Prevalence and antimicrobial resistance of bacteria isolated from Beni-Guil lamb carcasses in eastern Morocco

This study aims to assess the microbial quality and antimicrobial resistance of bacteria isolated from Beni-Guil lamb carcasses. 103 samples were used for the study. The mean values obtained for microbial quality were 4.65, 3.07, 1.26, 0.99 and 0.69 (log10 CFU/cm 2 ), respectively for total aerobic Flora counts, Enterobacteriaceae, fecal coliform, Escherichia coli and Staphylococcus aureus.70% of tested Escherichia coli strains were resistant to gentamicin and ciprofloxacin, as for Staphylococcus aureus, 100% of strains tested were resistant to ciprofloxacin and sensitive to erythromycin. Regarding gentamicin and benzylpenicillin, 70 % and 60% of Staphylococcus aureus strains were resistant, respectively.
