The first event in the infection process of Ostertagia ostertagi in cattle is the process of exsheathment. Before trichostrongylid nematodes can transition from a free-living infective stage larva (L3) on pasture to a parasitic existence within the ruminant host, it must first undergo exsheathment. Exsheathment is the process whereby the L2 cuticle retained from the previous molt is cast from the L3. Exsheathment enables the developmental transition from a free-living stage on pasture to a parasitic existence in the bovine host. For those species with a predilection site in the abomasum, such as O. ostertagi, …
