In the medical setting, the most important groups are the alpha-hemolytic streptococci S. pneumoniae and Streptococcus viridans group, and the beta-hemolytic streptococci of Lancefield groups A and B (also known as âgroup A strepâ and âgroup B strepâ).
H. influenzae can be differentiated from most other species of Haemophilus by its specific requirement for both hemin and NAD for growth . H. haemolyticus is the only other species requiring both hemin and NAD for growth; however, this species differs from H. influenzae by producing beta-hemolysis (clear) on horse or rabbit blood. For patients with bacterial meningitis, H. influenzae must be considered as the presumptive causative agent as opposed to H. haemolyticus when both hemin and NAD factors are required for growth. To differentiate between the two species, hemolysis must be checked on horse or rabbit blood agar (see Section II.B., Haemophilus ID Quad plate section below).
