Phylogenetic tree of parvum cysts inferred via neighbor‒joining analysis of the COWP gene sequence. Cryptosporidium muris (house rat) and Cryptosporidium andersoni (cattle) from China were used as the out-group. Nonparametric bootstrap values (based on 1000 replicates) are shown at each node. The scale bar indicates the number of substitutions per site
