What are the diseases associated with the hacek group?
The HACEK group comprises commensal organisms of the human oropharynx. Although most notable for causing infective endocarditis, they are significant causes of other diseases including periodontitis, abscesses, and septic arthritis.
Where are HACEK organisms found?
HACEK organisms are typically oropharyngeal commensals and have long been recognized as a cause of infective endocarditis (IE). Eikenella and Cardiobacterium species have been recovered from the gastrointestinal tract and female genital tract.
What is the drug of choice against the hacek group?
Ceftriaxone (Rocephin)
Drug of choice for treatment of endocarditis due to HACEK organisms.
Are HACEK organisms culture negative?
These organisms can cause “culture negative endocarditis” meaning infection of the endocardium with vegetation formation despite blood cultures not showing evidence of bacteremia.
How do you identify HACEK organisms?
HACEK organisms are not readily identified on most automated bacterial identification systems, and most require either time-consuming biochemical profiling or genetic analysis, such as 16S rRNA gene sequencing, for definitive identification (8).
What is a HACEK mark?
háček in British English
(ˈhɑːtʃɛk ) noun. a diacritic mark (ˇ) placed over certain letters in order to modify their sounds, esp used in Slavonic languages to indicate various forms of palatal articulation, as in the affricate č and the fricative trill ř used in Czech. Word origin. from Czech.
What are the most common organisms that cause infective endocarditis?
Approximately 80% of infective endocarditis cases are caused by the bacteria streptococci and staphylococci. The third most common bacteria causing this disease is enterococci, and, like staphylococci, is commonly associated with healthcare-associated infective endocarditis.
How are HACEK organisms treated?
Ceftriaxone or ampicillin/sulbactam is the therapy of choice for patients with HACEK endocarditis. Fluoroquinolones may be considered as alternative therapy. Regardless of the agent chosen, treatment should last 4 to 6 weeks, depending upon the type of valve involved.
What antibiotics are used to treat endocarditis?
Treatment with aqueous penicillin or ceftriaxone is effective for most infections caused by streptococci. A combination of penicillin or ampicillin with gentamicin is appropriate for endocarditis caused by enterococci that are not highly resistant to penicillin.
What are the dots above letters called?
Diacritics, often loosely called `accents’, are the various little dots and squiggles which, in many languages, are written above, below or on top of certain letters of the alphabet to indicate something about their pronunciation.
What language uses Š?
It is used in Lakota, Cheyenne, and Cree (in dialects such as Moose Cree), Classical Malay (until end of 19th century) and some African languages such as Northern Sotho and Songhay.
What are 2 common bacterial causes of infective endocarditis?
Two kinds of bacteria cause most cases of bacterial endocarditis. These are staphylococci (staph) and streptococci (strep). You may be at increased risk for bacterial endocarditis if you have certain heart valve defects.
Which antibiotic is most commonly prescribed for infective endocarditis?
If this dose is missed, patients can receive antibiotics up to 2 hours after the procedure. The most commonly prescribed antibiotic is oral penicillin. People who are allergic to penicillin can be given cephalosporins, macrolides (different classes of antibiotics), or clindamycin.
Is HACEK normal flora?
Haemophilus species, Aggregatibacter species, Cardiobacterium Hominis, Eikenella Corrodens and Kingella species (HACEK) organisms are found as part of the normal human oral flora.
What bacteria causes endocarditis?
Acute bacterial endocarditis is usually caused by staphylococcus aureus bacteria and occasionally by the bacterial strains brucella and listeria. This form of infective endocarditis, compared to other forms, is more likely to affect normal heart valves.
What are the symptoms of bacterial endocarditis?
Common symptoms of endocarditis include:
- Aching joints and muscles.
- Chest pain when you breathe.
- Fatigue.
- Flu-like symptoms, such as fever and chills.
- Night sweats.
- Shortness of breath.
- Swelling in the feet, legs or belly.
- A new or changed whooshing sound in the heart (murmur)

Who is at risk of endocarditis?
Endocarditis occurs most often in adults over age 60. Artificial heart valves. Germs are more likely to attach to an artificial (prosthetic) heart valve than to a regular heart valve. Damaged heart valves.

What is this ô called?
circumflex accent
The circumflex accent marks the stressed vowel of a word in some languages: Portuguese â, ê, and ô are stressed “closed” vowels, opposed to their open counterparts á, é, and ó (see below).
