Trichuris globulosa (cattle)



Untitled document

Nematode (order Enoplida)


Distribution: widespread. 

Host: None has been attributed to natural Trichuris infection in cattle.

Life Cycle: Direct roundworm life cycle in cecum. Infective larvae develop within eggs after at least 3 weeks on pasture. These are resistant to cold temperatures and drying, so may remain infective for several years. Animals are infected by ingesting embryonated eggs. Adults develop in 1 to 3 months. 

Diagnosis:  Long roundworms; the front or anterior part is long and thin while the posterior is much thicker, giving the appearance of a whip. Posterior of male is curled. Barrel-shaped eggs are seen in feces.

Clinical features: Whipworms are widespread, but effects of infection have not been determined. 

Control: Treatment of cattle with an anthelmintic is most effective. Pasture management is also useful.
