Antimicrobial resistance genes in bacteria from animal-based foods.

Antimicrobial resistance genes in bacteria from animal-based foods. Adv Appl Microbiol. 2020;112:143-183 Authors: de Alcântara Rodrigues I, Ferrari RG, Panzenhagen PHN, Mano SB, Conte-Junior CA Abstract Antimicrobial resistance is a worldwide public health threat. Farm animals are important sources of bacteria containing antimicrobial resistance genes (ARGs). Although the use of antimicrobials in aquaculture and livestock has been reduced in several countries, these compounds are still routinely applied in animal production, and contribute to ARGs emergence and spread among bacteria. ARGs are transmitted to humans mainly through the consumption of products of animal origin (PAO). Bacteria can present intrinsic resistance, and once antimicrobials are administered, this resistance may be selected and multiply. The exchange of genetic material is another mechanism used by bacteria to acquire resistance. Some of the main ARGs found in bacteria present in PAO are the bla, mcr-1, cfr and tet genes, which are directly associated to antibiotic resistance in the human clinic.
