Genetic and phenotypic characterization of resistance to macrolides in Streptococcus pyogenes from Argentina.

Trends in Macrolide Resistance for Streptococcus pyogenes, Streptococcus agalactiae and Streptococcus pneumoniae and its Association with Social Clustering in Argentina

The aim of this work was to study and compare macrolide resistance patterns among Streptococcus pneumoniae, Streptococcus agalactiae and Streptococcus pyogenes, to describe the phenotypes of macrolide-lincosamide resistance and to further investigate associations between macrolide resistance and social clustering. Susceptibility data were obtained from 4 clinical microbiology laboratories in Ba...

Antibiotic susceptibility of Streptococcus pyogenes isolated from throat cultures of healthy children aged between 5-15 years

Streptococcus pyogenes is one of the most important causes of bacterial pharyngitis. Asymptomatic carriage of this organism especially among schoolchildren is a common issue. Study of the prevalence and antimicrobial susceptibility pattern of the flora strains, as clinical indicators, are useful for treatment of streptococcal infections. The aim of this study was to determine the prevalence and...

Low macrolide resistance in Streptococcus pyogenes in Southern Argentina.

Throat Carriage Rate and Antimicrobial Resistance of Streptococcus pyogenes In Rural Children in Argentina

OBJECTIVES The aim of this study was to determine the prevalence of asymptomatic carriers of group A β-hemolytic streptococci (GAS) in children living in a rural community and to investigate the association between episodes of acute pharyngitis and carrier status. METHODS Throat swabs were collected from September to November 2013 among children 5-13 years of age from a rural community (Maria...

Streptococcus pyogenes strains associated with invasive and non-invasive infections present possible links with emm types and superantigens

Objective(s): Streptococcus pyogenes, a notorious human pathogen is responsible to cause a wide range of infections varies from superficial common clinical illness to severe and life threatening infections. To our knowledge this is the first report exploring the emm types and superantigen/exotoxin gene profile of S. pyogenes from Pakistan. Materials a...
