Compared with dairy and beef cattle, few data are available on the occurrence and distribution of Cryptosporidium species in yaks, which live in a very different habitat. In this study, 327 fecal specimens were collected from yaks in 4 counties in Qinghai Province of China and screened for Cryptosporidium by nested PCR analysis of the 18S rRNA gene. A total(More)
Enterocytozoon bieneusi, the most frequently diagnosed microsporidian species in humans, is also identified in a wide range of animals. To date, few data are available on E. bieneusi in yaks (Bos grunniens). In this study, we examined the occurrence and genotype identity of E. bieneusi in yaks in four counties in Qinghai Province of China. Of 327 fecal(More)
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. were detected and differentiated by PCR(More)
Triphenyltin (TPT), an endocrine disruptor, is polluting the global environment through its worldwide use. However, information concerning the mechanisms of TPT biodegradation and cellular metabolism is severely limited. Therefore, these processes were elucidated through experiments involving TPT biosorption and degradation, intracellular metabolite(More)
Cryptosporidiosis, giardiasis, and microsporidiosis are important waterborne diseases. In the standard for wastewater treatment plant (WWTP) effluents in China and other countries, the fecal coliform count is the only microbial indicator, raising concerns about the potential for pathogen transmission through WWTP effluent reuse. In this study, we collected(More)
Cyanobacterial blooms in freshwaters have become one of the most widespread of environmental problems and threaten water resources worldwide. Previous studies on cyanobacteria in Lake Taihu often collected samples from one site (like Meiliang Bay or Zhushan Bay) and focused on the variation in patterns or abundance of Microcystis during the blooming season.(More)
