4.3.2 Haemophilus influenzae

Identification of Haemophilus species requires a combination of methods. Colonies on blood or chocolate agar may be presumptively identified by colony morphology. Haemophilus species produce colonies that are flat, convex and grey-white on blood agar. Following presumptive identification, further techniques, including MALDI-TOF or biochemical tests can be used to further identify the species.
