Abstract
The aim of this study was isolation and identification of Enterohemorrhagic Escherichia coli 0157 from wastewater in Abattoir environment in Ijebu-North Local Government, Ogun State, Nigeria. Isolation of bacteria was done by pour plate method using Eosin Methylene Blue Agar. First line confirmation of E. coli 0157 was done by streak on Tellurite Sorbitol MacConkey Agar. Antimicrobial susceptibility testing was by disk diffusion method. A total of forty bacteria isolates were recovered and none were found to be 0157 strain. The total Escherichia coli count for each samples ranged from 3.2 × 106 Cfu/ml to 4.0×107Cfu/ml. Sample Ig5--7 had the highest count with 4.0×107Cfu/ml while the least count was obtained from Ig4-6 sample with 3.2 × 106 Cfu/ml. All the sample location has high microbial load. Generally, susceptibility to Cefoxitin and Gentamycin was the highest. Thirty-six isolates were susceptible to Cefoxitin and Gentamycin which is equivalent to 90%. Ten isolates were susceptible to Meropenem which is equivalent to 25%. Eight isolates which is equivalent to 20% were susceptible to Ceftriaxone. Most of the isolates were not susceptible to common antibiotic which call for concern for every individual in come in contact with this wastewater. So it may be recommended that the waste water should be treated before discharge because its discharge to water body is a serious public health issue because of the presence of indicator organisms as well as possible pathogens.
