Abstract

The lack of selectivity of chocolated blood agar (CBA), routinely used forthe isolation of Haemophilus influenzae, may lead to masking of the growthof H, influenzae due to overgrowth of competing flora. Bacitracin can be used as a selective agent, either incorporated into the medium or applied tothe medium in a filter paper. However, neither method has been evaluated or compared in a large study. Sputum samples (1990) were examined in four laboratories and the isolation rates of R; influenzae on chocolated blood agar with bacitracin added to the medium (BCA) and chocolated blood agar (CBA)with a bacitracin disk were compared. A plain blood agar plate was also inoculated to facilitate the isolation of Streptococcus pneumoniae so that ifs effects on the isolation of H. influenzae could be assessed. No significant difference was found between the isolation rates of H, influenzae on BCAand CBA with a bacitracin disk, although competing flora was greatly reduced and quantity of growth of H, influenzae increased on BCA, The presence of S, pneumoniae did not affect the isolation of H. influenzae in this study.
