Antimicrobial susceptibility and association with serotypes of Streptococcus pneumoniae isolates in children with acute otitis media and acute sinusitis in Belarus

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.

Antimicorbial Susceptibility, Clonal and Serotype Diversity of Streptococcus pneumoniae Isolated from Children with Acute Otitis Media in Moscow

Objective. Streptococcus pneumoniae (pneumococcus) is the leading cause of acute otitis media (AOM) in children. Hereby, we describe antibiotic susceptibility, clonality, and serotype distribution of pneumococci isolated from the middle ear fluid (MEF) in children with AOM. Materials and Methods. MEF specimens from children ≤5 years of age with AOM were collected in 4 pediatric hospitals in Moscow in 2011–2013. Isolation and identification of pneumococcus was performed using standard microbiological procedures.

Serological Characteristics and Antimicrobial Susceptibility of Streptococcus pneumoniae Isolated from Children Under 5 Years and Patients >65 Years in Belarus and Ukraine

Objective. Objectives. To reveal serotypes of Streptococcus pneumoniaе isolated from patients with pneumococcal infections and from healthy carriers in Belarus and Ukraine. Materials and Methods. There were 314 strains of S. pneumoniae in this investigation, from patients and asymptomatic carriers at the age from 0 to 90 years. After re-identification and susceptibility testing to penicillin, serogroup and serotype was identified for each strain. Using this data the coverage of 7-, 10- and 13-vallent pneumococcal conjugate vaccines was determined.
