The stool samples are processed as per standard microbiology techniques. For the suspected cholera isolates battery of biochemical test is run for identification of the sero typing of all vibrio cholera. Isolation is done by agglutination with specific antisera. For bio typing and phage typing all the isolates are sent to National Institute of Cholera and Enteric Diseases ( NICED)Kolkata. Results: Out of total 1252 stool samples 39 vibrio cholera isolates on selective media and out of total 30 water culture samples 10 water samples found contaminated. Interpretation & Conclusion: The outbreak of choleral cases were increased in lower socio-economical class and overcrowded area due to poor hygiene and sanitation.
