How can the disease be diagnosed?
Diagnosis of neonatal swine coccidiosis due to Isospora suis is based on clinical signs, herd history, and the confirmed presence of the parasite. The endogenous stages in the intestinal epithelium may be identified microscopically in mucosal scrapings. The faeces, however, should be examined for oocysts. The disease must be differentiated from nutritional imbalances and viral or bacterial infections.
