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.

The current standard for automated blood culture testing as recommended by the College of American Pathologists (CAP) is a five-day incubation period (CAP checklist, 2014); and even for the more fastidious so-called HACEK group of organisms (e.
Kingella kingae, a short Gram negative bacillus, is best known for being a constituent of the HACEK group of organisms; i.
1 Kingella kingae, and 1 Actinobacillus actinomycetemcomitans were identified among the HACEK group (Haemophilus, Actinobacillus, Cardiobacterium, Eikenella, Kingella.
Thus, the isolation of fastidious microorganisms including Abiotrophia (new genus Granulicatella) and the HACEK group, has improved dramatically, and organisms frequently missed with the use of earlier blood culture techniques are now recognized.
