Characterization of genetic diversity of the Klebsiella pneumoniae strains in a Moscow tertiary care center using next-generation sequencing

Objective. To study genetic diversity of Klebsiella pneumoniae strains obtained in the National Medical and Surgical Center named after N.I. Pirogov (Moscow) using next-generation sequencing. Materials and Methods. A total of 19 isolates of K. pneumoniae were included in the study (18 – from patients and 1 – from nosocomial environment). The strains were isolated from January 30 to October 9, 2017 and phenotypically showed multi-drug resistance. DNA sequencing of the strains was performed on the Illumina HiSeq1500 instrument using the Illumina HiSeq PE Rapid Cluster Kit v2 and Illumina HiSeq Rapid SBS Kit v2 kits.

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.
