is the underlying cause of a significant number of outbreaks of gastrointestinal illness in humans and animals worldwide. The purpose of this study was to elucidate the prevalence and genetic diversity of in captive alpine musk deer () in China. A total of 202 fecal samples were collected from three farms in Gansu Province, China. Identification of was conducted by nested PCR targeting the genes coding for SSU rRNA, β-giardin (), glutamate dehydrogenase () and triosephosphate isomerase (). The overall prevalence of in captive alpine musk deer in surveyed area was 19.3% (39/202). Two genetic assemblages were identified, namely assemblage A and E. Mixed genotype infections (A+E) were found in 15.4% (6/39) of positive samples. Multilocus genotyping (MLG) analysis of isolates revealed six novel assemblage A MLGs formed by two newly-described MLG-subtypes which belonged to sub-assemblage AI. To the best of our knowledge, this is the first report on MLG of isolates in captive alpine musk deer in China. The presence of zoonotic assemblages and sub-assemblages of in deer species suggests that these animals may potentially act as a reservoir of this protozoan for humans.

Spatiotemporal interactions between predators and prey are central to maintaining sustainable functioning ecosystems and community stability. For wild ungulates and their predators, livestock grazing is an important anthropogenic disturbance causing population declines and modifying their interactions over time and space. However, it is poorly understood how fine-scale grazing affects the spatiotemporal responses of predators, prey, and their interactions.

Wild ungulates play crucial roles in maintaining the structure and function of local ecosystems. The alpine musk deer (), white-lipped deer (), and red serow () are widely distributed throughout the Nyenchen Tanglha Mountains of Tibet. However, research on the mechanisms underlying their coexistence in the same habitat remains lacking.

Article Synopsis
- The ADAPT+ study was conducted to evaluate the long-term safety and effectiveness of the drug efgartigimod in adults with generalized myasthenia gravis (gMG) over a period of up to 3 years.
- The study involved 151 participants from the earlier phase 3 ADAPT study, with a significant portion (76.6%) being AChR-Ab positive, and it measured adverse events as well as improvements in disease severity using specific scoring systems (MG-ADL and QMG).
- Results showed that 84.8% of participants experienced at least one side effect, with headache and COVID-19 being the most common, while many participants achieved clinically meaningful improvements in their symptoms shortly after

In China, the population of wild musk deer, belonging to the family Moschidae, has drastically decreased in recent years owing to human activities and environmental changes. During the 1990s, artificial breeding of Alpine musk deer was conducted in Xinglong Mountain, Gansu Province, China, and their ex situ conservation was explored for over a decade. Ex situ protection is beneficial for expanding the population of animals and maintaining their genetic diversity; however, it can also induce metabolic diseases and parasitic infections and reduce reproductive capacity.
