Selected information on nucleotide sequences for ribosomal genes (SSU rRNA and ITS2), Cryptosporidium oocyst wall protein (COWP), LIB13, and DnaJ-like proteins (or heat shock protein 40 [HSP40]) currently available in GenBank is also shown. LIB13 is a Cryptosporidium-specific gene with unknown function. Abbreviations: SSU, small subunit; ITS, internal transcribed spacer; NA, not available.
