Evaluation of the Lyra Direct Strep Assay To Detect Group A Streptococcus and Group C and G Beta-Hemolytic Streptococcus from Pharyngeal Specimens.
The Lyra Direct strep assay was compared to culture for its ability to detect Streptococcus group A and β-hemolytic groups C/G using rapid antigen-negative pharyngeal specimens (n = 161). The Lyra assay correctly detected all β-hemolytic streptococci (group A, n = 19; group C/G, n = 5). In batch mode, the Lyra assay reduced intralaboratory turnaround time by 60% (18.1 h versus 45.0 h) but incre...
متن کاملIncidence and characterization of beta-hemolytic Streptococcus milleri and differentiation from S. pyogenes (group A), S. equisimilis (group C), and large-colony group G streptococci.
The biochemical characteristics of 172 clinical isolates of group A, C, F, or G or "nongroupable" beta-hemolytic streptococci were examined. Among these isolates, 91 were identified as beta-hemolytic strains of Streptococcus milleri. The remaining isolates included 20 Streptococcus pyogenes, 21 Streptococcus equisimilis, 37 large-colony group G streptococci, and 3 unidentified nongroupable isol...
متن کاملBeta-hemolytic streptococcus group A endocarditis: a rare clinical presentation.
A case report of an elderly gentleman is reported herein, who presented with one week history of fever, drowsiness and left lower limb weakness. Examination revealed left lower limb weakness with power of grade 3/5. His workup showed evidence of infection and multiple cerebral infarcts on the right side. Blood culture grew Streptococcus pyogens. Echocardiogram showed two vegetations on the aort...
متن کاملHigh-level aminoglycoside resistance in the beta-hemolytic group G Streptococcus isolate BM2721.
The beta-hemolytic group G Streptococcus clinical isolate BM2721 was resistant to high levels of aminoglycosides by synthesis of AAC(6')-APH(2"), APH(3')-III, and ANT(6) modifying enzymes. The corresponding genes were found to be adjacent as the result of a recombination event between Tn4001 and Tn5405, two transposons originating in staphylococci.
متن کاملGroup A Streptococcus pharyngitis and pharyngeal carriage: A meta-analysis.
OBJECTIVE Antibiotic treatment of Group A Streptococcus (GAS) pharyngitis is important in acute rheumatic fever (ARF) prevention, however clinical guidelines for prescription vary. GAS carriers with acute viral infections may receive antibiotics unnecessarily. This review assessed the prevalence of GAS pharyngitis and carriage in different settings. METHODS A random-effects meta-analysis was ...
