Análisis de la diversidad de resistomas y virulomas en un matadero a lo largo de la cadena de producción de la carne

Resumen

In this study, resistome and virulome patterns were determined, in order to monitor the possible contamination along the meat production chain. By means of culture-dependent and independent methods (metagenomics), high levels of microbial contamination were detected on surfaces of both animals and processing areas. In addition, a great diversity and abundance of antibiotic resistance genes (ARGs) and virulence determinants (VRGs) were obtained, which represents a potential risk for public health. Subsequently, the microbial ecology and the functional genes abundantly associated with stress genes were determined, especially in the first production areas (most contaminated areas). And to prevent the spread of microbial contaminants and their resistance / virulence genes, the HLE disinfectant was used, which performed best when combined with a pre-cleaning with detergent.
