Fig. 2From: First report of Cryptosporidium viatorum and Cryptosporidium occultus in humans in China, and of the unique novel C. viatorum subtype XVaA3hPhylogenetic relationships between different subtypes of C. viatorum. Phylogenetic tree based on gp60 gene sequences of C. viatorum constructed by the neighbor-joining distance method with 1000 bootstrap replicates using MEGA 6.0 software. Individual GenBank accession numbers precede species and subtype names, which are followed by host names or water. The square indicates the C. viatorum subtype identified from a stool DNA sample in this studyBack to article page
