Abstract title-Antibiotic Sensitivity of Escherichia Coli And Salmonella Species Isolated From Overhead Water Tanks In Student’s Hostels, Malete, Nigeria

Mayowa Johnson Abioye

Ground water pumped into overhead tanks is the major source of drinking water for most Students in their Hostels in Malete. This study examined the occurrence and antibiotic sensitivity profile of Escherichia coli and Salmonella sp in ten Students Hostels within Malete using standard microbiological and physiochemical methods. In-vitro antibiotic sensitivity patterns were determined using the disc diffusion technique. The result showed that pH (at 25-270C) ranged from 7.0-8.0. The mean total viable count ranged from 1.1 to 2.3 x 104 CFU/ml while mean total coliform count ranged from 0.3 to 1.3 x 104 CFU/ml. The frequency of occurrence of isolates was two E. coli, and a Salmonella sp from three out of the ten Hostels examined.
