The first case of human invasion by in the European part of Russia.

The article presents a rare case of human invasion by the trematode in the European part of Russia. The diagnosis was established based on a parasitological study of flukes removed from the tonsils and pharynx of a 42-year-old woman, a resident of the Tambov region of Russia.

Novel Universal Recombinant Rotavirus A Vaccine Candidate: Evaluation of Immunological Properties.

Rotavirus infection is a leading cause of severe dehydrating gastroenteritis in children under 5 years of age. Although rotavirus-associated mortality has decreased considerably because of the introduction of the worldwide rotavirus vaccination, the global burden of rotavirus-associated gastroenteritis remains high. Current vaccines have a number of disadvantages; therefore, there is a need for innovative approaches in rotavirus vaccine development.

[A case of pleuropulmonary dirofilariasis caused by Dirofilaria repens. Case report].

The differential diagnosis of neoplasms of various localizations is the primary task in clinical practice of all physicians. We present a description of the case of invasion with Dirofilaria repens in the lung of a 68-year-old patient. In 2016 the patient was diagnosed with cancer of the left kidney and underwent a left-sided nephrectomy.

Cultivable Gut Microbiota in Synanthropic Bats: Shifts of Its Composition and Diversity Associated with Hibernation.

The role of bats in the global microbial ecology no doubt is significant due to their unique immune responses, ability to fly, and long lifespan, all contributing to pathogen spread. Some of these animals hibernate during winter, which results in the altering of their physiology. However, gut microbiota shifts during hibernation is little studied.

HIV-1 Drug Resistance among Treatment-Naïve Patients in Russia: Analysis of the National Database, 2006-2022.

In Russia, antiretroviral therapy (ART) coverage has significantly increased, which, in the absence of routine genotyping testing, could lead to an increase in HIV drug resistance (DR). The aim of this study was to investigate the patterns and temporal trends in HIV DR as well as the prevalence of genetic variants in treatment-naïve patients from 2006 to 2022, using data from the Russian database (4481 protease and reverse transcriptase and 844 integrase gene sequences). HIV genetic variants, and DR and DR mutations (DRMs) were determined using the Stanford Database.

[Comparative evaluation of the effectiveness of narlaprevir in the composition of interferon and interferon-free treatment regimens for patients with chronic hepatitis C].

Aim: Our aim was to give a comparative assessment of the effectiveness of using narlaprevir in combination with pegylated interferon-alpha-2a (Peg-IFN-alpha-2a) and interferon-free mode in patients with chronic hepatitis C (CHC).

Materials And Methods: The prospective cohort study included 187 patients infected with genotype 1b of hepatitis C virus. Of these, 107 (the 1st group of patients) received narlaprevir 200 mg once a day, ritonavir 100 mg once a day, Peg-IFN-alpha-2a 180 mkg subcutaneously once a week and ribavirin at a dose depending on body weight (10001200 mg per day) for 12 weeks, and then the standart "dual" therapy (Peg-IFN-alpha-2a + ribavirin) was continued until 24 weeks.

Gut microbiota of bats: pro-mutagenic properties and possible frontiers in preventing emerging disease.

Bats are potential natural reservoirs for emerging viruses, causing deadly human diseases, such as COVID-19, MERS, SARS, Nipah, Hendra, and Ebola infections. The fundamental mechanisms by which bats are considered "living bioreactors" for emerging viruses are not fully understood. Some studies suggest that tolerance to viruses is linked to suppressing antiviral immune and inflammatory responses due to DNA damage by energy generated to fly.

[Inguinal lymphadenitis due to invasion of Dirofilaria repens].

The paper presents the case of the right-sided inguinal inflammation of a lymph node as a result of invasion of Dirofilaria repens, the parasitic pathogen of subcutaneous dirofilariasis in animals of the canine family. The diagnosis was verified on the basis of the parallel application of morphological studies of cross sections of the nematode in histological samples and the molecular biological method polymerase chain reaction of scrapings of histological material. The localization of this helminth inside the cavities of the human body is extremely rare.

Description of the rare localization of Dirofilaria repens in human in the right inguinal lymph node.

D. repens is the causative agent of subcutaneous dirofilariasis in canine animals. In recent years, human invasion by this vector-borne helminthiasis has been recorded in many countries with temperate climate, but the localization of this helminth in the cavities of the human body is extremely rare.

Molecular Epidemiology of HIV-1 Subtype G in the Russian Federation.

Although HIV-1 subtype A has predominated in Russia since the end of the 20th century, other viral variants also circulate in this country. The dramatic outbreak of HIV-1 subtype G in 1988-1990 represents the origin of this variant spreading in Russia. However, full genome sequencing of the nosocomial viral variant and an analysis of the current circulating variants have not been conducted.

Clinical and laboratory features of human dirofilariasis in Russia.

The article presents the results of the prospective study of 266 patients with dirofilariasis who received medical and diagnostic assistance in Rostov Scientific Research Institute of Microbiology and Parasitology in Rostov-on-Don, Russia from 2000 to 2016. We have assessed the features of the dynamics of epidemiology of this infection in several territories of the Russian Federation, depending on the social structure of patients. Immature females of dirofilaria were found most commonly in humans (82.

Human subcutaneous/ocular dirofilariasis in the Russian Federation and Belarus, 1997-2013.

Objectives: This study was performed to determine the yearly frequency, trends in spread, and clinical-epidemiological characteristics of human subcutaneous/ocular dirofilariasis (HSOD) in the Russian Federation and Belarus.

Methods: The surveillance data of HSOD cases occurring between January 1997 and June 2013, obtained from the regional health administrations of the Russian Federation and Belarus, were analyzed. The spatial distribution of cases was assessed using a GIS map, and the clinical-epidemiological characteristics were defined using 719 cases for which information on anatomical location, age, sex, and area of residence was available.
