Usually sheep blood agar, chocolate agar, and MacConkey agar plates are inoculated simultaneously from clinical specimens from areas of the human body where Haemophilus organisms may be isolated.Colonies of H.influenzae on chocolate agar appear translucent, tannish, moist, smooth, and convex, with a distinct "mousy, mouse nest," or "bleachlike" odor.
