Life Cycle:

Life cucle direct and monmoxenous with microbivorous juvenile stages, typical of Trichostronglyloidea.

 Eggs, produced by females feeding in host intestine, are passed through host feces and hatch in the fecal pat The first stage larvae (L1) feed on soil and fecal bacteria. Two subsequent molts to L2 and L3 are completed between 24 and 36 hours.

The infective L3 larvae do not feed and are enclosed in a sheath composed of the retained L2 cuticle. They migrate from the fecal pat into grasses, where they develop and become infectious in 1 to 6 weeks.

In the host, the L3 larvae exsheath, move into mucosa of the small intestine, and undergo the third and fourth molts to L4 and L5 larvae. When sexually mature adults mate. Ferilized females produce eggs, and the cycle repeats (Albrechtova et al., 2020).
