What are the most likely pathogens involved in subacute bacterial endocarditis and what are the antibiotics of choice for its treatment?

The most common organism depends on the site of sur-gery. α-Hemolytic streptococci are the most common cause of endocarditis following dental procedures.

What are the most likely pathogens involved in subacute bacterial endocarditis and what are the antibiotics of choice for its treatment?

 

The most common organism depends on the site of sur-gery. α-Hemolytic streptococci are the most common cause of endocarditis following dental procedures. Other procedures around the oropharynx and airway, such as tonsillectomy and rigid bronchoscopy, also expose the patient to the same flora. The recommended antibiotic regi-men is outlined in Table 7.1.

Prophylaxis for genitourinary and gastrointestinal pro-cedures is directed against enterococci. The recommended antibiotic regimen is outlined in Table 7.2.

  


Patients at risk for endocarditis who are scheduled for cardiac surgery should receive prophylaxis against Staphylococcus aureus, staphylococcal coagulase-negative microbes, and diphtheroids. A first-generation cephalosporin is most often used; however, the choice must depend on the pathogen’s susceptibility pattern at each hospital. To reduce the risk of developing resistant organisms, patients should not be treated for more than 24 hours.
