Determinación de la resistencia a antibióticos mediante tres métodos fenotípicos en cepas de <i>Campylobacter coli</i> aisladas de carne de pollo comercializada en Lima, Perú

Motivation for the study. Campylobacter coli, a bacterium that causes gastroenteritis in humans through the consumption of contaminated chicken meat, has shown an increase in antibiotic resistance worldwide. In Peru, information on this is scarce, so we proposed to determine resistance and minimum inhibitory concentration (MIC) using three phenotypic methods. Main findings. In all methods, more than 70% of strains were multidrug resistant with a MIC ≥32 μg/mL, with plate microdilution being the most efficient method. Implications. C. coli strains from chicken carcasses had a high percentage of multidrug resistance. Continuous monitoring with a multisectoral approach encompassing human, animal, and environmental health is necessary.
