Genomic properties in Achromobacter spp. strains from cystic fibrosis patients in Russia

Objective. To determine species, sequence-types, antimicrobial resistance and virulence genes in Achromobacter spp. isolates obtained from cystic fibrosis (CF) patients in Russia. Materials and Methods. Samples (sputum, nasopharyngeal swab) from 168 CF patients from 48 regions were studied. Whole-genome sequencing (WGS) was performed on MGISEQ-2000 platform. SPAdes software, Galaxy, ResFinder, Integrall, PubMLST were used for analysis of WGS data. Results. A total of 18 strains of Achromobacter spp. were isolated from 16 of 168 CF patients.

Cytomegalovirus after allogeneic hematopoietic stem cell transplantation: reactivation or reinfection?

Objective. To determine type of cytomegalovirus (CMV) infection (reactivation of a virus strain that was present before transplantation or re-infection with another virus strain) in allogeneic hematopoietic stem cell recipients by sequencing. Materials and Methods. Clinical and laboratory data of 179 recipients of allogeneic hematopoietic stem cells collected from 2014 to 2018 were analyzed for CMV DNA in clinical specimens before and after transplantation. A total of 14 patients (28 samples) were included in the study.

The prevalence and antimicrobial susceptibility of circulating S. pneumoniae serotypes in adult population in Russia (epidemiological study «SPECTRUM»)

Objective. To estimate prevalence and antimicrobial susceptibility of circulated S. pneumoniae serotypes in adult population in different regions of the Russian Federation. Materials and Methods. A total of 500 isolates of S. pneumoniae obtained from patients with invasive pneumococcal disease (IPD), community-acquired pneumonia (CAP), sinusitis/acute otitis media (AOM) and healthy carriers from 29 centers were included in the study from 01 June 2019 to 15 January 2020. Re-identification, typing using real-time PCR with 27 primer pairs and antimicrobial susceptibility testing were performed in the central laboratory by standardized methods.

Investigation of a candidemia outbreak caused by C. parapsilosis in a pediatric hematology/oncology center

Objective. To investigate a candidemia outbreak caused by C. parapsilosis in a clinical unit of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology (NMRC PHOI). Materials and Methods. A total of 35 isolates of C. parapsilosis obtained from clinically significant specimens and swabs, including hands of nursing staff of the NMRS PHOI, over the 2018-2020 were genotyped in this retrospective study. Identification of C. parapsilosis isolates was performed by microbiological methods.
