Abstract

Erm(A) is rarely reported as erythromycin resistance determinant in pneumococci. One invasive erm(A) isolate was initially tested intermediate erythromycin resistant using E-test. However, upon re-testing it was resistant, thus close to the breakpoint value. This may be a reason why erm(A) only rarely is reported to cause resistance in pneumococci.

Part of this study was presented at the Sixth Pneumococcal Congress 2005, Braunsweig, Germany. At Statens Serum Institute we thank Kirsten Burmeister and Frank Hansen for excellent technical assistance. We also acknowledge the use of the pneumococcal MLST database, which is located at Imperial College London and is funded by the Wellcome Trust.
