Diarrhea is one of the main causes of animal deaths especially in neonatal calves. The objective of this study was to investigate the blood serum for cobalt (Co), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), Molybdenum (Mo), selenium (Se), and zinc (Zn) concentrations in yak serum samples by inductively coupled plasma mass spectrometry (ICP-MS)(More)
Lungworms, a world wild distributed parasites cause serious respiratory diseases to the pigs. A high infection rate of Metastrongylus lungworms has been found in Tibetan pigs being slaughtered in different slaughter houses of Tibet autonomous region. The main aim of our study was to detect and confirm the lungworm parasite by the genetic characterization of(More)
Toxocara vitulorum has been rarely reported in yaks at high altitudes and remote areas of Sichuan Province of Tibetan Plateau of China. The current study was designed to investigate the prevalence, associated risk factors, and phylogenetic characteristics of T. vitulorum in yak calves on the Qinghai Tibetan plateau. Fecal samples were collected from 891 yak(More)
Toxoplasma gondii (T. gondii) is one of the most common and widespread protozoan parasite which caused toxoplasma infection in animals and humans. Toxoplasma infection in healthy people is usually asymptomatic and it can lead to serious pathological effects in congenital cases and immunodeficient patients. The aim of the study is to investigate the(More)
Toxoplasma gondii is a zoonotic protozoan parasite that infects a wide range of warm-blooded animals throughout the world. In the present study, antibodies to T. gondii were determined using a commercial indirect hemagglutination (IHA) test in wild animals in a zoo. Three of 11 giraffes (Giraffa camelopardalis) (27%), 1 of 5 wolves (Canis lupus laniger)(More)
Tibetan chickens (TBCs) live at high altitude hypoxic environment. None of the Tibial dyschondroplasia (TD) cases had been reported in TBCs, which is commonly seen in commercial broilers characterized by lameness. The underlying mechanism remains unclear. Hypoxia inducible factors (HIFs) are important regulators of cellular adaptation to hypoxic conditions.(More)
We investigated Japanese encephalitis virus (JEV) prevalence in high-altitude regions of Tibet, China, by using standard assays to test mosquitoes, pigs, and humans. Results confirmed that JEV has spread to these areas. Disease prevention and control strategies should be used along with surveillance to limit spread of JEV in high-altitude regions of Tibet.
Ascaris suum (A. suum) is the most commonly occurring worldwide internal parasite of pigs; however, little is known about this organism in Tibetan pigs in China. A study was carried to isolate and identify the characteristics of internal transcribed spacer region (ITS) gene of A. suum derived from Tibetan pigs. Adult nematodes were collected from Tibetan(More)
Toxoplasma gondii causes serious infection worldwide in humans and animals. In this study, the seroepidemiology of toxoplasmosis was investigated in wild boars (Sus scrofa) (n=377), wild rabbits (cape hare, Lapus capensis) (n=331), and wild chickens (red junglefwol, Gallus gallus) (n=571) in 4 forested and country sided area of Hubei province of China. For(More)
Parasitic nematodes of Oesophagostomum spp., commonly known as 'nodular worms' are one of the most widely distributed and prevalent emerging zoonotic nematodes. However, little is known about the prevalence and gene characteristics of those parasites in Tibetan pigs. Therefore, a study was carried out to investigate the prevalence, isolation and(More)
