Prevalence of Extended Spectrum Beta-Lactamase-Producing <i>Escherichia coli</i> in Broiler Chickens in Yaoundé Capital City of Cameroon

Background: Escherichia coli are ubiquitous bacteria colonising both humans and animals. Extended spectrum β-lactamase-producing E. has been selected as a suitable indicator for the monitoring surveillance of antimicrobial resistance. Death due to resistant is continuously rising in Cameroon, but contribution aviary sector not well studied. Therefore, this study aimed investigate resistance profile extended beta-lactamases-producing strains, isolated from faeces broiler chickens Yaoundé, capital city Cameroon. Methods: A cross-sectional descriptive was carried out February June 2020. were samples broilers poultry farms Yaoundé submitted β-lactamase screening. The logistic regression used assess statistical association significance threshold p-value 0.05. Results: Out 385 faecal collected farms, 114 isolates obtained which 30 (26.32%) Spectrum Beta-Lactamases-producing coli. These revealed high all antibiotic families. Poor storage conditions feeds proximity latrines, troughs on ground, lack foot bath uniforms, inadequate treatment faeces, poor usage preventive antibiotics water have identified risk factors carriage ESBL-producing Conclusion: This work reveals emergence failure biosecurity system. As such, awareness breeders respect measures may be an effective tool tackle resistance, specifically livestock industries using One Health approach.
