Clonal relatedness of erythromycin-resistant Streptococcus pyogenes isolates in Germany.
In a nationwide study in Germany, a total of 381 Streptococcus pyogenes were collected. Erythromycin A-resistant strains were characterized for the underlying resistance genotype, showing 55.6% had the efflux type mef(A), 31.5% had erm(A), and 13.0% had erm(B). A total of 23 different multilocus sequence types were observed.
متن کاملClonal differences among erythromycin-resistant Streptococcus pyogenes in Spain.
The aim of this study was to determine whether the high levels of erythromycin resistance in Streptococcus pyogenes found in Spain are due to the introduction and spread of one or more clones. Phenotypic and genotypic techniques were used to characterize all erythromycin-resistant S. pyogenes (ErR) isolated in Gipuzkoa, Spain, in the last 10 years and 128 ErR isolated in Vitoria and Madrid duri...
متن کاملStreptococcus pyogenes erythromycin resistance in Italy.
Letters importance of this symptomatic shedding in transmission among preschool children is well established (3); however, that of symptom-free shedding in adults is unknown. We report here that the rate of symptom-free STEC O157:H7 shedding is higher in adults 30 to 49 years of age than in others. STEC infections have been notifiable in Japan since August 1996. When STEC is found in the feces ...
متن کاملErythromycin resistance in Streptococcus pyogenes in Italy.
In a prospective study of acute pharyngitis in Italian children, 69 (38.3%) of 180 isolates of Streptococcus pyogenes were resistant to macrolides. S. pyogenes was eradicated in 12 (63.1%) of 19 patients with erythromycin-resistant S. pyogenes treated with clarithromycin and in 22 (88%) of 25 patients with erythromycin-susceptible strains. The constitutive-resistant phenotype was correlated wit...
متن کاملEmergence of erythromycin- and clindamycin-resistant Streptococcus pyogenes emm 90 strains in Hawaii.
We identified 12 erythromycin- and clindamycin-resistant emm 90 group A streptococcus (GAS) isolates during a retrospective invasive disease survey in Hawaii. A comparison with 20 type-matched isolates showed all resistant isolates to be emm 90.4b with the constitutive or inducible macrolide-lincosamide-streptogramin B resistance phenotype (cMLS(B) or iMLS(B)). All isolates had the same pulsed-...
