The antimicrobial action of palm oils containing medium-chain fatty acids against gram-positive bacteria associated with mastitis in dairy cattle: in vitro study

Popis výsledku v původním jazyce

Gram-positive bacteria belonging among ubiquitous group of pathogens that are able to induce mastitis in dairy cattle herds are potential threat for not only animals, but also human communities since they have been known for their increasing resistance to commonly used on-farm-disinfections and antibiotics. Thus, the need for alternatives is necessary and naturally occurring substances, such as palm oils rich in medium-chain fatty acids (MCFAs), which are known for their antibacterial activity, can serve as a substitution. Coconut, palm kernel, and tucuma oil are the regular constituents of both human and animal nutrition. Therefore, the aim of this study was to evaluate the in vitro inhibitory activity of palm oils rich in MCFAs, after cleavage by an exogenous lipase from Mucor javanicus, against five strains of Gram-positive bacterial pathogens proven to cause mastitis in dairy cattle (Staphylococcus aureus and Streptococcus agalactiae) by the broth microdilution method. Tested palm oils showed growth-inhibitory effect against all tested bacterial strains in the range of 64–8192 μl/ml. Str. agalactiae has been determined as more sensitive species, when compared to S. aureus. The results of the present study propose the idea that palm oils rich in MCFAs can serve as an alternative approach within the predip and postdip procedures in bovine mastitis control, but further in vivo studies are needed to confirm the findings for their possible practical usage.
