The prevalence of M. catarrhalis colonization depends on age. About 1 to 5% of healthy adults have upper respiratory tract colonization. Nasopharyngeal colonization with M. catarrhalis is common throughout infancy, may be increased during winter months, and is a risk factor for acute otitis media; early colonization is a risk factor for recurrent otitis media.

To test this, we constructed a catalase mutant in the M. catarrhalis 7169 background (Mcat7169ΔkatASpec1) and assessed its protective capacity in the transwell assay. The mutant had a phenotype similar to the wild-type demonstrating that catalase production by M. catarrhalis was not essential for protection. To test this, we constructed a catalase mutant in the M. catarrhalis 7169 background (Mcat7169ΔkatASpec1) and assessed its protective capacity in the transwell assay.
