| epidemiological studies on cystic echinococcosis in china--a review. | in 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 ... | 1995 | 7546341 |
| yersinia enterocolitica o9 as a possible barrier against y. pestis in natural plague foci in ningxia, china. | a survey of yersinia spp, as related to plague control, was made in haiyuan of ganning loess plateau plague focus, yanchi of inner mongolia plateau plague focus, and yinchuan city, as a control area, in ningxia, china. in haiyuan, where the main plague reservoir was mongolian ground squirrel (citellus alaschanicus) living in the prairie, y. enterocolitica o9 was frequently isolated from pigs, dogs, rodents living in and around houses, but only rarely from hare and mongolian ground squirrel. in y ... | 2001 | 11116388 |
| epidemiology of alveolar echinococcosis with particular reference to china and europe. | human alveolar echinococcosis (ae), caused by the metacestode of the fox tapeworm echinococcus multilocularis, is the most pathogenic zoonosis in temperate and arctic regions of the northern hemisphere. prospective collection of human cases in some areas and mass screenings using ultrasound imaging and confirmation with serological techniques have markedly improved our knowledge of the epidemiology of the disease in humans during the past two decades. transmission occurs when eggs of the tapewor ... | 2003 | 15027607 |
| [sequencing of mitochondrial dna cytochrome oxidase subunit i gene in sarcosaphagous flies from 14 provinces in china]. | to detect the 278 bp region of gene of the cytochrome oxidase subunit i (coi) in mitochondral dna (mtdna) of sarcosaphagous flies, identify the species of sarcosaphagous flies, and provide reference for forensic application. | 2010 | 20818074 |
| [alveolar echinococcosis in china: current data]. | very few information about alveolar echinococcosis in china is available outside the country. the aim of the authors is to give some precisions about the human cases and the infection in the natural animal hosts. it occurs in 3 distinct foci which comprise poor and remote rural areas. approximately, 420 cases of human disease have been detected, and the most intense focus is ningxia province in central china. in all areas, the adult tapeworm is frequently found in v. vulpes, v. corsac, and in th ... | 1992 | 1422277 |
| landscape composition and spatial prediction of alveolar echinococcosis in southern ningxia, china. | alveolar echinococcosis (ae) presents a serious public health challenge within china. mass screening ultrasound surveys can detect pre-symptomatic ae, but targeting areas identified from hospital records is inefficient regarding ae. prediction of undetected or emerging hotspots would increase detection rates. voles and lemmings of the subfamily arvicolinae are important intermediate hosts in sylvatic transmission systems. their populations reach high densities in productive grasslands where food ... | 2008 | 18846237 |
| community surveys and risk factor analysis of human alveolar and cystic echinococcosis in ningxia hui autonomous region, china. | to 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. | 2006 | 17128341 |
| transmission ecology of echinococcus multilocularis: what are the ranges of parasite stability among various host communities in china? | a striking feature of the transmission ecology of echinococcus multilocularis in china is the diversity of hosts that contribute to the parasite cycle. considering the population dynamics of key reservoir intermediate hosts and the ratio of their preferred habitat in a landscape (rompa) is essential to understanding transmission, but the numerous communities in which the parasite cycles and the extent of those communities is currently far from being fully documented. on the tibetan plateau grass ... | 2006 | 16361111 |
| [preliminary investigation of liver alveolar echinococcosis and liver cystic, echinococcosis in xiji county, ningxia]. | this article reports on the result of an investigation on the prevalence of liver alveolar echinococcosis (lae) and liver cystic echinococcosis (lce) in the peasants and the residents of xiji county, ningxia hui autonomous region. among 2,389 selected persons examined with b-ultrasound, 197 cases were diagnosed to have lae or lce; the prevalence being 8.2%. of the 197 cases, 141 (5.9%) had lae; 56 (2.3%) had lce. among 1,413 peasants, 9.7% had lae; 3.8% had lce. among 976 residents, 0.4% had lae ... | 1991 | 1873889 |
