Abstract
Jahangirnagar University campus is a hub of several water bodies making it as a heaven for native and migratory birds. This research focused on the microbial quality of three water bodies of this campus where human interference is restricted. Isolation and identification of heterotrophic bacteria, fecal coliform and other pathogenic bacteria were carried out in this study. In the present investigation, Heterotrophic bacterial count varied from 17-100 cfu/ml for Site-1, 19-45 cfu/ml for Site-2 and 17-85 cfu/ml for Site-3. Seasonal trends in bacterial concentrations were also present, where highest concentration was found during winter and lowest one was during monsoon. In case of monthly variation, the highest average was recorded in the month of February for Site-1 and Site-2 and January for Site-3 whereas the lowest mean was recorded in the month of July in all studied sites. No coliform bacteria had been found in the studied water bodies. Bacterial colonies were isolated according to standard protocol and identified on the basis of morphological and biochemical characteristics. This study showed that the isolated bacteria were Bacillus sp. and Staphylococcus aureus that forbidding human activities like swimming or domestic use though water samples were lack of fecal pollution. It may be suitable enough for the indigenous and migratory birds.
