BACKGROUND: It is known that the gut microbiome of a healthy person affects the process of COVID-19 after getting infected with SARS-CoV-2 virus. It is also believed that colchicine can alleviate the severity of COVID-19. OBJECTIVE: Current investigations aimed to evaluate the associations between the baseline gut microbiota composition of healthy and Familial Mediterranean fever (FMF) - carrier Armenian men populations, and the severity of the COVID-19 disease after their infection with the SARS-CoV-2...

Aim - in complex to evaluate different types of female vaginal biocenosis on the background of contraceptives usage in order to detect implant-associated infection. Clinical status, features of vaginal microflora and formation of biofilms were assessed in 64 women of reproductive age, who had inert intrauterine device (IUD) of the second generation for a period of from 5 months to 8 years. pH of vaginal secretion was measured by the test strips CITOLAB (Farmasko, Ukraine). The condition of vaginal biocenosis was assessed according to «Femoflor-Screen», polymerase chain reaction in real time...

Aging-associated alterations in composition, diversity and functional features of intestinal microbiota are well-described in the modern literature. They are suggested to be caused by an age-related decline in immune system functioning (immunosenescence) and a low-grade chronic inflammation (inflammaging), which accompany many aging-associated pathologies. The microbiota-targeted dietary and probiotic interventions have been shown to favorably affect the host health and aging by an enhancement of antioxidant activity, improving immune homeostasis, suppression of chronic inflammation, regulation of fat deposition and metabolism and prevention of insulin resistance...

A priority clinical and research agenda in mood and anxiety disorders is to identify determinants that influence illness trajectory and outcome. Over the past decade, studies have demonstrated a bidirectional relationship between the gut microbiome and brain function (i.e., the microbiota-gut-brain axis). Probiotic treatments and developmental analysis of the microbiome may provide potential treatments and preventative measures for depressive and anxiety disorders. This systematic literature review aims to identify original studies linking the gut microbiota to major depressive disorder and anxiety disorders...

Mucosal barriers encounter an environment that is rich in pathogens that possess mechanisms for invading mucosal tissues. These barriers also encounter innocuous antigens, such as foods, airborne antigens, and microbiota. The mucosa has developed a sophisticated immune system that can mount robust immune responses against pathogenic antigens, while maintaining mucosal tolerance against non-pathogenic antigens. Accumulating evidence indicates that the mucosal epithelium, dendritic cells, and a subtype of T cells with regulatory properties play important roles in the development and maintenance of mucosal tolerance...
