Concurrent Infection of Oesophagostomum species in a Slaughtered Goat: A Case Report

The morbidity and mortality of gastrointestinal nematodes in goats made them one of the most significant parasites in the world, causing huge economic loss for farmers. It has been reported that the economic loss due to gastrointestinal parasitism was Rs. 372.35 per goat annually. In the present study, the intestinal sample was collected from a local slaughter house at Izatnagar, Bareilly, Uttar Pradesh, for screening the gastrointestinal nematodes. Initially, the pathological lesions like nodules, cyst and haemorrhagic patches etc. were examined for any parasitic infection. The found worms in the intestinal content were subjected for microscopic examination for the identification of the nematode and identified them as Oesophagostomum spp. based on buccal capsule with cephalic and cervical structures. Interestingly, both Oesophagostomum columbianum and O. asperum species were found in the same sample. The male and female Oesophagostomum species were also differentiated by examining the spicule and gubernacular length, position of the vulva and anus. This study reports the infection of Oesophagostomum spp. in a goat and the first case report of concurrent infection of O. columbianum and O. asperum in the Bareilly region of Uttar Pradesh.
