Evaluación de antibiorresistencia en bacterias grampositivas aisladas en carne de pollo que se expende en el cantón Ambato, provincia de Tungurahua

Abstract

The present investigation was carried out with the main purpose of evaluating the antibacterial resistance in Gram positive bacteria (Vagococcus lutrae, Mammaliicoccus sciuri and Kurthia gibsonii) isolated in chicken meat sold in Ambato Canton, province of Tungurahua, because bacterial resistance to antibiotics is a specific aspect of the natural evolution of bacteria, The study was carried out with strains of (Vagococcus lutrae, Mammaliicococcus sciuri and Kurthia gibsonii) that were isolated and molecularly identified from chicken meat sold in the canton of Ambato from previous investigations, which are kept in the Laboratory of Microbiology and Molecular Biology of the Faculty of Agricultural Sciences of the Technical University of Ambato. It was found that there is the presence of antibioresistance in gram-positive bacteria, specifically in strains of Vagococcus lutrae, Mammaliicoccus sciuri and Kurthia gibsonii, isolated from samples of chicken meat marketed in the Ambato Canton, province of Tungurahua. Likewise, the results obtained by the agar diffusion method revealed significant patterns of antibiotic resistance in the Gram-positive bacteria studied. Resistance profiles against various antibiotics used in both Veterinary and Human Medicine were identified, highlighting the importance of addressing resistance in an interdisciplinary context and the analysis of virulence factors in strains of Vagococcus lutrae, Mammaliicococcus sciuri and Kurthia gibsonii provided valuable information on the possible risks associated with these bacteria in chicken meat.
