SBE prophylaxis is about preventing bacteremia from oral flora during invasive dental procedures, specifically targeting the organisms most likely to cause endocarditis from the mouth. Viridans group streptococci are the most common oral inhabitants that enter the bloodstream with dental manipulation and are the classic targets of prophylaxis, since they are the primary culprits in dental-origin infective endocarditis.

Enterococcus is more often linked to the GI and genitourinary tracts and nosocomial settings, not the typical dental source. Pseudomonas and Candida are not the usual culprits of dental-origin bacteremia that prophylaxis aims to prevent, as they are associated with different environments or systemic conditions rather than the oral flora implicated in endocarditis after dental procedures.

So, the organisms SBE prophylaxis is designed to protect against are viridans streptococci.
