Prevalence and Antibacterial Susceptibility Pattern of Escherichia Coli in Fermented Cow Milk Collected from Selected Markets in Maiduguri, Borno State.

Abstract

Escherichia coli is an enteric food borne pathogen associated with life-threatening disease conditions. The enterobacteria are frequently found in the cattle gastrointestinal tract with a high potential of contaminated animal products such as milk, meat, and cheese. A cross-sectional study was conducted to investigate the presence of Escherichia coli. in fermented milk products sold within Maiduguri, Borno State. Thirty (30) samples were collected from different sources Bacteriological isolation and biochemical characterization yielded Escherichia coli and the prevalence of E. coli was 3.33 % (2/60). Antibacterial susceptibility test was carried out and the bacteria were sensitive to ciprofloxacin (17 mm) and gentamycin (21 mm), while the remaining antibiotics were non sensitive, i.e. cephalexin, cefoxitin and suphamethoxazole-trimethoprim. Based on EUCAST the isolates were resistant to all the antibiotics except gentamycin. The result revealed the presence of Escherichia coli in the fermented cow milk samples. The finding indicates possible faecal contamination of the milk product with serious public health consequences. This necessitates the need to screen other milk products in the area. Health authorities in the state need to enlighten dairy product farmers on the zoonotic potential of Escherichia coli.
