Abstract

The species identification of an echinococcal lesion in the liver of a yak in the Qinghai-Tibet plateau region of China, where both and are present, was difficult to determine because of the atypical appearance of the lesion. Polymerase chain reaction–based mitochondrial genotyping allowed us to discriminate the species. Nucleotide sequences of the cytochrome oxidase subunit 1 () and cytochrome () genes amplified from the echinococcal lesion demonstrated that the yak was infected with the G1 genotype (sheep strain).
