Antibiotic treatment lowers the risk of embolic complications in people with infective endocarditis. [ 11 ] In acute endocarditis, due to the fulminant inflammation, empirical antibiotic therapy is started immediately after the blood has been drawn for culture to clarify the bacterial organisms responsible for the infection.
The usefulness of antibiotics following dental procedures has changed over time. [7] Prevention is recommended in patients at high risk. [3] Treatment is generally with intravenous antibiotics. [3] The choice of antibiotics is based on the blood cultures. [3] Occasionally heart surgery is required.
The standard treatment is with a minimum of four weeks of high-dose intravenous penicillin with an aminoglycoside such as gentamicin. The use of high-dose antibiotics is largely based upon animal models. [2] Leo Loewe of Brooklyn Jewish Hospital was the first to successfully treat subacute bacterial endocarditis with penicillin. Loewe reported ...
The treatment of choice for HACEK organisms in endocarditis is the third-generation cephalosporin and β-Lactam antibiotic ceftriaxone. Ampicillin (a penicillin), combined with low-dose gentamicin (an aminoglycoside) is another therapeutic option. [7]
Dental antibiotic prophylaxis is the administration of antibiotics to a dental patient for prevention of harmful consequences of bacteremia, that may be caused by invasion of the oral flora into an injured gingival or peri-apical vessel during dental treatment.
Ceftriaxone, sold under the brand name Rocephin, is a third-generation cephalosporin antibiotic used for the treatment of a number of bacterial infections. [4] These include middle ear infections, endocarditis, meningitis, pneumonia, bone and joint infections, intra-abdominal infections, skin infections, urinary tract infections, gonorrhea, and pelvic inflammatory disease.

Current guidelines recommend daptomycin for VISA bloodstream infections and endocarditis. [4] Oxazolidinones such as linezolid became available in the 1990s and are comparable to vancomycin in effectiveness against MRSA. Linezolid resistance in S. aureus was reported in 2001, [101] but infection rates have been at consistently low levels.
Like other Rothia infections reported in the literature, once the cause of infection was identified, this responded fully to treatment with antibiotics. Rothia infections may be treated with penicillins, erythromycin, cefazolin, rifampin, aminoglycoside, tetracycline, chloramphenicol, and trimethoprim-sulfamethoxazole. [3]
