common infections encountered in children. Most bacterial infections are caused by Streptococcus pyogenes (1). In addition, resurgence of severe forms of disease caused by S. pyogenes has been detected in various parts of the world (2, 3). Although all S. pyogenes strains remain exquisitely sensitive to penicillin, erythromycin has been the drug of choice for individuals who cannot take penicil...

Streptococcus pyogenes is a significant pathogen of humans, annually causing over 700,000,000 infections and 500,000 deaths. Virulence in S. pyogenes is closely linked to mobile genetic elements like phages and chromosomal islands (CI). S. pyogenes phage-like chromosomal islands (SpyCI) confer a complex mutator phenotype on their host. SpyCI integrate into the 5' end of DNA mismatch repair (MMR...

Introduction & Objective: Teucrium polium belonging to Lamiaceae family has been widely used in traditional medicine for treatment of diseases. Regarding the existence of the active biological compounds in this plant, it seems that this plant has considerable antimicrobial ef-fects. The aim of this study is to investigate the antimicrobial effect of different concentra-tions of the aqueous an...

OBJECTIVES To type mef genes in a nationwide collection of clinical isolates of Streptococcus pneumoniae and Streptococcus pyogenes as well as pharyngeal carrier strains of viridans streptococci in Norway. METHODS Erythromycin-resistant mef-positive multilocus sequence-typed (MLST) clinical isolates of S. pneumoniae (n = 36) and S. pyogenes (n = 12) from the National Surveillance Program for ...

The objective of present investigation was to determine antimicrobial activity of Thymus vulgaris oil on some oral pathogens. Thymus vulgaris oil was prepared by hydrodistillation and tested against 30 clinical isolates of each of Streptococcus pyogenes, Streptococcus mutans, Candida albicans, Porphyromonas gingivalis, and Aggregatibacter actinomycetemcomitans, prepared from related oral infect...

The in vitro activities of ABT-773, erythromycin, clarithromycin, and azithromycin were compared. ABT-773 was the most active compound against macrolide-susceptible Streptococcus pneumoniae, Streptococcus pyogenes, Staphylococcus aureus, Staphylococcus epidermidis, Listeria monocytogenes, and Enterococcus spp. and multidrug-resistant Streptococcus pneumoniae. It also had good activity against g...

Introduction: The beta hemolytic Streptococci (SBH), particularly the group A (pyogenes) is the leading bacterial cause of sore throat that occurs primarily in the paediatric population. Objective: To evaluate the antimicrobial susceptibility of beta hemolytic Streptococcus from paediatric patients with pharyngitis, and infer the type of macrolide resistance mechanism. Material and methods: A t...
