title: Clear broth and plate media for culture of Haemophilus ducreyi.
abstract: Using catalase as a source of heme, we have developed both clear plate and broth media for the growth of Haemophilus ducreyi, the causative agent of chancroid. In the broth medium, the growth phase of the organism can be monitored and the organisms achieve a cell density of > 10(8) CFU/ml.
