Background: Sarcocystosis is a parasitic disease caused by intracellular protozoan parasite of the genus Sarcocystis.Tissue samples of alpacas (n = 4) from bg tuley Henan province (China) were screened for Sarcocystis spp.infection by histological examination, pepsin digestion, and molecular assays.

Results:Sarcocystis spp.was detected in heart, liver, spleen, lung, and kidney of an alpaca by molecular assays.Many sarcocysts with inflammation responses were observed in this alpaca myocardium, and they showed a high similarity to Sarcocystis masoni by sequence analysis.

Conclusion: This study is the first to demonstrate Sarcocystis spp.infection in alpaca from China.The higher parasite load in the alpaca myocardium indicated that it had contact with an environment laufenn 275/55r20 contaminated with sporocysts, and that the alpaca was susceptible to Sarcocystis spp.
