Emergence of mefA and mefE genes in beta-haemolytic streptococci and pneumococci in France.
Sir, Since the early 1990s, most developed countries have experienced a rapid and substantial increase in erythromycin resistance among isolates of Streptococcus pyogenes and Streptococcus pneumoniae, probably related to the increased prescribing of this antibiotic or its novel semisynthetic derivatives. Until recently, the unique mechanism of macrolide resistance recognized in streptococci was...
متن کاملIncidence of mefA and mefE genes in viridans group streptococci.
Viridans group streptococci form the major part of the commensal flora of the human upper respiratory tract. However, these organisms are also the leading cause of infective endocarditis and an increasing source of bacteremia in neutropenic patients (1). Beta-lactam agents are the treatment of choice for these infections, but macrolides and related drugs are recommended for prophylaxis and alte...
متن کاملDistribution of subclasses mefA and mefE of the mefA gene among clinical isolates of macrolide-resistant (M-phenotype) Streptococcus pneumoniae, viridans group streptococci, and Streptococcus pyogenes.
The distribution of subclasses mefA and mefE of the mefA gene among 116 M-phenotype streptococci was as follows: pneumococci (38 strains had mefE and 4 mefA), viridans streptococci (49 mefE and 1 mefA), and Streptococcus pyogenes (24 mefA). Spain(9V)-3-14 and England(14)-9 clones of serotype 14 were dominant among pneumococci.
