Aim of this study is bacterial isolation (pathogenic) from drinking water and makes some awareness about waterborne disease. Infectious diseases caused by pathogenic bacteria, viruses and parasites are the most common and widespread health risk associated with drinking water. Water contamination not only affects the developing countries but is also a major problem in developed countries. Thus, contamination of water resources with pathogenic bacteria leading to illness is a major concern throughout the world. The isolated bacteria were confirmed using DNA isolation method and BLAST sequence editing. The isolated bacteria were antagonistic against the standard antibiotics called Cephalexin, Erythromycin, and Amoxicillin. Amoxicillin is Penicillin antibiotic and treats the stomach ulcer which was caused by Helicobacter pylori. Erythromycin and Cephalexin both are bacteriostatic.
