Antibiotic Resistance of Stenotrophomonas maltophilia Strains Isolated from Horses

Abstract

Stenotrophomonas maltophilia is a member of gamma proteobacteria that has been frequently isolated from humansas well as from animals. One of the most outstanding feature of S. maltophilia is its antibacterial resistance that isbasicly controlled by various pathways including intrinsic manner. By this study we aimed to evaluate theinteraction of S. maltophilia suspected equine strains with various antibiotics in the presence of Thymoquinone invitro. Disc diffusion technique was used for measuring interactions between the thymoquinone and others. Nomeasurable inhibition zone for synergistic or antagonistic effect between the thymoquinone and test antibioticswas observed. However, the thymoquinone itself has an antibacterial potential.
