Bacteriological Assessment for Different Water Resources, Ka'am Region, Libya

Abstract

Objectives: The principal sources of drinking water in the state of Libya are desalinated and underground well water. This study was carried out to determine the bacteriological quality of drinking and cultivation water obtained from the stream surface and wells water of the Ka'am Valley in Al-Khoms and the susceptibility of isolated bacteria to antimicrobial agents.
 Methods: Water samples taken from 80 different sources were examined for coliform, Escherichia coli, and also, Isolated bacteria were tested for their resistance to antibiotics by the BD Phoenix Automated Microbiology.
 Results: Of the water samples examined, 3 (3.75%) were positive for Escherichia coli, 46 (53.49%) for Coliform spp., and 37 (43.02%) for other gram-negative bacteria. 100% of the bacteria examined were resistant to at least one used antibiotic.
