BERMUDEZ D, Paula M  y  RINCON G, Sandra M. Evaluation of Antimicrobial susceptibility of Salmonella spp. strains isolated from Pork Carcasseson Colombia. Rev. Fac. Nac. Salud Pública [online]. 2014, vol.32, n.1, pp.88-97. ISSN 0120-386X.

OBJECTIVE: this study was aimed to establish the patterns of antimicrobial resistance in 155 strains of Salmonella spp. isolated from pig carcasses in slaughter house in Colombia. METHODOLOGY: using the disc diffusion method (Bauer & Kirby, 1966) we evaluated nine antibiotics: 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) and tetracycline (30 ug). RESULTS: the results confirm the presence of multiresistant strains of Salmonella spp. in pig slaughter house, showing 30 different patterns of multidrug resistance, the most common was ampicillin, amoxicillin, chloramphenicol, florfenicol and tetracycline in 16.77% (n = 26) strains. Tetracycline and florfenicol were less effective with 94.84% (n = 147) and 47.74% (n = 74) of the resistant strains, respectively. DISCUSSION: it must consolidate monitoring programs and surveillance and control systems to prevent the spread of multiresistant strains in foods of animal origin, with an approach of supply chain of pork, as an essential element of food safety system in Colombia.
