Phylogenetic relationships between the sequences in this study and the reference sequences of Cryptosporidium in GenBank and an outgroup, using a neighbor-joining (NJ) method. The genetic distance was calculated based on the Kimura 2-parameter model. Representative nucleotide sequences identified in this study are marked by black dots. The numbers on the branches represent the bootstrap percentage values for 1,000 replicates and are shown in the tree with values greater than 50%.
