Aims: To study the incidence of Vibrio parahaemolyticus in seafoods, water and sediment by molecular techniques vs conventional microbiological methods. Methods and Results: Of 86 samples analysed, 28 recorded positive for V. parahaemolyticus by conventional microbiological method, while 53 were positive by the toxR-targeted PCR, performed directly on enrichment broth lysates. While one sample of molluscan shellfish was positive for tdh gene, trh gene was detected in three enrichment broths of molluscan shellfish. Conclusions: Direct application of PCR to enrichment broths will be useful for the rapid and sensitive detection of potentially pathogenic strains of V. parahemolyticus in seafoods. Significance and Impact of the Study: Vibrio parahaemolyticus is an important human pathogen responsible for food-borne gastroenteritis world-wide. As, both pathogenic and non-pathogenic strains of V. parahaemolyticus exist in the seafood, application of PCR specific for the virulence genes (tdh & trh) will help in detection of pathogenic strains of V. parahaemolyticus and consequently reduce the risk of food-borne illness.

Escherichia coli is the greatest cause of primary urinary tract infections. The present study aimed Urinary tract infection in female with special reference Escherichia coli and its antibiotic susceptibility pattern. A total of 100 urine samples were collected from different hospitals of Allahabad. The samples were cultured on Cystein lysine electrolytes deficiency media, MacConkey’s agar, Nutrient agar and Hicrome UTI agar media. Based on the results it was found that different media had different properties and Hicrome UTI agar was the best and convenient media for the isolation of Escherichia coli and other uropathogens. Further it was also observed that Escherichia coli was the most common organism for UTI in female.
