theileriosis of sheep and goats in china.theileriosis is an important disease of sheep and goats in west china. its main distribution includes qinghai, gansu, ningxia, inner mongolia, shaanxi and sichuan. the epidemic period is from late march to july with april-may being the peak months. this is the period of most intensive tick attack by haemaphysalis qinghaiensis (77.2-99.24%) during the year. it has been proved that the nymphs and adults, which develop from larvae and nymphs engorged on infected sheep or goats can transmit the path ...19979512737
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
molecular characterization of cryptosporidium from animal sources in qinghai province of china.the presence of cryptosporidium oocysts in 20 zoo animals of the xining zoo, 16 farm yaks and 42 farm goats in qinghai province, china was investigated by an immunofluorescence test (ift). the species and/or genotypes were determined by nested polymerase chain reaction (pcr) and sequence analysis of a fragment of the small subunit (ssu) rrna gene. cryptosporidium oocysts were found in 16 zoo animals, 2 yaks, and 15 goats by ift. the ift positive samples were further investigated by pcr, and 16 o ...200717701218
preliminary study of metal in yak (bos grunniens) milk from qilian of the qinghai plateau.63 samples of yak milk were analyzed by the method of icp-aes of metal elements for aluminum, cadmium, silver and chromium which can reveal the exposed level around yak farm. the metal elements of yak milk were compared to reference data for cow milk, sheep milk, buffalo milk and goat milk. in addition, the concentration was compared to ptwi (provisional tolerable weekly intake) established by the jecfa (who/fao) for metal intake/body weight per week of cadmium, aluminum, and chromium level was ...201121516296
seroprevalence of toxoplasma gondii infection in tibetan sheep in northwestern china.the seroprevalence of toxoplasma gondii infection in tibetan sheep was surveyed in qinghai province, northwestern china, in may and june 2010. in total, 580 serum samples was collected from 6 counties, and antibodies to t. gondii were detected by indirect hemagglutination (iha) test. antibodies to t. gondii were found in 29.8% (173/580); regional differences showed the highest prevalences in nangqian county (39.4%) and zaduo county (48.7%). the results of the present study indicate that infectio ...201021158639
[genetic effect of the marker assisted selection on economic traits of goats].the genetic relationships between economic traits and genetic markers were studied in 147 goats including chaidamu goat (cs), chaidamu cashmere goat (crs) and liaoning cashmere goat (lrs) in qinghai province, china. crs was the population of csxlrs crossbred. the results showed as follows: the selection reaction of these blood protein polymorphisic loci were great, such as esd, lap and p(a-3); and esd2-2, lapbb and pa-32-2 were the superior marker genotypes on body weight ,cashmere yield and cas ...200415640075
