Original Paper


The intraspecific variation of four laboratory-reared isolates ofTaenia taeniaformis the SRN and KRN isolates from Norwa rats,Rattus norvegicus, captured in Japan and malaysia, respectively; the BMM isolate from a house mouse,Mus musculus, captured in Belgium; and the ACR isolate from a gray red-backed vole,Clethrionomys rufocanus bedfordiae, captured in Japan was examined by various criteria. Eggs of each of the four isolates were orally inoculated into several species of intermediate host. They were most infective to the rodent species from which the original metacestode of each isolate had been isolated in the field, and only the ACR isolate was infective to the gray red-backed vole. Although little difference was found between the SRN, KRN, and BMM isolates by the other criteria, including the morphology of rostellar hooks, the protein composition of the metacestode, and restriction endonuclease analysis of DNA, the ACR isolate was clearly different from the others. It was considered that the ACR isolate was independent as a strain distinct from the other three isolates.
