Isolation of coliform bacteria from surface and drinking water in Gada-Shagari, Zango-Daji community, Lokoja, Nigeria and their characterization using antibiotic resistance profile
Abstract
Adequate supply of safe and sanitised fresh water is an inevitable and distinct factor for human and economic development. However, in many parts of the developing countries like Nigeria, water pollution caused by fecal contamination is a serious problem due to the potential for contracting diseases from pathogens. The aim of this study was to isolate and identify coliform bacteria from various raw water sources as well as the drinking water distributions system in Gada-Shagari, Zango Area, Lokoja, Nigeria and to characterize their antibiotic resistance profiles. For the sole purpose of reference convenience, the entire community was divided into; Gada-North (GN), Gada-South (GS), Gada-East (GE), Gada-West and Gada-Central (GC). The sampled water were analysed for the presence of coliform indicator bacteria using standard microbiological assay for the detection and enumeration of coliforms and antibiotic susceptibility tests by agar well diffusion technique. Faecal and total coliforms were detected both during dry and rainy season in most of the water samples. Multi-drug resistance was found among E. coli, Citrobacter sp., Pseudomonas p. and Salmonella sp. All isolates were susceptible to kanamycin. The result from this work indicates that the main water supply for the community under study is grossly contaminated with bacteria pathogens which could be life threatening. In addition, some of the associated bacteria were resistant to some classes of antibiotics. Hence, adequate awareness of good hygiene practice, sanitary education as well as provision of basic water supply is urgently needed in the studied community because both animal and humans are at risk of various waterborne diseases.
