| echinococcus shiquicus n. sp., a taeniid cestode from tibetan fox and plateau pika in china. | the taeniid cestode echinococcus shiquicus n. sp. was found from the tibetan fox vulpes ferrilata and the plateau pika ochotona curzoniae in the qinghai-tibet plateau region of china. in the adult stage, e. shiquicus from the foxes is morphologically similar to echinococcus multilocularis. however, the new species is differentiated by its smaller rostellar hooks, fewer segments, distinct position of genital pore in the mature segment and fewer eggs in the gravid segment. hydatid cysts of e. shiq ... | 2005 | 15862582 |
| echinococcus shiquicus, a new species from the qinghai-tibet plateau region of china: discovery and epidemiological implications. | in shiqu county of the qinghai-tibet plateau, many wild and domestic mammals are involved in the transmission cycles of echinococcus spp. echinococcus multilocularis and echinococcus granulosus genotype g1 (sheep strain) are sympatrically distributed in the plateau. in 1995, we identified a unique strobilate stage of echinococcus from the tibetan fox, vulpes ferrilata, but considered it to be a variant of e. multilocularis. subsequent molecular genetic studies revealed that a hydatid cyst from t ... | 2006 | 16337180 |
| dual infection of animal hosts with different echinococcus species in the eastern qinghai-tibet plateau region of china. | the eastern qinghai-tibet plateau of china is a highly endemic region of echinococcosis where echinococcus granulosus sensu stricto (sheep strain), echinococcus multilocularis, and echinococcus shiquicus are distributed sympatrically. we developed a polymerase chain reaction-based restriction fragment length polymorphism (pcr-rflp) method for the identification of the three species in this region. the pcr-rflp showed the dual infection of animals with different echinococcus spp. the first case w ... | 2006 | 16896135 |
| surveillance of echinococcus isolates from qinghai, china. | echinococcosis is highly endemic over large parts of the qinghai-tibet plateau (qtp), china. based on a large number of samples, we present data on the current presence, host distribution, and genetic diversity of echinococcus in the qinghai province, located in the northeastern corner of the qtp and constituting >25% of the area of the plateau. we used 521 samples (including 451 newly collected samples and 70 samples from our previous study) from humans, yaks, sheep, goats, dogs, fox, plateau p ... | 2015 | 25480467 |
| development of three pcr assays for the differentiation between echinococcus shiquicus, e. granulosus (g1 genotype), and e. multilocularis dna in the co-endemic region of qinghai-tibet plateau, china. | to investigate echinococcosis in co-endemic regions, three polymerase chain reaction (pcr) assays based on the amplification of a fragment within the nadh dehydrogenase subunit 1 (nd1) mitochondrial gene were optimized for the detection of echinococcus shiquicus, echinococcus granulosus g1, and echinococcus multilocularis dna derived from parasite tissue or canid fecal samples. specificity using parasite tissue-derived dna was found to be 100% except for e. shiquicus primers that faintly detecte ... | 2013 | 23438764 |
| first report of echinococcus shiquicus in dogs from eastern qinghai-tibet plateau region, china. | echinococcus shiquicus was discovered in foxes and pika wildlife hosts in sichuan province, china in 2005. faecal samples from dogs collected in a previous echinococcosis purgation survey from shiqu county, ganzi tibetan autonomous prefecture (sichuan) were screened by copropcr to investigate the possible occurrence of e. shiquicus. in addition, coprodna extracted from 8 necropsied tibetan foxes (vulpes ferrilata), the natural host of e. shiquicus, were also included. thirty (6/20) percent of fa ... | 2013 | 23507509 |
| [biological features of a new echinococcus species (echinococcus shiquicus) in the east of qinghai-tibet plateau]. | in the eastern qinghai-tibet plateau region, a variety of domestic and wild mammals are involved in the transmission cycles of echinococcus species. e. granulosus and e. multilocularis are known being sympatrically distributed in the plateau region. recently, an unknown echinococcus species was isolated from infected plateau pika (ochotona curzoniae) and tibetan fox (vulpes ferrilata). the species shows quite distinct characteristics on morphology, genetics, host specificity and geographical dis ... | 2008 | 24818378 |
