Distribution of Cryptosporidium species in Tibetan sheep and yaks in Qinghai, China

Veterinary Parasitology, 2016
Few data are available on the distribution of Cryptosporidium species in Tibetan sheep and yaks, which are free-range animals living in a cold, low oxygen, and high ultraviolet radiation habitat. In this study, 904 fecal specimens were collected from 350 Tibetan sheep and 554 yaks in six counties. Cryptosporidium spp.

Detecting signatures of selection within the Tibetan sheep mitochondrial genome

Mitochondrial DNA Part A, 2016
Tibetan sheep, a Chinese indigenous breed, are mainly distributed in plateau and mountain-valley areas at a terrestrial elevation between 2260 and 4100 m. The herd is genetically distinct from the other domestic sheep and undergoes acclimatization to adapt to the hypoxic environment.

Transcriptomic study of testicular hypoxia adaptation in Tibetan sheep

Reproduction in Domestic Animals
AbstractThe Tibetan sheep is a typical hypoxia-tolerant mammal, which lives on the plateau, an altitude of between 2,500 and 5,000 meters above sea level, the study of its hypoxic adaptation mechanism provides reference for exploring the hypoxic adaptation mechanism of other animals.

The regulatory role of BMP4 in testicular Sertoli cells of Tibetan sheep

Journal of Animal Science, 2022
Abstract This study aimed to determine the regulatory mechanism of bone morphogenetic protein 4 (BMP4) gene in the testes of Tibetan sheep and its role in the blood–testis barrier (BTB). First, we cloned BMP4 gene for bioinformatics analysis, and detected the mRNA and protein expression levels of BMP4 in the testes of Tibetan sheep pre ...

Blood mineral status of grazing Tibetan sheep in the Northeast of the Qinghai–Tibetan Plateau

Livestock Science, 2011
Abstract We investigated the macro-mineral status in free-grazing Tibetan sheep (Ovis aries) and their forage diets. The study was conducted in 4 counties in the northeast of the Qinghai–Tibetan Plateau. Forage samples and blood serum from 20 sheep in each county were collected in July (summer) and December (winter), and analyzed to determine the ...

Tibetan Wild Sheep Scandal

2012
High rolling hills flank us as we drive up a remote valley in central Qinghai, heading generally eastward as part of our 2006 Tibetan Plateau traverse, described in Chapter 7. It is December 5 and here at over 15,500 feet it is bitter cold. On a ridge crest, we spot a Tibetan argali sheep, a large ram standing proudly erect, head raised and displaying ...

Seroprevalence of Toxoplasma gondii Infection in Tibetan Sheep in Tibet, China

Journal of Parasitology, 2011
In the present investigation, the seroprevalence of Toxoplasma gondii antibodies in 455 Tibetan sheep in Tibet, China, was examined using an indirect hemagglutination test. Of these, 26 (5.7%) Tibetan sheep were seropositive at the cut-off of 1:64 serum dilution.

[Comparisons of endocrine hormones levels between Tibetan antelope and Tibetan sheep].

Sheng li xue bao : [Acta physiologica Sinica], 2013
The Tibetan antelope, a prototype mammal, has developed a unique adaptation to extreme high altitude-associated hypoxia. To investigate the role of the endocrine system in adaptation to high altitude in the Tibetan antelope, comparisons of endocrine hormones levels between Tibetan antelope (n = 9) and Tibetan sheep (n = 10) were performed.

Seroprevalence of Toxoplasma gondii Infection in Tibetan Sheep in Northwestern China

Journal of Parasitology, 2010
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.
