Sarcocystosis is characterized by the invasion of various tissues by protozoa of the genus Sarcocystis. S. hominis (intermediate host domestic cattle) and S. suihominis (domestic pig) are the most significant to humans, to whom they are transmitted by ingestion of uncooked beef or pork. Camel meat can be a significant source of S. cameli in Arabia. Humans and other primates serve as either intermediate or final host: (1) intermediate host—presence of cysts in muscle is usually asymptomatic, but might cause myositis or myopathy; detected on clinical examination or muscle biopsy; (2) final host—can be asymptomatic or cause fever and gastrointestinal upset; oocysts or sporocysts can be detected in faeces. There is no specific treatment. Prevention is by not eating uncooked meat from any animal and by improving food hygiene in poorer countries.
