Antibiotic resistance of Latilactobacillus sakei lactic acid bacteria

Antimicrobial resistance represents a serious threat to public health due to such negative consequences as the difficulty of treating certain diseases, higher mortality, and increased medical costs. Transmission through food chains is known to be one of the most important routes for the spread of antibiotic-resistant bacterial strains. According to scientific publications, lactic acid bacteria can serve as a reservoir for the transmission of antibiotic resistance genes. In this regard, it is important to study the antibiotic resistance of lactic acid bacteria strains used in food industry, particularly those not subjected to heat treatment prior to consumption. In this article, we investigate the resistance of Latilactobacillus sakei lactic acid bacteria to antibacterial preparations by a disk diffusion susceptibility test. The strains under study were not resistant to most of the antibiotics considered. The DSM 20017 strain, which was sensitive to all tested preparations, showed the least resistance to antibiotics. Other strains also demonstrated sensitivity to most of the studied antibacterial preparations, although with an intermediate sensitivity to certain antibiotics. Further research is required for a comprehensive characterization of the phenotypic resistance of Latilactobacillus sakei bacteria to antibiotics.
