MODELING REORGANIZATION OF PCF10-INDUCED COMPLEX STRUCTURES IN ENTEROCOCCUS FAECALIS UNDER ERYTHROMYCIN TREATMENT
… packing above the rigid base. Under treatment by erythromycin, E. faecalis OG1RF(pCF10) is shown to undertake a remodeling process where aggregated regions of the complex structures increase, and the total bacterial population doubles. In this dissertation, we present a series of models developed …

Characterization of 50S Ribosomal Subunit Assembly Inhibition in Erythromycin Treated <em>Escherichia coli</em> Cells.
<p>Erythromycin has long been recognized for its ability to inhibit protein synthesis by interfering with mRNA translation on the bacterial ribosome. We have recently shown that erythromycin also inhibits the assembly of the 50S ribosomal subunit in growing bacterial cells. The nature of this …

Non-Antibiotic Effects of Macrolide Antibiotics of the Oleandomycin-Erythromycin Group With Special Reference to Their "Steroid-sparing" Effects
Previous papers in the literature reported the effectiveness of triacetyloleandomycin, a macrolide antibiotic, in the treatment of bronchial asthma. The beneficial effects were attributed to the antimicrobial characteristics of this compound. However, the antiasthmatic activity of the drug was …

Mecanismos de resistencia a antibióticos macrólidos, lincosamidas y estreptograminas en streptococcus y enterococcus
… as temporary evolution and clonal diversity for erythromycin-resistant Streptococcus isolates. A new gene that we called msrC was described for an enterococcal species. Conclusions: High erythromycin resistance rates were detected for beta-haemolytic group A, B, C and G Streptococcus isolates in …

Studies on a 50S Ribosomal Precursor Particle as a Substrate for <em>erm </em>E Methyltransferase Enzyme in <em>Staphylococcus aureus </em>.
<p>Erythromycin is a macrolide antibiotic that inhibits not only mRNA translation but also 50S ribosomal subunit assembly in bacterial cells. An important mechanism of erythromycin resistance is the methylation of 23S rRNA by <em>erm</em> methyl transferase enzymes. We are interested in …

Macrolide and lincosamide resistance patterns in invasive and colonizing group B streptococcus isolated in Belgium
Increase of erythromycin and clindamycin resistance among group B Streptococcus (GBS) have been reported worldwilde. Therefore phenotypical and molecular surveillance of macrolides and lincosamides resistance patterns in Belgium has been conducted. Antimicrobial susceptilities to erythromycin and …

Structural Studies of Enzymes Involved in Drug Resistance and Antibiotic Biosynthesis
… of phylogeny. The macrolide antibiotic erythromycin can be enzymatically degraded by strains carrying the ereB locus that codes for erythromycin esterase type B and confers high level resistance to this widely used antibiotic. We have determined high resolution crystal structures of …

Does the human skin microbiome adapt to antibiotic exposure?
… were firstly susceptible to antibiotics such as erythromycin and doxycycline, and later formed adaptive resistance. Erythromycin adapted strains were found to be resistant to erythromycin and cross- resistant to doxycycline based on both disk diffusion assay and MIC results. Doxycycline adapted …

A Study of Antibiotic Resistance Plasmids in Fresh Produce and In Wastewater Environments Using Functional Approaches, Comparative Genomics and Abundance Analysis
… bacteria. Ciprofloxacin, meropenem and erythromycin are important clinical antibiotics due to their broad applications in the treatment of Gram-positive and Gram-negative infections. The capacity to capture, mobilise and control the expression of resistance genes is an important factor …

Nasopharyngeal colonization dynamics with Streptococcus pneumoniae and associated antimicrobial resistance in a South African birth cohort
… (n = 528). The prevalence of penicillin, erythromycin, and cotrimoxazole non-susceptibility was 19% (147/760; 95% CI 17-22%) (3% resistant), 18% (136/760; 95% CI 15-21%) (14% resistant) and 45% (344/760; 95% CI 42-49%) (36% resistant), respectively. The predominant …

Streptococcus agalactiae bei Schwangeren und Neugeborenen : Prävalenz und Transmission sowie Serotypen und molekulargenetische Charakteristika
… wobei besonders die Resistenz gegen Erythromycin von Bedeutung war. Im letzten Schritt wurden die Genotypen jener Isolate analysiert, die eine solche Erythromycin-Resistenz aufwiesen. Bei ihnen wurde nach den Genen erm(TR), erm(B), mef(A) sowie tet(M) und int-TN gesucht. <br> …
