GC-MS analysis of the fixed oil from Sus scrofa domesticus Linneaus (1758) and antimicrobial activity against bacteria with veterinary interest.

Abstract

The bioprospection of zootherapeutic products can be a source of new drugs and to the creation of new strategies of natural resources conservation and management of endangered species. This fact is supported by ethnobiological studies indicating that the usage of zootherapeutic products can be replaced by the use of natural products isolated from plants and domestic animals. The emergence of antibiotic-resistant bacteria has increased the need for research for new active principles. Ethnoveterinary studies in Brazil have shown that Sus scrofa domesticus fat is used for diseases associated with bacterial pathogens. The objective of this study was to identify the chemical composition and to evaluate the antibacterial activity of the fixed oil of Sus scrofa domesticus (OFSC) when used alone or associated with antibiotics. In the analysis of the oil composition, there were 4 constituents identified, with oleic acid being the major constituent. The OFSC did not present antibacterial activity when tested alone; however, it showed synergism in the modulating activity when associated with antibiotics Amikacin and Amoxicillin.
