General description

Member of the genus Haemophilus require hemin (X factor) and/or nicotinamid-adenin-dinucleotid (V-factor). Together with the X factor (Cat. No. 77148) and the V factor (Cat. No. 89788) the need for either one or both factors provides the main means of differentiation of these organisms. Haemophilus species requiring both X and V factors exhibit growth only in the vicinity of the X +V factor discs.
