[Clinical, parasitological and serological investigations in sarcosporidiosis (sarcocystis suihominis) of man (author's transl)].

Eight medical students ate for a test raw meat from a pig experimentally infected with sporocysts of Sarcocystis suihominis. The meat had been officially controlled before and was found free of Trichinella and qualified for consumption. 6 to 24 hours after the meal all persons suffered from acute clinical symptoms, above all diarrhoea and vomiting, coldness and sweating which decreased, however, within 12 to 24 hours. Clinical-chemical investigations made during this time suggested an acute infection combined with an exsiccosis; the specificity of the infection, however, could only be established by serological methods and by microscopical demonstration of sporocysts of the agent. The pathogenetic relations are discussed.
