assessment of echinococcus granulosus polymorphism in qinghai province, people's republic of china.cystic echinococcosis (ce) is highly endemic in the chinese province of qinghai, located on the tibetan plateau. the echinococcus granulosus sheep strain has already been reported in this focus. to improve our understanding of the role the parasite plays in the high prevalence observed in humans, we assessed the genetic polymorphism of 55 e. granulosus samples (37 from humans) using three discriminative mitochondrial markers: coxi, nadi and atp6. we obtained a total of 13 distinct genotypes whic ...200818309521
hydatidosis in a chapman's zebra (equus burchelli antiquorum).a 14-year-old male chapman's zebra had been treated for a cervical granulomatous cellulitis for 3 months prior to sudden death associated with myocardial fibrosis. incidental findings at necropsy included multiple 3-8-cm unilocular cysts in the liver and lungs. cysts contained either a clear fluid with or without hydatid sand or a gelatinous substance with foci of mineralization. light and scanning electron microscopic examination of the hydatid sand revealed free protoscolices as well as intact ...200111724148
