Ampicillin/sulbactam is the agent-of-choice especially in the treatment of HACEK group
Favorable prognosis of patients with prosthetic valve endocarditis caused by gram-negative bacilli of the HACEK group

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.
i) Viridians streptococci, Streptococcus gallolyticus, HACEK group
, Staphylococcus aureus, or
Antibiotic treatment may be sufficient in native valve endocarditis and of late onset PVE due to sensitive organism like streptococci or HACEK group
in the absence of valvular complication.
Here we present a rare case of CIED associated endocarditis caused by Aggregatibacter actinomycetemcomitans, a member of the HACEK group.
After 10 days from the first admission, both the anaerobic and aerobic blood cultures on blood and chocolate agar plate with the presence of 5% carbon dioxide at 37[degrees]C grew Aggregatibacter actinomycetemcomitans, a member of the HACEK group of bacteria.
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.
