Phylogenetic relationships among isolates of Cryptosporidium: evidence for several new species.

Abstract

Isolates of Cryptosporidium were characterized using nucleotide sequence analysis of the 18S rRNA and dihydrofolate reductase genes and also random-amplified polymorphic DNA analysis. Phylogenetic analysis confirmed the validity of the species of Cryptosporidium examined in this study such as Cryptospordium muris and Cryptosporidium baileyi, and also reinforced evidence from numerous researchers worldwide suggesting that Cryptosporidium parvum is not a single uniform species. The data obtained provided strong support for the validity of Cryptosporidium felis. Evidence suggests that the newly identified marsupial and pig genotypes may also be distinct and valid species, but biological studies are required for confirmation.
