Toxoplasma gondii is an amphixenosis which has extensive hosts. In recent years, the prevalence of T. gondii in China has been reported, while little is known on the survey of T. gondii infection in northwest China, especially in yaks (Bos grunniens) and Tibetan mastiffs (Canis lupus familiaris). The current study survey the infection of T. gondii in(More)
The new N-containing maltooligosaccharides GIB-638 were isolated and purified from the culture filtrate of Streptomyces fradiae PWH638 using the chemoenzymatic method. Its physicochemical properties, liquid chromatographic behaviour and spectroscopic data were similar to the reported compounds acarviostatin I03 with a molecular weight of 969 Da. Its(More)
Pinus densiflora var. zhangwuensis grows fast, and its drought and salinity resistance are better than Pinus sylvestris var. mongolica. We compared cold hardiness and mechanisms of cold hardiness between the two species, to provide a theoretical basis for promoting and applying P. densiflora var. zhangwuensis in cold regions. A cold stress experiment was(More)
BACKGROUND Toxoplasma gondii is a zoonotic pathogen that can infect a range of animals and humans. Ingestion of T. gondii oocysts in soil is a significant transmission route for humans and animals acquiring toxoplasmosis. In the present study, we developed a new semi-nested PCR method to determine T. gondii oocysts distribution in soils in northwestern(More)
