Observing the Proliferation of Salmonella spp. in Karnaphuli River: Catastrophic for the Riverbank Dwellers.

Abstract

Abstract The quality of Karnaphuli river water has an important role in human infection and disease sheltered near Karnaphuli river along with the people of Chittagong. The present study was conducted to systematically examine the prevalence of indicator and pathogenic microorganism Salmonella spp. in water and sediment samples along with their relation with some physiochemical parameters like pH, salinity, DO, temperature, etc. during the post-monsoon time in September. A total of 6 water samples from 6 different stations were taken and samples were examined by the pour plate culture method along with chemical and biological tests for detection of Salmonella spp. This study showed that all water and sediment samples were positive for Salmonella species. There were significant differences between Station no. 2, referred to as Firingee Bazar, and the 6th station, known as Soltgola. The present research shows that pollution indicator like DO and the amount of cell of bacteria prevails in the unhygienic and polluted situation of the river which is a clear picture of uncontrolled hazardous activity.
