ISOLATION, IDENTIFIATION AND ANTIMICROBIAL SUSCEPTIBILITY OF E.COLI IN RAW COW MILK

Description: This study focused on the comprehensive analysis of Escherichia coli (E. coli) in five samples of raw milk, aiming to identify, isolate, and evaluate the antimicrobial susceptibility patterns of the isolated strains. Standard microbiological techniques were employed for the identification and isolation of E. coli, while antimicrobial susceptibility testing was conducted using the disc diffusion method. The comparative analysis of the five raw milk samples revealed variations in the prevalence and susceptibility patterns of E. coli strains. A total of 5 samples consisting of fresh raw cow milk. Subsequently, 3 isolates of E. coli were isolated from 5 samples of the total analyzed samples. From 3 isolated E. coli, they showed (83%) resistance to Tetracycline. On the other hand, all isolates were 100% sensitive to nalidixic acid, 11.11% were sensitive to Penicillin G, and 100% sensitive to gentamicin. This study contributes to the understanding of E. coli contamination in raw milk, emphasizing the need for targeted surveillance and control measures to ensure the safety of dairy products. The comparative analysis provides valuable insights into the diversity of E. coli strains in different raw milk samples, informing future strategies for mitigating potential public health risks.
