Microsporidian spores were isolated from two squirrel monkeys (Saimiri sciureus) that had been bred at an animal-breeding colony in Japan. The spores were identified as Encephalitozoon cuniculi on the basis of nucleotide sequence analysis of the small-subunit (SSU) rRNA gene. The internal transcribed spacer (ITS) gene sequence revealed that these isolates were classified into genotype III because it contained tetrarepeats of 5'-GTTT-3'. However, the sequences of the polar tube protein (PTP) gene of the monkey isolates were not identical to a reported sequence of genotype III but were quite similar to a reported sequence of genotype II. On the other hand, sequence analysis of the spore wall protein 1 (SWP-1) gene revealed that the monkey isolates did not belong to any of genotypes I, II and III. These results suggest that the present E. cuniculi isolates of squirrel monkey origin are a new subtype of E. cuniculi ITS genotype III that can cause a disseminated infection.
