Species belonging to this group include several Haemophilus species, Aggregatibacter (formerly Actinobacillus) species, Cardio-bacterium hominis, Eikenella corrodens, and Kingella kingae. HACEK bacteria normally reside in the oral cavity and have been associated with local infections in the mouth. They are also known to cause severe systemic infections—most often bacterial endocarditis, which can develop on either native or prosthetic valves (Chap. 155).
