Pronunciation: e-sof'a-gos'to-mum

Definition: A genus of strongyle nematodes (subfamily Oesophagostominae) that encyst in the intestinal wall of herbivores and primates, causing nodular disease. Larvae appear to stimulate a host reaction in the intestinal wall, forming nodules in which the worms complete their development (unless the host is immune); they then leave the nodule and feed as adults in the lumen of the large intestine.

[G. oisophagos, gullet (esophagus), + stoma, mouth]
