The obligate 2-host parasitic cycle of Echinococcus granulosus is predominantly synanthropic. Dogs are the usual definitive hosts, and lots of mammalian species can be intermediate hosts, including domestic livestock and human[I2]. In the Tibetan plateau, China, the population is mainly Tibetans primarily engaged in livestock husbandry and CE is therefore a health problem for both people and animal in Tibetan communities. The reported infection rate of Echinococcus gronulosus in slaughtered yak in slaughterhouses is usually very high, being about 50% or higher as reported, and the liver and lungs are the main affected organs[34].展开更多

This hypertrophy, characterized by an increase in protein conten and cell size, as well as an accumulation of extracellular matrix, is a key process which may lead subsequently to tubulointerstitial fibrosis and end-stage renal failure.展开更多

The authors alleged that this 'allele reversal' might simply result from maternal age and suggested that we test this on our datasets. Unfortunately,展开更多
