This article reports the results of the study on the infection of Echinococcus multilocularis in humans and animals in the Qinghai Plateau from 1995 to 1998. A total of 111 cases of foam hydatid disease were treated; 73 males and 38 females; of which 10 cases of alveolar hydatidosis, alveolar echinococcosis in 2 cases, 7 cases of cysticercosis, 2 cases. Age 17 ~ 74 years old, adults are the most common. Herdsmen and peasants are the most common, other occupations are rare. There were 370 2 people in the census, 23 (0.62%) were diagnosed as B-type hypersensitive cysts and 30 (0 .81%) were positive for EM1 8 seropositivity. Both of them met the criteria of 13 0 .35%). Seven species of intermediate hosts were investigated. Infectious rates were 4.09% (18/384) and 5.36% (31/58) respectively in the yak liver of domesticated animals and in the liver of sheep and Tibetan sheep. The infection rate of wild animals The infection rates of metacercariae were 3.45% (11/319) and 12.5% (1/8) respectively in the lungs of the labial and rabbit liver and gray tail rabbit. Five species of the final host were investigated. Echinococcus multilocularis infection was confirmed in the Tibetan dogs and the domestic fowls, with infection rates of 5.08% (3/5 9) and 33.33% (4/12), respectively. Prompted the Qinghai Plateau Echinococcus multilocularis Tibetan dogs, Tibetan fox / black lip rabbit, gray tail rabbit and Tibetan dogs, Tibetan fox / yak, Tibetan sheep two types of Echinococcus multilocular life cycle chain
