ASSESSMENT OF ANTIMICROBIAL RESISTANCE OF ESCHERICHIA COLI ISOLATED FROM BROILER CHICKEN IN COMMERCIAL POULTRY FARM AT IDO LOCAL GOVERNMENT AREA IN OYO STATE
Abstract
Antimicrobial resistance (AMR) in Escherichia coli (E. coli) poses a significant threat to public health, particularly within the poultry industry. This study evaluates the antimicrobial resistance pattern of E. coli isolated from broilers in commercial farms located in Ido Local Government, Oyo State, using a cross-sectional analytical design. Ten commercial broilers farms were visited and samples were collected from six birds’ Cloaca swabs, per farm using random sampling methods. Cloaca swabs were collected using swab sticks and samples were transferred instantly to the laboratory for microbial analysis. The samples were cultured using the streak plate method to identify E. coli strains. Result show that 20 cloacal swabs was obtained and 10(50%) was positive. Antimicrobial susceptibility testing was conducted using the disc diffusion method on a range of antibiotics, including there is 40% AMR to streptomycin, 20% to ciprofloxacin and ceftriaxone, 0% to Gentamycin, Enrofloxacin, Amoxicillin, Florfenicol, Doxycycline, Tetracycline and Colistin in Ido Local Government Area to E. coli isolates. A survey component was incorporated to evaluate and assess the biosecurity practices of the poultry farms. This study revealed that E. coli sourced from poultry farms shows higher resistance to streptomycin, ciprofloxacin and ceftriaxone, except Gentamycin, Enrofloxacin, Amoxicillin, Florfenicol, Doxycycline and Tetracyclin. This can be mitigated by cleaniness, proper manufacturing practices and strict biosecurity measures. This study contributes valuable data to the understanding of AMR in E. coli among poultry in Nigeria, Highlighting the implications for both animal and human health.
