The intestinal health of poultry is of great importance for birds’ growth and development; probiotics-driven shifts in gut microbiome can exert considerable indirect effect on birds’ welfare and production performance. The information about gut microbiota of ducks is scarce; by using high throughput metagenomic sequencing with Illumina Miseq we examined fecal bacterial diversity of Peking ducks grown on conventional and Bacillus-probiotic-enriched feed. The probiotic supplementation drastically decreased the presence of the opportunistic pathogen Escherichia/Shigella, which was the major and sole common dominant in all samples. Seventy other bacterial species in the ducks’ fecal assemblages were found to have probiotic-related differences, which were interpreted as beneficial for ducks’ health as was confirmed by the increased production performance of the probiotic-fed ducks. Bacterial α-biodiversity indices increased in the probiotic-fed group. The presented inventory of the duck fecal bacteriobiome can be very useful for the global meta-analysis of similar data in order to gain a better insight into bacterial functioning and interactions with other gut microbiota to improve poultry health, welfare and production performance.

The beginning of 2020 was characterized by the development of a new coronavirus pandemic (COVID-19). Information about the epidemiology, etiology, pathogenesis, clinical and laboratory diagnostics, as well as prevention and therapy for this disease is constantly being expanded and reviewed. The COVID-19 pandemic creates the need for the emergence of new conditions of specialized care for patients with heart rhythm and conduction disorders [1]. These recommendations are intended for general practitioners, internists, cardiologists, electrophysiologists/arrhythmologists, cardiovascular surgeons, functional diagnostics doctors, anesthesiologists-resuscitators, laboratory diagnostics specialists, health care organizers in the system of organizations and healthcare institutions that provide specialized care to patients with heart rhythm and conduction disorders.

This article reviews current approaches to diagnosis and determination of the individual risk of patients with acute coronary syndrome without ST-segment elevation. Guidelines for determining the choice of treatment strategy and the time slots for its implementation are discussed. We describe the technical features of the implementation of interventional treatment in this group of patients; the choice of methods of myocardial revascularization is discussed.
