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...
Background: Recently, many cases diagnosed as pediatric autoimmune neuropsy-chiatric disorders associated with group A beta hemolytic streptococcus infection (PANDAS) due to production of autoimmune antibodies. Object of this study was comparison the titer of antibodies against group A beta hemolytic streptococcus (ASOT, Anti-DNase B, and Anti streptokinase) between children with movement...
Streptococcus dysgalactiae is classified by a combination of phenotypic and genotypic characteristics into Lancefield group C alpha-hemolytic Streptococcus dysgalactiae subsp. dysgalactiae and Lancefield group C, group G, and group L beta-hemolytic Streptococcus dysgalactiae subsp. equisimilis. In this study, we report the isolation of a catalase-negative, alpha-hemolytic, optochin- and bacitra...
A test is described that could replace bacitracin susceptibility for presumptive identification of group A streptococci as well as 6.5% NaCl agar tolerance for presumptive identification of enterococcal streptococci. The L-pyrrolidonyl-beta-naphthylamide test, based on hydrolysis of pyrrolidonyl-beta-naphthylamide, was used in conjunction with the CAMP and bile-esculin tests to presumptively id...
The aim of this study was to investigate antimicrobial susceptibilities and macrolide resistance mechanisms of beta-hemolytic viridans group streptococci (VGS) in a tertiary Korean hospital. Minimum inhibitory concentrations (MICs) of seven antimicrobials were determined for 103 beta-hemolytic VGS isolated from various specimens. The macrolide resistance mechanisms of erythromycin-resistant iso...
