[Experimental infection in man and monkey (Cercopithecus callitrichus) by sarcosporidian cysts of cattle and swine].
Reported in this paper is experimental sarcosporidial infection of man and lower primates (grass monkey). The courses of infection were followed up by coprological and serological tests. Oral-alimentary administration of 100 Sarcocystis (S.)-fusiformis cysts obtained from cattle muscle caused patent infection in man. Gastro-intestinal symptoms developed in one of the probands, between five and seven days after infection. No sporocysts were detectable from the stools of seven probands who had consumed 200 g each of commercially available minced pork which contained small amounts of Sarcocystis miescherania villi. Rise in antibody to Sarcocystes following infection was detected however, by means of indirect fluorescence antibody reaction (IFAR). Gastrointestinal complaints were reported by one of the probands, one day after infection. No sporocysts were detectable from the stools of four grass monkeys, following oral-alimentary administration of 50 or 25 S. miescherania cysts, but rise in antibody to S. miescherania was recorded in these cases. Those grass monkeys which had received 50 cysts responded by exhibiting, after infection, severe clinical phenomena with intestinal signs and symptoms of the central nervous sytem.
