Pathogenic species associated with disease in cattle includes:
- Enterocytozoon bieneusi
Clinical signs are generally nonspecific for this parasite as up to 20% of most dairy herds are usually infected asymptomatically. Symptoms are usually associated with pre-existing diarrhea caused by other agents such as bovine viral diarrhea or coccidiosis. This parasite is often seen in young weaned beef and dairy calves.
Diagnosis is usually based on laboratory identification of Enterocytozoon spp by ELISA or PCR assays.
