Antibiotic Resistance and Potential Pathogenicity of an Isolate iSalmonella enterica enterica/iBased on Genomic Comparison with of 103 and 2199 Strains Obtained from Contaminated Chicken Meat in Mexico

摘要

The strategies implemented to identify pathogenic strains of Salmonella in countries with high production and consumption when is of chicken meat [such as Mexico), successfully bring germ-free meat to the market. Two Salmonella enterica enterica strains obtained from Mexican chicken meat were completely sequenced. The genomic comparison with the CT18 Salmonella strain indicates that strains 103 and 2199 vary by 1.9%. Genome analysis of the isolated strains revealed the presence of numerous virulence genes, as well as antibiotics resistance genes in these two isolates. Their potential pathogenicity was inferred from presence of 22 (103 strains) and 19 genes (2199 strains) homologous to the one annotated in Salmonella enterica virulome databanks. The characterization of these strains will contribute to successful Salmonella monitoring in Mexico.
