Quick Summary:

  • Sarcocystosis is parasitic infection by Sarcocystis, affecting mammals, specifically humans and livestock. The parasite typically gets ingested with raw or undercooked meat, such as beef and pork
  • Sarcocystosis is a versatile and prevalent parasitic infection. It is most common in Europe, Asia, and North and South America
  • The parasite works via a two host mechanism - the definitive and intermediate hosts
    • The definitive host of Sarcocystosis, the host that is responsible for sexual replication of the parasite, is humans
    • The intermediate host, the host that allows facilitated infection of the definitive host, is livestock, most often cattle and swine
  • In most cases, the infection is asymptomatic. However, some individuals may develop symptoms very rapidly upon infection. Nausea, abdominal pain, diarrhea and vomiting are the most common symptoms; these may occur as little as six hours after infection
  • Sarcocystosis infection can be diagnosed via confirmation of eggs in a stool sample upon examination, along-with observation of the presenting symptoms
  • There are no known medical or therapeutic treatments for Sarcocystosis, although anti-parasitic drugs have been shown to shorten the duration of infection in some cases
  • Cooking meat thoroughly may help prevent infection by Sarcocystis. If infection occurs, it generally resolves spontaneously, in a majority of cases
