Line 32: Line 32:  
The epidemiology and pathogenesis of many strongyle infections of grazing animals are very similar. Infection by ingestion of an infective larva (L3), development to L4 and adult stages is generally restricted to gastric or intestinal mucosa (although a few species migrate around the body), adult worms eventually emerge to lie on the mucosal surface. The prepatent period is normally 2 weeks, although it may be >6 months for certain species or if development is "arrested".
