fecal examination

Infection may be diagnosed on clinical signs and fecal examination.

Dogs should have fecal examinations and deworming as necessary.

Human echinostomiasis can be diagnosed through the recovery of eggs through a fecal examination.

Therefore despite the inherent limitations, fecal examination is the only practicable way of collecting data on parasites.

Necropsy of clinical cases of trichuriasis may be necessary to validate a diagnosis, since clinical signs may develop prior to patency, thus inhibiting diagnosis by fecal examination alone.
