    摘要:

    食道口线虫主要寄生于牛、羊的结肠和肠腔内,在中国各地牛、羊中普遍存在。感染动物表现为弓腰、腹痛和顽固性下痢,剖检可见结肠肠壁结节、肠壁破溃甚至腹膜炎。饱和食盐水漂浮法可检测到淡黄色椭圆形虫卵,根据临床症状和虫卵形态特征可以初步诊断。病理剖检发现,肠壁结节和PCR检测可以确诊。食道口线虫引起肠管病变导致其不能制作肠衣,从而降低畜牧业经济效益,可通过避免在清晨、傍晚放牧,牛、羊粪便无害化处理、保持饲草和饮水卫生等手段综合防制本病。

    Abstract:

    Oesophagostomum mainly parasitize the colon and intestinal lumen of cattle and sheep,and are widely prevalent in cattle and sheep across various parts of China.Infected animals exhibit symptoms such as hunchback,abdominal pain,and stubborn diarrhea.Autopsy reveals colonic wall nodules,intestinal wall rupture,and even peritonitis.Saturated saltwater floating method can detect pale yellow oval eggs,which can be preliminarily diagnosed based on clinical symptoms and egg morphology characteristics.Pathological autopsy reveals intestinal wall nodules and PCR testing can confirm the diagnosis.Oesophagostomum can cause intestinal lesions,leading to the inability to make intestinal casings and reducing the economic benefits of animal husbandry.o prevent and control this disease,a comprehensive approach can be adopted,including avoiding grazing during early morning and evening,treating cattle and sheep manure to ensure it is harmless,and maintaining hygiene in forage and drinking water.
