Prevalence of O1 serogroup in Assam, India: A hospital-based study.

Background & Objectives: Although cholera remains to be an important public health problem, studies on reliable population-based estimates of laboratory confirmed cholera in endemic areas are limited worldwide. The aim of this hospital-based study was to evaluate the prevalence of Vibrio cholerae serogroup in Assam, India, during 2003-2013.

Methods: Stool samples/rectal swabs were collected from acute watery diarrhoea (AWD) cases during 2003-2013 and processed by standard microbiological procedures.
