Resistencia antibiótica de entero bacterias de cobayos en sistemas de producción familiar-comercial de San José de Barabón

Abstract

What we know today as antibiotic resistance translates into the ability of a microorganism to resist the effects of antibiotics. Also, the improper use of these antibiotics by producers who supply them without diagnosis and in the wrong dosage promotes the emergence of resistant bacteria. It increases the problem of public and animal health worldwide. The objective of this study was to determine the pharmacological resistance of Enterobacteriaceae from case-positive guinea pigs in family-commercial production systems in the San José de Barabón community. The investigation was carried out in 15 farms with a total of 110 samples with rectal swabs from adult guinea pigs, where 22 samples were positive for Salmonella spp and Shigella spp; from these samples, antibiograms were performed with five replicates of each piece using the disc-plate or Kirby-Bauer diffusion technique on Muller-Hinton agar with antibacterial discs. The results obtained for Salmonella spp against the four antibiotics showed total resistance for Sulfamethoxazole+Trimetropim and partial resistance for Oxytetracycline, while for Shigella spp, the total resistance was for Oxytetracycline and partial resistance for Enrofloxacin and Tetracycline. In conclusion, providing technical advice through government agencies should be considered, emphasizing small producers. Their practices indirectly safeguard food security in rural areas and self-consumption, helping to prevent repercussions on the population's health.
