Macrolide resistance in group A streptococci

Journal of Antimicrobial Chemotherapy, 2000
Two hundred and twenty one Streptococcus pyogenes isolates collected from throat swabs of untreated children with uncomplicated pharyngotonsillitis living in two centres situated in the north of Italy were tested to evaluate their macrolide resistance phenotype.

Erythromycin-Resistant Group A Streptococci

Archives of Pediatrics & Adolescent Medicine, 1981
Sir .—Subsequent to the article by Maruyama et al (Journal1979; 133:1143-1145), which reported resistance of group A streptococci to erythromycin, our group performed resistance studies to penicillin, erythromycin, and cephalosporin on 200 group A streptococci cultures. We found all to be sensitive to each antibiotic.

Resistance to Erythromycin in Group A Streptococci

New England Journal of Medicine, 1992
The use of erythromycin in Finland nearly tripled from 1979 to 1989. In 1988, we observed an unusually high frequency of resistance to erythromycin in group A streptococci in one geographic region. Because routine testing does not detect the sensitivity of these organisms to antibiotics, we initiated a national study to evaluate the extent of this ...

Enhancement of Mouse-virulence of Group A Streptococci

Nature, 1957
THE virulence of organisms can be enhanced by a variety of substances, mainly of carbohydrate nature (see review by Olitzki1). Current interest centres on mucin, which was found by Smith and his co-workers2–4 to owe its activity to the synergic action of three factors—viscosity, a particulate residue and a heparin.
