Occurrence of antibiotic resistant enteric Escherichia coli in marketed chicken in Ibadan metropolis, Southwest Nigeria

Abstract: 

In most developing countries including Nigeria, indiscriminate use of antibiotics in food animals could be incriminated as a critical factor leading to antimicrobial resistance. Intestines from marketed chicken in fifteen market locations in Ibadan metropolis were randomly sampled to examine for antibiotic resistant enteric bacteria to some commonly used antibiotics. Bacteriological examination of intestinal samples was done using standard methods, followed by in-vitro antibiotic sensitivity test by agar gel diffusion technique. The enteric bacteria, Escherichia coli that were multi-drug resistant to different combinations of aminoglycosides, cephalosporins and fluoroquinolones group of drugs were isolated. The intestines were also noticed being scavenged on by animals and collected by some small hold farmers to feed their animals. These commensal bacteria present in fresh marketed chicken may serve as reservoirs for resistant genes that could potentially be transferred to pathogenic organisms in animals and humans. Thus, the occurrence of antibiotic resistance in enteric bacteria isolated from marketed chicken in Ibadan metropolis calls for veterinary and public health concern, and may suggest a potential involvement in the occurrence of resistance food-borne pathogens in the study area. Therefore, responsible therapeutic use of antibiotics against infections should follow appropriate diagnosis and antibiotic susceptibility assessments.
