Abstract
Sarcocystosis infection is caused by protozoan cysts of genus Sarcocystis spp. where S. hominis, S. heydorni (bovines) and S. suihominis (porcine) are the most relevant for humans because of their zoonotic potential. S. cruzi, S. suihominis and S. ovicanis represent the most pathogenic species for cattle, pigs and sheep respectively. This infection has a worldwide importance due to its high transmission; besides to represent a zoonosis, it generates great economics losses. The main diagnostic methods for this disease are artificial digestion, PCR, indirect ELISA, and compression analysis. It’s important to highlight few studies on Sarcocystis spp., especially the ones involving the pursuit of effective treatments to control the infection for both humans and animals, however, some studies have reported that treatments such as cotrimoxazole and albendazole with or without prednisone are effective in counteracting symptoms in humans, considering the lack of reports about Sarcocystis spp. prevalence in Colombia.
