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 …

Emerging Concepts in Use of Macrolides in Pregnancy and Lactation

This paper reviews general issues of the use of antimicrobial agents in pregnant women. Currently available data on safety of macrolides during pregnancy and lactation are considered with the focus on several indications for their therapeutic and …

Potential for Use of Spiramycin in Clinical Practice

Spiramycin, natural 16-membered macrolide antibiotic, was discovered in 1954. This antimicrobial agent is at least non-inferior to and has some advantages over the currently available macrolides in spectrum of activity, pharmacological properties, …

Asthma associated with Chlamydophila pneumoniae-infection

The present open-label, randomized, comparative study of efficacy of 8-week Azithromycin therapy in mildto-moderate stable asthma included 71 patients. After evaluation for C. pneumoniae infection by serologic tests, patients where randomized into 4 …
