Evaluación in vitro de la resistencia antimicrobiana en Campylobacter termotolerantes presentes en planta de faena aviar.

Abstract

Considering that thermotolerant Campylobacter (TC) is a zoonotic agent of great relevance in food safety and, therefore, in public health, this work was carried out with the objective to determine phenotypically, the antimicrobial resistance profile of TC isolated from different stages of the broiler slaughter process. We worked with a collection of TC isolates (n = 102), which were obtained during 2015 from samples taken at different stages of the slaughter process of broiler chickens. The minimal inhibitory concentration of the isolates was evaluated against fluoroquinolones (ciprofloxacin –CIP- and enrofloxacin –ENR-). From the epidemiological point of view, 90% of the C. jejuni isolates and 100% of the C. coli isolates showed decreased susceptibility to CIP. From a clinical point of view, 81% of the C. jejuni and 100% of the C. coli isolates were resistant to this antimicrobial. In the case of ENR, 76% of the C. jejuni strains and 88% of the C. coli strains showed resistance. In addition, 2% of the C. jejuni and 12% of C. coli isolates showed intermediate resistance to ENR. The identification of a high proportion of TC strains clinically resistant to CIP and ENR threatens the efficacy of antimicrobial therapy against the clinical treatment of campylobacteriosis. It is necessary to strengthen the TC surveillance and control, promoting integration between the laboratory, human clinic and veterinary areas.
