Abstract
The aim of this study was to evaluate the antibacterial activity of Cymbopogon citratus essential oil against bacteria isolated from the oral cavity of dogs and applied directly to artificially contaminated feed. The commercial dry dog feed received the inoculum of the bacteria prevalent in the oral cavity of the dogs where C. citratus was deposited in the feed by spray. In total, 42 isolates were obtained, 38 Gram-positive and 4 Gram-negative. Staphylococcus spp. was the most prevalent bacteria in the oral cavity of dogs (76.2%). The isolates showed high levels of resistance to different antimicrobials. The minimum inhibitory concentration capable of inhibiting oral bacteria was 0.38 mg/mL. C. citratus essential oil showed positive results with a significant bacterial reduction when applied to feed, signaling the need for further studies to enable its use in the control of pathogens transmitted by animal feed.
