[Evaluation of a selective medium for the isolation of Moraxella catarrhalis].
The recovery rate of Moraxella catarrhalis in a selective culture medium with acetazolamide and in a conventional blood-agar medium was compared from 1291 samples from the respiratory tract and conjunctivae of children and adults with respiratory and ocular symptomatology. M. catarrhalis was recovered in 215 samples on the acetazolamide medium, and only. 18 cases in the blood agar medium (p < 0.001). The highest recovery of M. catarrhalis was in samples with an accompanying flora, either pathogenic or commensal, such as pharyngeal and nasal exudates. The prevalence of M. catarrhalis in adults and children was 2% and 28%, respectively. We therefore, recommend the use of the acetazolamide medium for the recovery of M. catarrhalis in samples where M. catarrhalis is expected to be present with an accompanying flora.
