| Résumé: | Tetracyclines and sulfonamides are broad-spectrum antibacterial agents which have been used to treat bacterial infections for over half a century. The widespread use of tetracyclines and sulfonamides led to the emergence of resistance in a diverse group of bacteria. This resistance can be studied by searching for resistance genes present in the bacteria responsible for different resistance mechanisms. <i>Salmonella</i> is one of the leading bacteria causing foodborne diseases worldwide, and its resistance to tetracyclines and sulfonamides has been widely reported. The literature review searched the Virtual Health Library for articles with specific data in the studied samples: the resistance genes found, the primers used in PCR, and the thermocycler conditions. The results revealed that <i>Salmonella</i> presented high rates of resistance to tetracycline and sulfonamide, and the most frequent samples used to isolate <i>Salmonella</i> were poultry and pork. The tetracycline resistance genes most frequently detected from <i>Salmonella</i> spp. were <i>tetA</i> followed by <i>tetB</i>. The gene <i>sul1</i> followed by <i>sul2</i> were the most frequently sulfonamide resistance genes present in <i>Salmonella</i>. These genes are associated with plasmids, transposons, or both, and are often conjugative, highlighting the transference potential of these genes to other bacteria, environments, animals, and humans. |
