Background: Diarrhoea is one of the main causes of morbidity and mortality of in developing countries. Bacterial diarrhoea is commonly caused by salmonella, shigella, campylobacter species, and diarrheogenic Escherichia coli. Of the pathogens causing diarrhoea, shigella continues to play a major role in etiology of inflammatory diarrhoea and dysentery. Thus, it presents a serious challenge to public health authorities worldwide. The objective was to know the prevalence of shigella, salmonella and vibrio in patients suffering from diarrhoea Methods: This study was conducted in microbiology department of district hospital over period of July 2015 to July 2016. We had collected total 424 stool samples. From this first we had done routine microscopy of all samples and then inoculated it on various culture media and enteric pathogen were identify by biochemical reaction and by agglutination with anti-sera. Results: From 424 stool samples, we isolated, shigella species 10 (2.3%), Vibrio cholerae 6 (1.4%) and Salmonella species 3 (0.7%). Conclusions: Results of study reveal that shigella species is predominant bacterial entero-pathogen causing diarrhoea and shigella is among highly resistant isolates while salmonella isolates had least resistance to majority of antibiotics. Vibrio cholerae is a major contributor to the diarrhoea causing severe dehydration.
