Abstract

The genes encoding 18S rRNA and internal transcribed spacer 1 (1TS1) of Cryptosporidium parvum and Cryptosporidium muris were amplified from oocysts by PCR utilizing primers complementary to conserved regions of the 5' end of 18S and 5.8S rRNA. PCR products were cloned and the complete nucleotide sequences of two clones of each Cryptosporidium species were determined. The 18S rRNA genes of C. parvum and C. muris showed more than 99% sequence identity.
