沙门氏菌能够危害人类和动物健康,多药耐药性(MDR)一直是一个公共健康问题。此外,在家禽生产中实施了无抗生素或减少抗生素的政策。因此,寻找抗生素替代品比以往任何时候都更加紧迫。本研究的目的是评估八角肉桂精油(SCEO)的体外抗菌活性及其对沙门氏菌感染的预防作用。沙门氏菌给,体内的肯塔基州沙门氏菌。结果表明,SCEO对鸡白癜风沙门氏菌有效,沙门氏菌给,和肯德基沙门氏菌在体外。补充SCEO可以显着降低鸡沙门氏菌和沙门氏菌的感染,虽然它可以轻微但不显著地减少肯塔基州沙门氏菌的感染,同时也显著减轻体重(BW)损失引起的感染鸡沙门氏菌,沙门氏菌给,黄鸡和肯塔基州沙门氏菌。SCEO对黄鸡沙门氏菌感染的预防效果最好,其次是鸡伤寒沙门氏菌感染和肯德基沙门氏菌感染。SCEO,用作抗生素替代品,可能是一种有效的预防鸡沙门氏菌感染的策略,沙门氏菌给,黄鸡和肯塔基州沙门氏菌。
Salmonella is capable of harming human and animal health, and its multidrug resistance (MDR) has always been a public health problem. In addition, antibiotic-free or antibiotic-reduced policies have been implemented in poultry production. Therefore, the search for antibiotic alternatives is more urgent than ever before. The aim of this study was to assess the antibacterial activity of star anise-cinnamon essential oil (SCEO) in vitro and its prophylactic effect against the infections of Salmonella pullorum, Salmonella give, and Salmonella kentucky in vivo. The results demonstrated that SCEO is effective against Salmonella pullorum, Salmonella give, and Salmonella kentucky in vitro. Supplementation with SCEO could significantly decrease the infections of Salmonella pullorum and Salmonella give, whereas it could slightly but not significantly decrease the infection of Salmonella kentucky, while also significantly alleviating the body weight (BW) loss caused by the infections of Salmonella pullorum, Salmonella give, and Salmonella kentucky in Yellow chickens. The SCEO had the best prophylactic effect against the infection of Salmonella give in Yellow chickens, followed by the infection of Salmonella pullorum and the infection of Salmonella kentucky. The SCEO, used as an antibiotic alternative, could be an effective prevention strategy against the infections of Salmonella pullorum, Salmonella give, and Salmonella kentucky in Yellow chickens.
