Phylogenetic relationships of Cryptosporidium spp. isolates in this study to other known Cryptosporidium spp. inferred by neighbor-joining analysis of the SSU rRNA gene. Sequences were retrieved from GenBank, aligned using ClustalW, and analyzed using MEGA 11 software. The neighbor-joining method was used to construct the trees from the Kimura-2-parameter model. Branch numbers represent percent bootstrapping values from 1000 replicates, with values of more than 50% shown in the tree. Cryptosporidium spp. found in this study are marked with a ●.
