First detection and diversity of astroviruses in wild migratory birds of Sakhalin Island, North Pacific.

Researchers have identified Avastrovirus as a significant genus of bird viruses, linked to various avian diseases such as enteritis, growth retardation, nephritis and hepatitis. These infections can cause substantial economic losses in agrocultureand have a widespread impact on global food production. Although there have been numerous studies on these viruses, most of them-mainly focuses on poultry.

[Metabolic Profile of Gut Microbiota and Levels of Trefoil Factors in Adults with Different Metabolic Phenotypes of Obesity].

Obesity is associated with changes in the gut microbiota, as well as with increased permeability of the intestinal wall. In 130 non-obese volunteers, 57 patients with metabolically healthy obesity (MHO), and 76 patients with metabolically unhealthy obesity (MUHO), bacterial DNA was isolated from stool samples, and the 16S rRNA gene was sequenced. The metabolic profile of the microbiota predicted by PICRUSt2 (https://huttenhower.

Effects of a Short-Term High-Fat Diet on Microbiota Biodiversity of the Small and Large Intestines of C57BL/6SPF Mice.

Long-term high-fat diet (HFD) promotes the formation of excess body weight and disorders of lipid metabolism and causes persistent dysbiotic changes in the intestinal microbial community. Changes in eating behavior, endocrine and immune functions of the host are associated with changes in the structure and functional activity of microbial communities. Short-term HFD may also influence the composition and function of the intestinal microbiota, but data on this issue are limited, and most papers are focused on the study of the large intestinal microbiota.

Plain-nosed bats (family Vespertilionidae) as a possible reservoir of lyssaviruses and coronaviruses in Western Siberia and the south of European Russia.

The review presents current data on the chiropterofauna inhabiting Western Siberia and the south of the European part of Russia. A general description of the genus of lyssaviruses and the family of coronaviruses is given. The potential for virus carriage in relation to lyssaviruses and coronaviruses in bat populations of two geographically distant regions is considered.
