Macrolide and fluoroquinolone resistance in Mycoplasma genitalium isolated from pregnant women in Russia and Belarus

Objective. To study epidemiology of resistance to macrolides and fluoroquinolones in Mycoplasmagenitalium isolated from pregnant women in Russia and Belarus. Materials and Methods. A total of 107 M. genitalium DNA samples isolated from pregnant women in Russia (n = 58) and Belarus (n = 49) was included in the study. In order to detect markers of macrolide or fluoroquinolone resistance, polymerase chain reaction in real time with the effect of quenching fluorescence of the probe by a primer was used.

Adverse drug reactions of macrolide therapy: analysis of spontaneous reports according to the Pharmacovigilance system

Objective. To perform pharmacoepidemiological analysis of spontaneous reports of adverse drug reactions (ADRs) occurred during macrolide group antibiotics prescription and registered in the “Pharmacovigilance 2.0” subsystem of the Federal Service for Surveillance in Healthcare. Materials and Methods. A retrospective pharmacoepidemiological analysis of spontaneous reports of ADRs arising from the use of all macrolide and azalide antibiotics registered in Russia and registered in the electronic database of the “Pharmacovigilance 2.0” subsystem of the Federal Service for Surveillance in Healthcare for the period from 01.

Prevalence of the A2058G mutation in 23S rRNA gene, which determines Treponema pallidum macrolide resistance in Russian population

Objective. To investigate prevalence of the A2058G mutation in the Russian population of T. pallidum and its association with molecular subtypes. Materials and Methods. We analyzed DNA isolated from 325 samples of clinical material obtained from patients of dermatovenereological treatment and prophylactic institutions in 6 federal districts of the Russia in the period from 2014 to 2021. Patients were diagnosed with primary syphilis of the genital organs, primary syphilis of other sites, or secondary syphilis of the skin and mucous membranes.

Monitoring of macrolide resistanceassociated mutations in Mycoplasma genitalium in Russia

Objective. To determine spectrum and prevalence of genetic determinants of resistance to macrolides in Mycoplasma genitalium in a Russian patient population. Materials and Methods. A total of 873 M. genitalium-positive samples from five geographical regions of Russia were investigated over the period of 2009–2019 using the previously developed protocol of real-time polymerase chain reaction (allows detecting any nucleotide substitutions in the 23S rRNA gene of M. genitalium at positions 2058, 2059, and 2611).

Potentiation of antimicrobial activity of colistin with antibiotics of different groups against multidrug- and extensively drug-resistant strains of Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa

Objective. To reveal antibiotics being capable of potentiating the antimicrobial activity of colistin against multidrug- and extensively drug-resistant strains of Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa. Materials and Methods. The minimum inhibitory concentrations (MIC) of colistin alone and in combination with fixed concentrations of antibiotics of different groups were determined for 272 multidrug- and extensively drug-resistant strains of K. pneumoniae, A. baumannii and P. aeruginosa. Bactericidal activity of colistin, carbapenems, clarithromycin and their combinations were also determined at fixed PK/PD breakpoint concentrations of antibiotics.

The rates of mutations associated with macrolide resistance in Mycoplasma genitalium among patients with non-gonococcal sexually transmitted infections in Smolensk and Tula

Objective. In this study, we examined the prevalence of macrolide-resistant M. genitalium in two Russian cities, Smolensk and Tula, between 2013 and 2017. Materials and Methods. DNA’s samples were isolated from urethral and cervicovaginal swabs using primary screening and tested for macrolide resistance-associated mutations by real-time PCR. This technology makes it possible to identify any nucleotide substitutions in the 23S rRNA M. genitalium gene at positions 2058, 2059, 2611 M.

Potential for the use of macrolides in the antimicrobial therapy of severe community-acquired pneumonia in adults

This paper presents mechanism of action and antimicrobial spectrum of macrolides as well as the known acquired resistance mechanisms in the common pathogens causing community-acquired pneumonia, such as Streptococcus pneumoniae and Mycoplasma …

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 …
