Etiology of community-acquired pneumonia in the military personnel

Objective. To assess the etiology of community-acquired pneumonia (CAP) in the army recruits using a polymerase chain reaction (PCR) assay. Materials and Methods. Sputum, blood, bronchoalveolar lavage samples and oropharyngeal swabs collected from 255 hospitalized army recruits with radiographically confirmed diagnosis of CAP were tested by PCR assay. The comparator group included 270 otherwise healthy recruits. Detection of Streptococcus pneumoniae, Haemophilus influenzaе, Mycoplasma pneumoniae, Chlamydophila pneumoniae, Chlamydophila psittaci, Legionella pneumophila, adenoviruses, Herpes simplex virus I/II, cytomegalovirus was performed by PCR using commercial AmpliSens kits and GenPak DNA PCR test.

Real-Time PCR for the Diagnosis of Tick-Born Infections

Overall 842 cases of admission due to tick bites in Irkutsk area during 2014 were analyzed. Detection of DNA/RNA of the tick-born encephalitis virus, Lyme borreliosis, monocytic ehrlichiosisand granulocyticanaplasmosis in the human serum and in the …

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.

Development of Chlamydial Arthritis Model in Rats

Objective. To develop and characterize experimental model of chlamydial arthritis in rats. Materials and Methods. Wistar male rats received an intra-articular injection of 0.15–0.20 ml of purified elementary bodies of Chlamydophila (Chlamydia) trachomatis L2/Bu-434 or Chlamydophila (Chlamydia) muridarum Nigg. Animals were divided into two groups: young rats (body weight: 350-380 g) and adult rats (body weight: 450–500 g). Results. No changes in the affected joints were observed in rats infected with C.

PCR-based Identification and Serotyping of Russian Streptococcus pneumoniae Strains
