Abstract Context Fructus Meliae toosendan extracts (FMTE) have a good therapeutic effect on coccidiosis, but there is no relevant research on its prophylactic effect on coccidiosis. Objective This study comprehensively evaluates the anticoccidial effect of FMTE. Materials and methods In vitro, the unsporulated oocysts were treated with serial dilutions of FMTE and incubated for 7 d, and the sporulated oocysts were counted for calculating the median lethal concentration (LC50) of FMTE. In vivo, 180 10-day-old broiler chickens free of coccidiosis were weighted and randomly distributed into six groups: normal group, untreated group, 4 protective groups (positive group and three FMTE groups). From day 10 to day 21, chickens in the three FMTE groups were pre-treated with FMTE at the dosage of 2.5, 5 and 10 g/kg/d, respectively, and chickens in the positive group were pre-treated with qiuliling (10 g/kg/d). On day 14, chickens in all groups except the normal group were orally infected with 1.5 × 104 sporulated oocysts. The clinical symptoms were observed from day 10 to day 21, the anticoccidial index (ACI), tissue lesions, and intestinal microflora were determined on day 21. Results FMTE showed anti-sporulation effect against E. tenella and the LC50 value was 245.83 µg/mL in vitro. In vivo, FMTE at the dosage of 10 g/kg/d was effective against E. tenella infection, and its ACI value was 162.56, which was higher than the value of positive drug qiuliling (128.81). Discussion and conclusions: FMTE have potent anticoccidial effects, and it presents an alternative anticoccidial agent for avian coccidiosis control.

楝子提取物对艾美球虫的抗球虫作用

摘要 背景楝楝提取物(FMTE)对球虫病有良好的治疗作用,但对其防治球虫病的作用尚无相关研究。目的本研究综合评价FMTE的抗球虫作用。材料和方法 在体外,未孢子化的卵囊用 FMTE 的系列稀释液处理并孵育 7 天,并对孢子化的卵囊计数以计算 FMTE 的中位致死浓度 (LC50)。在体内,将180只10日龄无球虫病肉鸡称重,随机分为6组:正常组、未处理组、4个保护组(阳性组和3个FMTE组)。从第 10 天到第 21 天,三个 FMTE 组的鸡分别以 2.5、5 和 10 g/kg/d 的剂量用 FMTE 进行预处理,阳性组鸡用秋葵灵(10 g/kg/d)预处理。第14天,除正常组外,各组鸡均经口感染1.5×104个孢子化卵囊。从第10天到第21天观察临床症状,第21天测定抗球虫指数(ACI)、组织病变和肠道菌群。 结果FMTE对球虫具有抗孢子形成作用,LC50值为245.83 μg/毫升体外。在体内,10 g/kg/d剂量的FMTE对E. tenella感染有效,其ACI值为162.56,高于阳性药物秋立灵的值(128.81)。讨论和结论: FMTE 具有有效的抗球虫作用,为控制禽球虫病提供了一种替代的抗球虫剂。第14天,除正常组外,各组鸡均经口感染1.5×104个孢子化卵囊。从第10天到第21天观察临床症状,第21天测定抗球虫指数(ACI)、组织病变和肠道菌群。 结果FMTE对球虫具有抗孢子形成作用,LC50值为245.83 μg/毫升体外。在体内,10 g/kg/d剂量的FMTE对E. tenella感染有效,其ACI值为162.56,高于阳性药物秋立灵的值(128.81)。讨论和结论: FMTE 具有有效的抗球虫作用,为控制禽球虫病提供了一种替代的抗球虫剂。第14天,除正常组外,各组鸡均经口感染1.5×104个孢子化卵囊。从第10天到第21天观察临床症状,第21天测定抗球虫指数(ACI)、组织病变和肠道菌群。 结果FMTE对球虫具有抗孢子形成作用,LC50值为245.83 μg/毫升体外。在体内,10 g/kg/d剂量的FMTE对E. tenella感染有效,其ACI值为162.56,高于阳性药物秋立灵的值(128.81)。讨论和结论: FMTE 具有有效的抗球虫作用,为控制禽球虫病提供了一种替代的抗球虫剂。从第10天到第21天观察临床症状,第21天测定抗球虫指数(ACI)、组织病变和肠道菌群。 结果FMTE对球虫具有抗孢子形成作用,LC50值为245.83 μg/毫升体外。在体内,10 g/kg/d剂量的FMTE对E.tenella感染有效,其ACI值为162.56,高于阳性药物秋立灵的值(128.81)。讨论和结论: FMTE 具有有效的抗球虫作用,为控制禽球虫病提供了一种替代的抗球虫剂。第10天至第21天观察临床症状,第21天测定抗球虫指数(ACI)、组织病变和肠道菌群。 结果FMTE对球虫具有抗孢子形成作用,LC50值为245.83 μg/毫升体外。在体内,10 g/kg/d剂量的FMTE对E. tenella感染有效,其ACI值为162.56,高于阳性药物秋立灵的值(128.81)。讨论和结论: FMTE 具有有效的抗球虫作用,为控制禽球虫病提供了一种替代的抗球虫剂。FMTE剂量为10 g/kg/d时对E. tenella感染有效,其ACI值为162.56,高于阳性药秋立灵的值(128.81)。讨论和结论: FMTE 具有有效的抗球虫作用,为控制禽球虫病提供了一种替代的抗球虫剂。FMTE在10 g/kg/d剂量下对E.tenella感染有效,其ACI值为162.56,高于阳性药物秋立灵的值(128.81)。讨论和结论: FMTE 具有有效的抗球虫作用,为控制禽球虫病提供了一种替代的抗球虫剂。
