摘要: DNA sequencing of 1.3 kb rDNA containing both internal transcribed spacers (ITS 1, ITS2) and adjoining rRNA coding regions in each 11 Echinococcus multilocularis isolates from Germany, Japan, Alaska resulted identical nucleotide sequences except for a single polymorphic locus 54 bp upstream the 3' end 18S region, separating Eurasian an Alaskan isolate. The same base substitution was found 2 additional Alaska. distribution resulting genotypes with regard to their origin is highly significant (>99.9%) corresponds traditional subspecies sibiricensis.
