HACEK group

HACEK group

acronymic designation for a group of gram-negative bacteria that includes Haemophilus spp., Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae. Bacteria in this group have in common a culture requirement of an enhanced carbon dioxide atmosphere and ability to infect human heart valves.
