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.
