Subjects with higher alcohol consumption had certain genera that were enriched, including Actinomyces, Leptotrichia, Cardiobacterium
, and Neisseria; some of these genera contain oral pathogens, and Neisseria can synthesize alcetaldehyde from ethanol.
The guts of abalone weaned onto kelp were dominated by anaerobic Clostridium species, whereas a variety of bacterial genera from Proteobacteria (Stenoxybacter and Cardiobacterium
), Actinobacteria (Micrococcus and Corynebacterium), and Flavobacteriia (Haloanella), were prevalent in abalone weaned onto S34 (Table 3).
(40) used sequencing of the bacterial 16S rRNA gene to evaluate oral microbiota in children with and without black stain and found that Actinomyces, Cardiobacterium
, Haemophilus, Corynebacterium, Tannerella and Treponema were more abundant in plaque samples of children with black stain, while Saba et al.

Aggregatibacter aphrophilus (formerly Haemophilus aphrophilus) is an aerobic gram-negative coccobacillus that belongs to the HACEK (Haemophilus aphrophilus/paraphrophilus, Actino bacillus actinomycetem comitans, Cardiobacterium
hominis, Eikenella corrodens and Kingella spp.) group.
(2) Rare causes of infective endocarditis are Gram-negative organisms, including the HACEK group: Haemophilus species, Aggregatibacter (previously Actinobacillus) species, Cardiobacterium
hominus, Eikenella corrodens, and Kingella species.

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.g., Haemophilus, Aggregatibacter, Cardiobacterium
, Eikenella, Kingella) and Brucella spp., incubation beyond the five-day period is seldom required.
Menos del 2% de las endocarditis infecciosas son causadas por germenes gram negativos no HACEK (Hemophilus, Actinobacillus, Cardiobacterium
, Eikenella, and Kingella), incluyendo Pseudomonas aeruginosa (2).
