The number of oocysts per gram of faeces from each vole ranged from 1. 5×106 to 1. 8×108. A partial sequence of small subunit 18S rDNA (SSU rDNA) obtained in this study was registered as Cryptosporidium sp. Mrb001 (GenBank accession no. AB477098) and had the highest similarity to Cryptosporidium sp. 05. 1513.Rb (GenBank accession no. HM015880.1), which originated from drinking water in the United Kingdom (98. 5%). Phylogenetic tree analysis indicated that Cryptosporidium sp. Mrb001 clustered with several waterborne Cryptosporidium isolates and other Cryptosporidium spp. that originated from voles that inhabit wetlands in Hokkaido. We provided information about this cryptosporidial parasite isolated from Myodes vole.}, pages = {45--48}, title = {北海道土着のエゾヤチネズミから分離されたクリプトスポリジウム種,Mrb001株}, volume = {46}, year = {2022} }
