antimicrobial resistance

This review aims to describe the microbiological characteristics, resistant features and pathogenic potential of Achromobacter spp. Achromobacter as an opportunistic pathogen can cause severe and even fatal infections. The current knowledge about …

Objective. To assess antimicrobial susceptibility, presence of resistance genes and determine the phenotypic groups of K. pneumoniae, P. aeruginosa and A. baumannii isolated from blood and cerebrospinal fluid of children with nosocomial infections in intensive care units from 2014 to 2020. Materials and Methods. Minimum inhibitory concentrations of antibiotics were determined using the serial broth microdilution method. The identification of genes encoding the production of carbapenemases was carried out using hybridization fluorescence detection.

This article presents a review of currently available data on etiology and antimicrobial resistance in surgical site infections (SSI) following cardiac surgery. Author performed analysis of the references on etiology and antimicrobial resistance in …

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.

Objective. To evaluate frequency and intensity of cefazolin inoculum effect among methicillin-susceptible staphylococci isolated from patients with skin infections. Materials and Methods. A total of 80 methicillin susceptible isolates of Staphylococcus aureus were identified by cefoxitin disk-diffusion test and negative results of real-time PCR for mecA gene. Inoculum effect was measured by broth microdilution test with two inocula with concentrations of 5 × 105 CFU/mL and 5 × 107 CFU/mL.

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.

Objective. To assess the etiology of infections, microbial associations and antimicrobial resistance in a burn intensive care unit. Materials and Methods. A microbiological study of 1322 biological samples from 195 patients with extensive burns included 479 blood samples, 82 respiratory samples, 326 urine samples, and 435 wound samples. Antimicrobial susceptibility testing was performed, and coefficients of constancy and associativity (CA), as well as the Jaccard coefficient were calculated. Results. The etiology of infections was represented by: Pseudomonas aeruginosa – 23%, Acinetobacter baumannii – 19.

The title of this review “War and peace” is not accidental and the analogies with a well-known literary masterpiece have absolutely justified ground. As in the case of Lev Tolstoy’s novel this title has a profound philosophical meaning, although at …

The article presents a critical analysis of antibiotic usage tactics in the treatment of patients with COVID-19 existing in Russian and foreign healthcare, and discusses the possible causes of unjustified antibiotic aggression in this category of …

Objective. To study the possibility of transferring multidrug resistant microorganisms through healthcare workers’ cell phones between medical institutions in Khabarovsk. Materials and Methods. It was a comparative prospective study to assess contamination of cell phones with multidrug-resistant microorganisms in a population (n = 30) and among intensive care unit (ICU) physicians (n = 60) in medical institutions. Antimicrobial susceptibility testing was performed by disc-diffusion method. A total of 514 healthcare workers from medical institutions of Khabarovsk were interviewed.
