Prevalence of gastrointestinal parasites in free-range yaks (Bos grunniens) in Gansu Province, Northwest China.

Background: Little information about the prevalence of gastrointestinal parasites in yaks (Bos grunniens) in northwest China is available. Therefore, the objective of the study was to quantify faecal egg counts of gastrointestinal parasites (helminths and coccidia) in free-range yaks from Gannan Tibetan Autonomous Prefecture, Gansu Province, Northwest China.

Results: Parasites were detected in 290 of 733 (39.

Seroprevalence and Risk Factors of Fascioliasis in Yaks, , from Three Counties of Gansu Province, China.

The aim of this study was to determine the seroprevalence and risk factors of fascioliasis in yaks, , from 3 counties of Gansu Province in China. A total of 1,584 serum samples, including 974 samples from white yaks from Tianzhu, 464 from black yaks from Maqu, and 146 from black yaks from Luqu County, were collected and analyzed using ELISA to detect IgG antibodies against . The overall seroprevalence was 28.

First Report of Bovine Leukemia Virus Infection in Yaks (Bos mutus) in China.

Enzootic bovine leukosis (EBL) is a chronic lymphosarcoma disease of cattle caused by bovine leukemia virus (BLV). No information is available concerning the epidemiology of BLV infection in yaks (Bos mutus). One thousand five hundred and eighty-four serum samples from 610 black yaks and 974 white yaks from Gansu province, northwest China, were collected between April 2013 and March 2014 and tested for BLV antibodies using a commercially available ELISA kit.

Seroprevalence and correlates of Toxoplasma gondii infection in dairy cattle in northwest China.

Prevalence of antibodies to Toxoplasma gondii and risk factors with infection were assessed in dairy cattle from Gansu Province and Ningxia Hui Autonomous Region (NXHAR), northwest China. In total, 1657 serum samples were collected and assayed by the modified agglutination test. The overall seroprevalence was 4.

The prevalence of antibodies to Toxoplasma gondii in horses in Changji Hui Autonomous Prefecture, Xinjiang, northwestern China.

Toxoplasmosis is a worldwide zoonosis caused by Toxoplasma gondii, which can infect warm-blooded animals and humans. The present study was performed to investigate the seroprevalence of T. gondii in horses in Xinjiang, northwestern China.

First Report of Coxiella burnetii Seroprevalence in Tibetan Sheep in China.

Query (Q) fever is a vector-borne zoonosis caused by the obligate intracellular pathogen Coxiella burnetii. Animals, including dogs, cats, cattle, and sheep, can be infected by C. burnetii.

Seroprevalence and risk factors of Toxoplasma gondii in Tibetan Sheep in Gansu province, Northwestern China.

Background: Toxoplasma gondii, a protozoan parasite, infects almost all warm-blooded animals and humans. Limited information is available about T. gondii infection in Tibetan Sheep in Gansu province, northwestern China.

First report of Babesia bigemina infection in white yaks in China.

White yaks, a unique yak breed and the pearl of the plateau, only live in Tianzhu Tibetan Autonomous County (TTAC), Gansu Province, northwest China, contributing significantly to local economy. However, there was no information on the prevalence of Babesia bigemina in white yaks. In this study, a total of 974 serum samples collected from white yaks in TTAC were examined for specific antibodies against B.

Seroprevalence and risk factors of Chlamydia abortus infection in free-ranging white yaks in China.

Background: Chlamydia is gram-negative obligate bacteria which causes a wide variety of diseases in humans and animals. To date, there are a few reports about the seroprevalence of Chlamydia and the risk factors associated with Chlamydia infection in yaks in the world. In this study, 974 blood samples were collected from white yaks (Bos grunniens) in Tianzhu Tibetan Autonomous County, Gansu province, northwest China from June 2013 to April 2014.

Seroprevalence and risk factors of Chlamydia abortus infection in Tibetan sheep in Gansu province, northwest China.

Chlamydia abortus, an important pathogen in a variety of animals, is associated with abortion in sheep. In the present study, 1732 blood samples, collected from Tibetan sheep between June 2013 and April 2014, were examined by the indirect hemagglutination (IHA) test, aiming to evaluate the seroprevalence and risk factors of C. abortus infection in Tibetan sheep.

Seroprevalence and risk factors of Toxoplasma gondii infection in domestic sika deer (Cervus nippon) in northeastern China.

Toxoplasmosis is a worldwide zoonosis caused by Toxoplasma gondii, which can infect warm-blooded animals and humans. A serological survey was undertaken to examine the seroprevalence and risk factors associated with T. gondii infection in sika deer in northeastern China.

First report of Cryptosporidium spp. in white yaks in China.

Background: Cryptosporidium is an enteric apicomplexan parasite, which can infect yaks, leading to reduction of milk production and poor weight gain. White yak (Bos grunniens) is a unique yak breed inhabiting only in Tianzhu Tibetan Autonomous County, Gansu province, northwestern China. The objective of the present study was to molecularly determine Cryptosporidium infection and species in white yaks.
