epidemiological studies on cystic echinococcosis in china--a the four decades from 1951 to 1990, the six provinces or autonomous regions (xinjiang, gansu, qinghai, ningxia, xizang and nei monggol) reported a total of 26,065 surgical cases of hydatid disease, most of which were reported in the recent decade. about one third of the patients was children and adolescents under 15 years old. so far, cystic hydatid infections of local origin have been confirmed in 22 provinces, autonomous regions and municipalities in the whole nation. findings of x-ray exam ...19957546341
molecular study of echinococcus in west-central china.west-central china is an important endemic focus of both alveolar and cystic echinococcosis where several species of intermediate host are commonly infected with echinococcus granulosus and e. multilocularis . isolates of e. granulosus were collected from humans and other animals from different geographical areas of qinghai, ningxia, gansu and sichuan, and genotyped using the mitochondrial dna marker atp synthase subunit 6 gene (atp6). the sheep strain (g1 genotype) of e. granulosus was shown to ...200516174420
simultaneous alveolar and cystic echinococcosis of the liver.alveolar echinococcosis (ae) and cystic echinococcosis (ce), caused by infection with the larval stages of echinococcus multilocularis and e. granulosus, respectively, are of major clinical importance. reports of infection with ae or ce are very common, but instances of simultaneous or dual infection are rare. we report on four cases with mixed ae/ce infections in the liver, diagnosed using retrospective surgical records and active community surveys in southern ningxia hui autonomous region (nha ...200616336985
community surveys and risk factor analysis of human alveolar and cystic echinococcosis in ningxia hui autonomous region, determine the true community prevalence of human cystic (ce) and alveolar (ae) echinococcosis (hydatid disease) in a highly endemic region in ningxia hui, china, by detecting asymptomatic cases.200617128341
serological prevalence of echinococcosis and risk factors for infection among children in rural communities of southern ningxia, assess the usefulness of serology as an indicator of echinococcus transmission for developing preventive measures against echinococcosis in rural communities.200818554249
hospital and community surveys reveal the severe public health problem and socio-economic impact of human echinococcosis in ningxia hui autonomous region, china.a comprehensive study of human echinococcosis (caused by echinococcus granulosus or e. multilocularis), including assessment of hospital records, community surveys and patient follow-up, was conducted in ningxia hui autonomous region (nhar), china. in contrast to hospital records that showed 96% of echinococcosis cases were caused by cystic echinococcosis (ce), 56% of cases detected in active community surveys were caused by alveolar echinococcosis (ae). the ae and ce cases co-existed frequently ...200616772010
unique family clustering of human echinococcosis cases in a chinese community.we have identified a significant focus and unusual clustering of human cases of cystic echinococcosis (ce) and alveolar echinococcosis (ae) in the village of nanwan, xiji county, ningxia hui autonomous region, in one of the most highly endemic areas for both diseases in china. the village, a chinese hui islamic community, is composed of 167 members of four extended families. a total of 28 people died (12 of echinococcosis) since the village was first settled in the 1950s. despite similar life pa ...200616525111
impact of anthropogenic and natural environmental changes on echinococcus transmission in ningxia hui autonomous region, the people's republic of china.echinococcus transmission is known to be affected by various environmental factors, which may be modified by human influence or natural events including global warming. considerable population growth in the last fifty years in ningxia hui autonomous region (nhar), the people's republic of china (prc), has led to dramatic increases in deforestation and modified agricultural practices. in turn, this has resulted in many changes in the habitats for the definitive and intermediate hosts of both echi ...201222827890
impact of "grain to green" programme on echinococcosis infection in ningxia hui autonomous region of china.cystic echinococcosis (ce) is endemic among the human population of xiji county, ningxia hui autonomous region, china, where the prevalence is estimated to be between 2.2% and 3.6%. government-run sheep abattoirs in xiji county have closed in recent years and, as a consequence, slaughter is carried out mostly at rural market places. the market place in xinglong township, xiji county, is home to an increasing number of stray dogs and the lack of government control over slaughter practices potenti ...201425283092
echinococcosis in ningxia hui autonomous region, northwest china.cystic echinococcosis (ce), caused by echinococcus granulosus, and alveolar echinococcosis (ae), due to e. multilocularis, are endemic to large areas of north and northwest china. here we review features of a severe focus of ae and ce in ningxia hui autonomous region (nhar), northwest china. we describe for nhar the results of surveys of hospital surgical and clinical records, including treatment of ae and ce, and active community detection of asymptomatic/early-stage cases and patient follow-up ...200818314150
