The eastern Qinghai-Tibet plateau of China is a highly endemic region of echinococcosis where sensu stricto (sheep strain), , and are distributed sympatrically. We developed a polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) method for the identification of the three species in this region. The PCR-RFLP showed the dual infection of animals with different spp. The first case was a domestic dog concurrently infected with adults of and . The second case was a plateau pika () harboring metacestodes of and in the liver. The high susceptibility of some mammalian hosts to the parasites and the high prevalence of the three co-endemic species probably increase the chance of mixed infections in the eastern Tibetan plateau.
