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.

柠檬香精油在控制狗口腔细菌方面的体外试验和干宠物饲料。

本研究的目的是评估柠檬香蒲精油对从狗口腔中分离出来并直接用于人工污染饲料的细菌的抗菌活性。狗口腔中流行的细菌接种在商品干狗饲料中，柠檬香精油通过喷雾沉积在饲料中。总共获得了 42 个分离菌株，其中 38 个革兰氏阳性，4 个革兰氏阴性。葡萄球菌是狗口腔中最常见的细菌（76.2%）。分离出的细菌对不同的抗菌药具有很高的耐药性。能够抑制口腔细菌的最低抑菌浓度为 0.38 毫克/毫升。柠檬香精油在饲料中的应用显示出显著的抑菌效果，这表明有必要进行进一步研究，以便将其用于控制动物饲料传播的病原体。

期刊介绍： Foodborne Pathogens and Disease is one of the most inclusive scientific publications on the many disciplines that contribute to food safety. Spanning an array of issues from "farm-to-fork," the Journal bridges the gap between science and policy to reduce the burden of foodborne illness worldwide. Foodborne Pathogens and Disease coverage includes: Agroterrorism Safety of organically grown and genetically modified foods Emerging pathogens Emergence of drug resistance Methods and technology for rapid and accurate detection Strategies to destroy or control foodborne pathogens Novel strategies for the prevention and control of plant and animal diseases that impact food safety Biosecurity issues and the implications of new regulatory guidelines Impact of changing lifestyles and consumer demands on food safety.
