Comparisons of endogenous control genes in real-time polymerase chain reaction gene expression studies involving Moraxella catarrhalis are rare. This study shows that a combination of the iron sequestering gene copB and 16S rRNA genes would be useful for lineage 1 (16S rRNA type 1) isolates, but not lineage 2 (16S rRNA types 2 and 3) isolates.
