Abstract
Pseudomonas aeruginosa is a common organism found in water and its growth can cause problems with color, taste, odour and turbidity of the drinking water. In the present study, a total of 210 water samples were analysed and 40 strains of Pseudomonas aeruginosa were isolated and identified from various drinking water sources from different localities in Amravati city. Antimicrobial susceptibility tests were carried with 24 antibiotics, which showed 47% resistance, and 53% sensitive. The studies reported high incidence (30%) of Pseudomonas aeruginosa in drinking water showing danger to human health due to its biofilm producing ability and indicating emergence of antibiotic resistance due to the indiscriminate use of antibiotics.
