Streptococcus pneumoniae

Pneumococcal conjugate vaccines contain a limited number of serotype-specific antigens of S. pneumoniae. It is important for vaccination programmes effectiveness assessment to control a variety of circulating S. pneumoniae serotypes. This review …

Objective. To determine in vitro activity of thiamphenicol and other clinically available antimicrobials against clinical isolates of Haemophilus influenzae, Streptococcus pneumoniae and Streptococcus pyogenes. Materials and Methods. We included in the study 875 clinical isolates from 20 Russian cities during 2018–2019. Among tested strains, 126 were H. influenzae, 389 – S. pneumoniae, 360 – S. pyogenes. Antimicrobial susceptibility testing was performed using broth microdilution method according to ISO 20776-1:2006. AST results were interpreted according to EUCAST v.

The review discusses national clinical practice guidelines for pneumococcal vaccination in different countries, existing approaches to adult immunization, and highlights key results of the most significant clinical studies and metaanalyses on the …

Objective. To evaluate antimicrobial resistance patterns of clinical Streptococcus pneumoniae isolates from different regions of Russia during 2014–2017. Materials and Methods. We included in the study 519 clinical S. pneumoniae isolates from 18 Russian cities. Susceptibility testing was performed by reference broth microdilution method (ISO 20776-1:2006). Susceptibility testing results were interpreted according to EUCAST v.9.0 breakpoints. Results. Using EUCAST non-meningeal interpretation criteria, 65.1% of isolates tested were susceptible (S) to penicillin; in addition 28.

Objective. To study antimicrobial susceptibility of Streptococcus pneumoniae clinical isolates obtained from the patients with community-acquired pneumonia in the Central Kazakhstan. Materials and Methods. A total of 186 clinical strains of S. pneumoniae were obtained from the patients with respiratory tract infections in the Central Kazakhstan over the period of 2012–2017. Antimicrobial susceptibility was determined by disk-diffusion method. The isolation and identification of pathogens was performed by routine methods. Antimicrobial (oxacillin, vancomycin, clindamycin, azithromycin, chloramphenicol, tetracycline, rifampin, levofloxacin, linezolid, trimethoprim/sulfamethoxazole) susceptibility testing was performed and interpreted according to CLSI criteria (M100-24).

Objective. To study antibiotic resistance and its association with serotypes of Streptococcus pneumoniae isolated from hospitalized children with community-acquired ENT infections in Belarus during 2013-2016 and to analyze a potential for the use of different antibiotic classes in the treatment of those infections. Materials and Methods. A total of 115 strains isolated from children with acute otitis media and 18 strains isolated from children with acute rhinosinusitis were tested. Antimicrobial susceptibility testing was performed by a broth microdilution method.

After the introduction of the conjugated 7-valent pneumococcal vaccine (PCV7) the incidence of infections, caused by non-vaccine serotypes of S. pneumoniae, especially by 19А serotype, significantly increased. But in few countries similar phenomenon …

Objective. Due to high activity against Streptococcus pneumoniae ceftaroline fosamil (CF) presents a good option for the treatment of adults with pneumococcal communityacquired pneumonia (PCAP) requiring parenteral antibacterial therapy. We aimed to assess cost-effectiveness of CF for the treatment of PCAP in a multi-field hospital in Russia from a societal perspective. Materials and Methods. Decision tree model based on the results of two 3rd phase clinical trials (FOCUS 1, FOCUS 2) was created to represent a standard approach to the management of hospitalised patients with PCAP and estimated outcomes including possible recurrence of infection, direct and delayed attributive mortality in case of initial therapy with CF 600 mg BID vs.

Streptococcus pneumoniae strains isolated from children of Krasnoyarsk (Siberia, Russian Federation) were examined. Authors determined Streptococcus pneumoniae serotypes and antimicrobial resistance. 16.7% of strains were multiple resistant with high …

The techniques for PCR-based identification and serotyping of Streptococcus pneumoniae were optimized for using in Russian epidemiologic situation. One hundred and thirteen strains isolated from children under 5 years of age in 15 Russian cities were …
