An improved antiserum agar method for detecting carriage of Haemophilus influenzae type b.
Enriched Columbia medium was tested against Levinthal medium for the isolation of Haemophilus influenzae type b. In both media, Haemophilus influenzae type b recovery and antigen-antibody precipitation halos were equivalent. Haemophilus influenzae type b colony size and iridescence were superior on enriched Columbia medium. Enriched Columbia medium is inexpensive, simply prepared and easily standardised.
