An Overview of Macrolide Resistance in Streptococci: Prevalence, Mobile Elements and Dynamics

open access: yes, 2022
Streptococcal infections are usually treated with beta-lactam antibiotics, but, in case of allergic patients or reduced antibiotic susceptibility, macrolides and fluoroquinolones are the main alternatives.

Population-level macrolide consumption is associated with clarithromycin resistance in Helicobacter pylori: An ecological analysis

open access: yesInternational Journal of Infectious Diseases, 2019
Bystander selection has been shown to result in strong population-level correlations between the level of antimicrobial consumption in the general population and resistance to that antimicrobial or similar antimicrobials in a range of bacteria.

Noncanonical Peloruside A Biosynthesis by an Uncultivated Verrucomicrobiota Symbiont

open access: yesAngewandte Chemie, EarlyView.
Noncanonical biochemistry of the peloruside PKS characterized in this work, comprising double bond generation by a noncanonical tridomain (blue), acetyl‐CoA recycling (orange), and proofreading systems (purple and yellow). The Z‐double bond is installed by TEB1 through O‐acetylation and acetate elimination. The acyl ligase PelB (AL, orange) selectively

Radiologic findings as a determinant and no effect of macrolide resistance on clinical course of Mycoplasma pneumoniae pneumonia

open access: yesBMC Infectious Diseases, 2017
Background With the emergence of macrolide resistance, concerns about the efficacy of macrolides for the treatment of Mycoplasma pneumoniae (MP) pneumonia in children have been raised.

Effects of macrolides on pneumolysin of macrolide-resistantStreptococcus pneumoniae [PDF]

open access: yesEuropean Respiratory Journal, 2006
To clarify the discrepancy between increasing resistance and conservative clinical effects of macrolides on macrolide-resistantStreptococcus pneumoniae, the authors evaluated the effects of sub-minimum inhibitory concentrations of macrolides on pneumolysin.In vitro,S.

Phenotypic characterization of Macrolide-Lincosamide-Streptogramin B resistance in Staphylococcus aureus

open access: yes, 2021
Staphylococcus aureus (S.aureus) is a prevalent organism causing infections in the community and hospital. A variety of antibiotics are used, including the Macrolide-Lincosamide-StreptograminB (MLSB) family of antibiotics in which clindamycin is the ...

Phenotypes and genotypes of macrolide-resistant Streptococcus pneumoniae in Serbia [PDF]

open access: yesArchives of Biological Sciences, 2014
Although macrolides are widely used for treating pneumococcal infections, an increase in macrolide resistance might compromise their use. The objective of this study was to determine the prevalence of macrolide-resistant phenotypes and genotypes

Nomenclature for Macrolide and Macrolide-Lincosamide-Streptogramin B Resistance Determinants [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 1999
Macrolides are composed of 14 (erythromycin and clarithromycin)-, 15 (azithromycin)-, or 16 (josamycin, spiramycin, and tylosin)-membered lactones to which are attached amino and/or neutral sugars via glycosidic bonds. Erythromycin was introduced in 1952 as the first macrolide antibiotic.

High-Level Macrolide Resistance Due to the Mega Element [mef(E)/mel] in Streptococcus pneumoniae

open access: yesFrontiers in Microbiology, 2019
Transferable genetic elements conferring macrolide resistance in Streptococcus pneumoniae can encode the efflux pump and ribosomal protection protein, mef(E)/mel, in an operon of the macrolide efflux genetic assembly (Mega) element- or induce ribosomal ...
