Cryptosporidium varanii takes precedence over C. saurophilum

We present biological as well as genetic analysis of Cryptosporidium varanii at the 18S rRNA and actin loci and show that it is genetically identical to C. saurophilum. As C. varanii was described prior to C. saurophilum, it takes precedence over C. saurophilum and therefore C. saurophilum should be considered a junior synonym of C. varanii.
