A parasite of swine worldwide
Swine
Gastro-intestinal parasites
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).
