| an epidemiological survey of cystic echinococcosis among tibetan school pupils in west china. | human cystic echinococcosis (ce) caused by infection with a larval stage of echinococcus granulosus is a serious public health problem in west china. because ce is a zoonosis, dogs and livestock are important hosts in transmission. tibetans, especially teenagers, have a natural relationship with these definitive and intermediate hosts in west china and although some areas of tibet are therefore ce-endemic, few, if any, detailed community studies have been reported. a total of 451 tibetan school ... | 2001 | 11579862 |
| survey on cystic echinococcosis in tibetans, west china. | human cystic echinococcosis (ce) is a serious public health problem in west china. the tibetan has a nature relation with these definitive and intermediate hosts in west china. although tibet is ce endemic, a few community studies have been reported. eight hundred and eighty two tibetans residing in the three rural communes of tianzhu county, gansu province of west china were investigated by serology and ultrasound scanning. 11.2% serum antibody positive rate in elisa test was found out, and a 1 ... | 2002 | 12039679 |

| 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 |
| 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 |
| 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 |

| canis lupus familiaris involved in the transmission of pathogenic yersinia spp. in china. | to investigate canines carrying pathogens associated with human illness, we studied their roles in transmitting and maintaining pathogenic yersinia spp. we examined different ecological landscapes in china for the distribution of pathogenic yersinia spp. in canis lupus familiaris, the domestic dog. the highest number of pathogenic yersinia enterocolitica was shown from the tonsils (6.30%), followed by rectal swabs (3.63%) and feces (1.23%). strains isolated from plague free areas for c. lupus fa ... | 2014 | 24861841 |
| phylogenetic analysis of tibetan mastiffs based on mitochondrial hypervariable region i. | recently, the number of tibetan mastiffs, which is a precious germplasm resource and cultural heritage, is decreasing sharply. therefore, the genetic diversity of tibetan mastiffs needs to be studied to clarify its phylogenetics relationships and lay the foundation for resource protection, rational development and utilization of tibetan mastiffs. we sequenced hypervariable region i of mitochondrial dna (mtdna) of 110 individuals from tibet region and gansu province. a total of 12 polymorphic sit ... | 2017 | 28360396 |
| spatial modelling and ecology of echinococcus multilocularis transmission in china. | recent research in central china has suggested that the most likely transmission mechanism for echinococcus multilocularis to humans is via domestic dogs which are allowed to roam freely and hunt (infected) small mammals within areas close to villages or in areas of tented pasture. this assertion has led to the hypothesis that there is a landscape control on transmission risk since the proximity of suitable habitat for susceptible small mammals appears to be the key. we have tested this hypothes ... | 2006 | 16371253 |
| an epidemiological and ecological study of human alveolar echinococcosis transmission in south gansu, china. | human alveolar echinococcosis (ae) is usually a rare, highly pathogenic zoonotic disease, transmitted across the northern hemisphere between fox and rodent hosts. in china the first cases were described in 1965; however very few epidemiological studies have been undertaken since. following identification in 1991 of a serious focus of human ae in south gansu province, detailed village-based community and ecological studies were carried out between 1994 and 1997. hepatic ultrasound mass screening ... | 2000 | 11080507 |
| a large focus of alveolar echinococcosis in central china. | human alveolar echinococcosis (ae) is a rare and highly pathogenic helminthic zoonosis due to infection with the intermediate stage of the small fox tapeworm, echinococcus multilocularis. parasite transmission is restricted to northern latitudes, including central and north china, from where few clinical and no detailed community studies have been reported. in august, 1991, 65 (5%) of 1312 people residing in three rural communes of zhang county, gansu province, china were diagnosed as having hep ... | 1992 | 1357252 |
| development of a lamp assay for detection of leishmania infantum infection in dogs using conjunctival swab samples. | leishmania infantum infections in dogs play a crucial role in the transmission of pathogens causing visceral leishmaniasis to humans in the gansu province, northwest china. to be able to control zoonotic transmission of the parasite to humans, a non-invasive loop-mediated isothermal amplification (lamp) assay to specifically detect l. infantum infections in dogs was developed. | 2015 | 26169060 |
