Cultivation and molecular characterization of complete genome sequences of M. pneumoniae isolated in Russia

Objective. In 2023–2014, a significant increase in the incidence of pneumonia caused by M. pneumoniae has been reported in Russia and China. Despite being one of the primary causative agents of community-acquired lower respiratory tract infections in children, due to the difficulties in obtaining a culture of this pathogen, the amount of genomic data on M. pneumoniae is currently extremely limited, with fewer than 300 genomic sequences available, of which only 79 are complete.

Mycoplasma pneumoniae – modern data on the structure, molecular biology and epidemiology of the pathogen

Mycoplasma pneumoniae is a common etiologic agent of respiratory tract infections and communityacquired pneumonia (CAP) in children and adults. Recently, much new data on this pathogen, its molecular biology, cytoadherence and epidemiology have been …

Microbiological monitoring of COVID-19 patients in the ICU: a prospective observational study

Objective. To study spectrum of pathogens and the time to colonization of respiratory samples in patients with severe and critical COVID-19 as well as to analyze incidence of nosocomial infections and structure of prescribed antibacterial drugs. Materials and Methods. The prospective observational study included patients aged 18 years and older with confirmed severe and critical COVID-19 from December 2021 to February 2022. During the first 48 hours and then every 2–3 days of hospitalization, a respiratory sample was collected: sputum, tracheal aspirate (if intubated), bronchoalveolar lavage (if bronchoscopy was performed) for microscopy and microbiological examination.

COVID19 pandemic is a «pandemic» of antimicrobial therapy

The article presents a critical analysis of antibiotic usage tactics in the treatment of patients with COVID-19 existing in Russian and foreign healthcare, and discusses the possible causes of unjustified antibiotic aggression in this category of …

The prevalence of circulating S. pneumoniae serotypes in people older than 18 years: healthy carriers, patients with acute otitis media, community-acquired pneumonia, and invasive pneumococcal infections (epidemiological study «SPECTRUM»)

Objective. To estimate the prevalence of S. pneumoniae serotypes in adults aged of 18 years and older, including healthy carriers and patients with acute otitis media (AOM), community-acquired pneumonia (CAP) and invasive pneumococcal infection (IPI). Materials and Methods. A total of 230 isolates of S. pneumoniae from 10 centers were included in the study from 01.06.2019 to 01.10.2019. Re-identification and typing using real-time PCR with 22 primer pairs were performed in the central laboratory (Institute of Antimicrobial Chemotherapy, Russia).

Bacterial infections in patients with liver cirrhosis

Patients with liver cirrhosis are at substantial risk of bacterial infections. Bacterial complications account for more than 30% of hospitalizations and contribute significantly to mortality among cirrhotic patients. The most common bacterial …

A Clinical Case of Acute Herpesvirus and Pneumocystis Co-infection in a Patient with Progressive Pulmonary Tuberculosis

This article describes a clinical case of fatal polymicrobial pneumonia in a patient with progressive pulmonary tuberculosis. The clinical case represents a co-infection with tuberculosis, viral and pneumocystis infection in a HIV-uninfected patient …

Use of PCR for Diagnosis of Legionella Infection in Hematological Patients

Objective. To assess efficacy of PCR for detection of Legionella in bronchoalveolar lavage (BAL) fluid obtained from hematological patients with pneumonia and acute respiratory failure. Materials and Methods. A total of 79 BAL samples collected from the hospitalized hematological patients with pneumonia and acute respiratory failure (during the 2011–2014) were analyzed using PCR. All BAL samples have been tested for legionellosis by culture immediately after collection, and then stored at –70 °C.

Administration of Antimicrobials into Respiratory Tract: Methods to Improve Efficacy in the Treatment of Hospital-Acquired Pneumonia

Despite the availability of substantial theoretical benefits, the method of antibacterial administration via the respiratory tract to treat acute pneumonia has yet to be widely implemented in clinical practice. The introduction of the method is …
