Measles virus causes an acute infectious disease with high contagiousness. It is possible to limit the spread of measles virus only with a sufficiently wide coverage of the population by vaccination. Despite the success of measles elimination …

This paper provides a review of the largest studies (over the period of 2017 to 2022) on the use of fecal microbiota transplantation (FMT) for the treatment of patients with recurrent *Clostridioides difficile*associated diarrhea (CDAD), including …

This paper provides a review of the largest studies (over the period of 2017 to 2022) on cost-effectiveness analysis of the recommended treatment algorithms for Clostridioides difficile infection in patients with antibiotic-associated diarrhea (AAD), …

Objective. To study risk factors, clinical and radiological features and effectiveness of the treatment of invasive aspergillosis (IA) in adult patients with COVID-19 (COVID-IA) in intensive care units (ICU). Materials and Methods. A total of 60 patients with COVID-IA treated in ICU (median age 62 years, male – 58%) were included in this multicenter prospective study. The comparison group included 34 patients with COVID-IA outside the ICU (median age 62 years, male – 68%).

Temperate bacteriophages are of interest as carriers and vectors of pathogenicity factors that determine an epidemic potential of opportunistic bacteria as well as biotechnology objects. This review describes studies of temperate bacteriophages …

Chronic obstructive pulmonary disease (COPD) is a serious problem for global health. Infectious agents play a main role in the development of COPD exacerbations. Bacterial colonization of the lower respiratory tract is common in patients with stable …

Objective. To assess the course and outcomes of COVID-19 in recipients of allogeneic and autologous hematopoietic stem cell transplant (HSCT). Materials and Methods. The retrospective study included 44 adult recipients (allogeneic – 33 [75%] and autologous – 11 [25%] of HSCT who diagnosed with COVID-19 after transplantation. Group mostly represented by acute leukemia – 18 (41%) and lymphoma – 10 (22.7%). The median follow-up time since the development of COVID-19 was 231 days (1–818 days), after HSCT – 507.

Objective. To determine resistant microorganisms carriage, the frequency and etiology of postoperative infectious complications in high-risk infants with congenital heart defects (CHD). Materials and Methods. The retrospective analysis included 489 patients admitted for surgical treatment for CHD. The median age was 0.23 (0–12) months. Swabs were taken from the oropharynx and rectum for microbiological examination no later than 72 hours after admission (a total of 978 samples). The growth of resistant microorganisms (ESBL and/or carbapenemase-producing Enterobacterales, resistant non-fermentative Gram-negative bacteria, MRSA and VRE) was recorded.

Objective. To study the prevalence of pneumocystosis among heart recipients (persons awaiting heart transplantation), persons with heart transplantation (patients with orthotopic heart transplantation) and to determine the role of pneumocysts in the etiology of bronchopulmonary complications in them. Materials and Methods. The paper presents an analysis of the results of a study of 94 samples of blood sera of patients who were treated at the Shumakov Institute of Transplantation and Artificial Organs of the Ministry of Health of Russia (Moscow).
