BERMUDEZ, P. M; PULECIO, S. L y SUAREZ, M. C. ANTIMICROBIAL SUSCEPTIBILITY OF Salmonella enterica STRAINS ISOLATED FROM FLOORS, EQUIPMENT, MACHINERY, AND FINISHED PRODUCT IN PORCINE SLAUGHTERHOUSES IN COLOMBIA. Rev. Med. Vet. Zoot. [online]. 2016, vol.63, n.1, pp.39-53. ISSN 0120-2952. https://doi.org/10.15446/rfmvz.v63n1.56903.
The development and spread of antimicrobial multidrug resistance_of Salmonella spp. from food chain is a public health concern global. This study aimed to describe the antimicrobial resistance patterns of 283 isolates of Salmonella enterica from pork slaughterhouse in Colombia. Antimicrobial susceptibility on ten antimicrobials was evaluated: amoxicillin - clavulanic acid (30 ug), ampicillin (10 ug), ceftiofur (30 ug), ciprofloxacin (5 ug), chloramphenicol (30 ug), florfenicol (30 ug), gentamicin (10 ug), sulfadiazine/trimethoprim (25 ug), tetracycline (30 ug) and tilmicosin (15 ug) using the disc diffusion method. The results showed the high presence of isolates multidrug resistant of Salmonella enterica widespread on environmental of slaughterhouse (46.64% n: 132). 52 multidrug resistance patterns were detected. The most common was ceftiofur - tetracycline - tilmicosin in 9.89% (n = 28) of isolates. These same three antimicrobials were less effective with 96.82 % (n = 274) resistant-isolates against tetracycline, 73.14 % (n = 207) against tilmicosin and 28.27 % (n = 80) against ceftiofur. Of particular concern was the high rate of resistance to ceftiofur due to its cross-resistance to ceftriaxone. The results demonstrate the need to promote and strengthen an official Integrated Program for Antimicrobial Resistance Surveillance and volunteer monitoring systems in each link of the porcine production chain, to contribute to the prevention and control of food-borne infections in the context of safety management system in Colombia.
