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.

Whole genome sequencing of Mycoplasma hominis strains resistant to ciprofloxacin

In order to determine molecular mechanisms of resistance to ciprofloxacin, clinical isolates of Mycoplasma hominis (2 strains) obtained from women with pelvic inflammatory disease were investigated. Whole genome sequencing was performed using a …

Susceptibility testing of Candida glabrata clinical strains to echinocandins using SensititreTM YeastOneTM system

Objective. To determine susceptibility of C. glabrata isolates to anidulafungin, caspofungin and micafungin using the SensititreTM YeastOneTM system. Materials and Methods. C. glabrata isolates were taken prospectively from clinical specimens or from strains collections in the participating sites. Susceptibility determination was performed using SensititreTM YeastOneTM (YO10 panel) according to the manufacturer’s guidance, and results were interpreted with M27-A3 CLSI guidelines. Susceptibility of C. glabrata to fluconazole was also determined in order to assess possible correlations of echinocandins and fluconazole minimal inhibitory concentrations (MICs) in resistant strains.

Mechanisms and regulation of antimicrobial resistance in Pseudomonas aeruginosa

Pseudomonas aeruginosa is a dangerous opportunistic pathogen. One of the most negative clinically significant features of P. aeruginosa is associated with the rapid acquisition of antimicrobial resistance. This review provides an analysis of current …

Analysis of effectiveness criteria in pharmacoeconomic studies of antimicrobial agents proposed for inclusion in the Russian essential drug list in the 2014 -2016

Objective. To estimate proportion of hard and surrogate endpoints used as effectiveness criteria in pharmacoeconomic studies of antimicrobial drugs. Materials and Methods. The pharmacoeconomic studies of 30 antimicrobial agents proposed for inclusion in the Russian essential drug list in the 2014-2016 were reviewed. Results. A total of 47 effectiveness criteria were analyzed, of them 40.4% were hard endpoints. Two studies of antifungal drugs used the hard endpoints only. The hard endpoints were used in 58.

Four cases of resistance mutations in 23S rRNA gene in Mycoplasma pneumoniae isolated from the hospitalized military personnel

Mycoplasma pneumoniae is a bacterial pathogen cause of upper and lower respiratory tract infections, transmitted by airborne droplets, causing outbreaks of pneumonia mainly in closed groups. According with recommendations, M. pneumoniae infections …

Carbapenemase-producing Gram-negative bacteria in the Russian research center of radiology and surgical technologies

Objective. To assess an incidence rate of carbapenemase-producing Gram-negative bacteria isolated from patients in the RRCRST. Materials and Methods. The clinical Gram-negative isolates obtained from patients hospitalized to the RRCRST over the period of February 2014 to April 2016 were tested. A screening for carbapenem resistance was performed by culture on chromogenic media, and species identification was made using MALDI-TOF massspectrometry. Susceptibility of Gram-negative bacteria to antimicrobial agents was determined using VITEK-2.

Candida glabrata Resistance to Echinocandins Associated with FKS Genes Mutations: How Urgent is the Problem?

The resistance of the systemic Candida infections causative agents is a cornerstone of the selection of an effective therapy. But if before the problem was limited to resistance to azole antifungals, then by now we have enough data about cases of …

Comparative In Vitro Activity of Native Honey and Commercially Available Honey Preparations Against Bacterial Isolates with Extreme Antimicrobial Resistance Phenotypes

This paper presents data on in vitro activity of native honey against bacterial isolates with extreme resistance phenotypes. Comparison of antimicrobial activity of foreign honey preparations approved for the local treatment of infections with that …

Genotyping Analysis of Nosocomial Acinetobacter baumannii Strains

The problem of genotypic variety of Acinetobacter baumannii isolated from patients with healthcare associated infections (HCAIs) are discussed. Carbapenemresistant strains, which are predominant in the study region, were shown to belong to the …
