Case Report: Sarcocystosis in a Sheep

Sarcocystis gigantea infection was confirmed in a 6-year-old sheep slaughtered in Brazil, with multiple macrosarcocysts found in the esophagus, pharynx, tongue, and diaphragm. Gross, histologic, and molecular analysis identified S. giganteaas the causative protozoan. While non-zoonotic and often subclinical, visible muscle cysts lead to carcass condemnation, posing significant economic losses to the sheep meat industry.
