Amplification of genomic DNA fragments of Sarcocystis muris (Apicomplexa) cyst merozoites encoding a thiol (cysteine) proteinase.
Parasites of the phylum Apicomplexa (Sporozoa) cause diseases such as malaria, toxoplasmosis, or intestinal coccidiosis. Invasive stages possess typical apical organelles such as dense granules that harbor a broad range of polypeptides that are believed to take part in the parasite-host cell interaction. In previous studies a 26-kDa polypeptide of dense granules from Sarcocystis muris cyst merozoites (bradyzoites) was characterized as a thiol (cysteine) proteinase. In this paper a method is demonstrated to amplify DNA fragments from genomic DNA of S. muris cyst merozoites by polymerase chain reaction, which probably code for the 26-kDa antigen.
