What is the phylogenetic position of Cryptosporidium?

The phylogenetic position of Cryptosporidium is elusive. Although previous studies based solely upon small-subunit (SSU) rRNA sequences suggested that the genus was an early emerging lineage among the Apicomplexa, bootstrap support for this placement was low. Here, the phylogenetic position of Cryptosporidium has been re-evaluated for SSU rRNA, fused SSU/large-subunit (LSU) rRNA and six protein sequences using traditional distance-based...
