short report: echinococcus granulosus from xinjiang, pr china: cdnas encoding the eg95 vaccine antigen are expressed in different life cycle stages and are conserved in the oncosphere.the eg95-based vaccine protects sheep from infection with the dog tapeworm echinococcus granulosus. the eg95 encoding gene is a member of a multigene family, several members of which are expressed in the oncosphere, believed to be the target of immunity induced by the vaccine. e. granulosus exhibits extensive intraspecific (strain) variation, and variability of the eg95 gene in different isolates of e. granulosus may directly impact the effectiveness of the eg95-based vaccine. we analyzed the eg ...200312556145
morphological and molecular characteristics of echinococcus multilocularis and echinococcus granulosus mixed infection in a dog from xinjiang, china.the xinjiang plateau of western china has been shown to have a high prevalence for human cystic echinococcosis (ce) caused by echinococcus granulosus, and human alveolar echinococcosis (ae) caused by echinococcus multilocularis. the domestic dog is suspected to be the primary definitive host for the transmission of both e. granulosus and e. multilocularis to humans in this locality. seventeen of 30 stray dogs from hejing county of xinjiang were found positive for e. granulosus post mortem, and o ...200616616990
at least two genetically distinct large babesia species infective to sheep and goats in china.a fatal disease of sheep and goats in the northern part of china has been reported to be due to babesia ovis. however, some characteristics of the causative agent in recent reports are not in accordance with the original attributes ascribed to this parasite. therefore, the 18s small subunit ribosomal rna (18s rrna) genes of a number of babesia isolates in china were sequenced and compared with that of other babesia and theileria species in an attempt to clarify their taxonomic position. in the p ...200717531391
the development and evaluation of a loop-mediated isothermal amplification (lamp) method for detection of babesia spp. infective to sheep and goats in china.the loop-mediated isothermal amplification (lamp) reaction is a method that amplifies with high sensitivity, efficiency, and rapidity, deoxyribonucleic acid (dna) under isothermal condition in simple incubators. two primer sets for the lamp method were designed using the nucleotide sequences of 18s rrna gene of babesia sp. bq1 (lintan) and babesia sp. xinjiang-2005 isolated in china. the primers were used to detect parasite dna extracted from infected blood and purified parasites by lamp. the sp ...200818504039
a pilot study for control of hyperendemic cystic hydatid disease in china.cystic hydatid disease (chd) is a global parasitic zoonosis caused by the dog tapeworm, echinococcus granulosus. the disease is hyperendemic in western china because of poor economic development; limited community knowledge of chd; widespread, small-scale household animal production; home killing of livestock; and the feeding of dogs with uncooked offal.200919859535

radiocarbon-dated archaeological record of early first millennium b.c. mounted pastoralists in the kunlun mountains, china.pastoral nomadism, as a successful economic and social system drawing on mobile herding, long-distance trade, and cavalry warfare, affected all polities of the eurasian continent. the role that arid inner asia, particularly the areas of northwestern china, kazakhstan, and mongolia, played in the emergence of this phenomenon remains a fundamental and still challenging question in prehistoric archaeology of the eurasian steppes. the cemetery of liushiu (xinjiang, china) reveals burial features, br ...201121911387
diversity and abundance of the rumen and fecal methanogens in altay sheep native to xinjiang and the influence of diversity on methane emissions.this study aims to investigate the influence of diet roughage proportion on the methanogenic communities from the rumen and fecal samples in altay local sheep native to xinjiang and better understand the association of methanogenic diversity or abundance with methane emissions of the ruminants. in this study, the high roughage diet was found to cause more methane emissions for either maintenance or ad-lib group, but the total methanogenic abundance was not influenced by roughage proportion and s ...201122038025
[polymorphism at codons 136, 141 and 154 in the ovine prion protein gene in the state of xinjiang].scrapie is a fatal and infectious neurodegenerating disease. the polymorphism in the prion protein (prnp) gene is linked to the development of clinical signs of scrapie. the most important polymorphism appears to be at codons at 136(v/a), 154(h/r), and 171(h/q/r). in this study, we investigated the polymorphisms at these codons in 746 individuals among ten sheep breeds (i.e., aletai, bashibai, bayinbuluke, celehei, duolang, he tian, chinese merino, german merino, texel, and suffolk sheep) in xin ...201021513168
a review of research progress of fecb gene in chinese breeds of sheep.fecb gene is a major gene responsible for high prolificacy firstly identified in booroola merino sheep. subsequently, many other aspects of the fecb including endocrinology, fetal and postnatal growth were studied. a forced pcr-rflp method was performed to screen some chinese breeds or strains of sheep to determine if fecb gene is responsible for their high prolificacies. the fecb gene was present in some chinese prolific breeds of sheep, such as huyang, small tail han (sth), cele, duolang sheep ...200919201555
