ABSTRACT: Meat of bovine origin is one of the main vectors for the transmission of Escherichia coli to human consumers. This pathogen can cause serious human illness. Objective: The objective of this study was to characterize the resistance phenotype of Escherichia coli isolates isolated from bovine dung in the Abidjan district. Methods: A total of 336 cattle dung samples were analyzed and 23.80% (80/336) were positive for Escherichia coli. Results: The most common phenotypic resistances detected were 42.9% for nalidixic acid, 33.3% for amoxicillin, 30% for amoxicillin/clavulanic acid, 25% for enrofloxacin, 20% respectively for cefepime and trimethoprim-sulfamethoxazole. However, no resistance was observed to ticarcillin, ceftazidime, gentamicin and amikacin. In total, 70% (56/80) of isolates were resistant to at least three (3) antibiotic families, and 20% (16/80) were resistant to at least four (4) families. These results suggest that Escherichia coli isolates from bovine faeces are significantly diverse in terms of antibiotic resistance. Conclusion: the gastrointestinal microflora of cattle could be an important reservoir of various determinants of antimicrobial resistance, which is potentially dangerous for public health.
