Multicenter study of the mechanisms of resistance and clonal relationships of Streptococcus agalactiae isolates resistant to macrolides, lincosamides, and ketolides in Spain.

چکیده
Macrolide, lincosamide, and ketolide mechanisms of resistance and clonal relationships were characterized in a collection of 79 resistant group B streptococcus isolates obtained from neonates or pregnant women. The erm(B), erm(TR), and mef(A) genes were present in 62%, 30.4%, and 3.8% of the isolates, respectively. There was considerable clonal diversity among them.

Macrolide and tetracycline resistance and molecular relationships of clinical strains of Streptococcus agalactiae.
Mechanisms for tetracycline and macrolide resistance in 54 isolates of erythromycin-resistant Streptococcus agalactiae were analyzed by PCR. The erm(B), erm(A), and mef(A) genes, either alone or in combination, were detected in all the erythromycin-resistant isolates. The tet(M) and tet(O) genes were responsible for tetracycline resistance. Random amplification of polymorphic DNA indicated diff...
متن کاملFirst clinical isolate in Europe of clindamycin-resistant group B Streptococcus mediated by the lnu(B) gene.
We characterize the mechanisms implicated in an unusual phenotype of resistance to macrolides-lincosamides (no halos of inhibition around clindamycin and lincomycin discs, and a 15 mm halo around erythromycin disc) in a Streptococcus agalactiae isolate recovered in Spain. The presence of macrolide or lincosamide resistance genes [erm(A), erm(B), erm(C), erm(T), mef(A), mrs(A), lnu(A), lnu(B), l...
متن کامل[Phenotypes and mechanisms of resistance to macrolides and lincosamides in Streptococcus agalactiae isolates with clinical significance in an eight-year period (2002-2010)].
INTRODUCTION Streptococcus agalactiae is the most prevalent agent of invasive disease in the newborn (sepsis, pneumonia, and meningitis), as well as an important cause of puerperal fever, urinary tract infection and surgical site infection. The aim of our study was to know the evolution of macrolide and lincosamide resistance in this microorganism. METHODS Resistance phenotypes were establish...

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-...
متن کاملPneumococcal resistance to macrolides, lincosamides, ketolides, and streptogramin B agents: molecular mechanisms and resistance phenotypes.
The macrolides, lincosamides, ketolides, and streptogramin B agents (the MLKS(B) antimicrobial agents) have related chemical structures and share similar molecular targets on the 50S ribosomal subunit of Streptococcus pneumoniae. Mutations in rRNA or ribosomal proteins generate a variety of resistance phenotypes. The M phenotype of S. pneumoniae, which predominates in North America, affords low...
