Subacute bacterial endocarditis, abbreviated SBE, is a type of endocarditis (more specifically, infective endocarditis). [5] Subacute bacterial endocarditis can be considered a form of type III hypersensitivity .
Infective endocarditis is divided into the three categories of acute, subacute, and chronic based on the duration of symptoms. [11] Acute infective endocarditis refers to the presence of signs and symptoms of infective endocarditis that are present for days up to six weeks. [11]
Endocarditis is characterized by lesions, known as vegetations, which are masses of platelets, fibrin, microcolonies of microorganisms, and scant inflammatory cells. [1] In the subacute form of infective endocarditis, a vegetation may also include a center of granulomatous tissue, which may fibrose or calcify. [2]
The nodes are commonly indicative of subacute bacterial endocarditis. [4] 10–25% of endocarditis patients will have Osler's nodes. [5] Other signs of endocarditis include Roth's spots and Janeway lesions. The latter, which also occur on the palms and soles, can be differentiated from Osler's nodes because they are non-tender.

Splinter hemorrhages (or haemorrhages) are tiny blood clots that tend to run vertically under the nails.Splinter hemorrhages are not specific to any particular condition, and can be associated with subacute infective endocarditis, scleroderma, trichinosis, systemic lupus erythematosus (SLE), rheumatoid arthritis, psoriatic nails, [1] antiphospholipid syndrome, [2]: 659 haematological ...
S. sanguinis may gain entrance to the bloodstream when opportunity presents (dental cleanings and surgeries) and colonize the heart valves, particularly the mitral and aortic valves, where it is the most common cause of subacute bacterial endocarditis. For this reason, oral surgeons often prescribe a short course of antibiotics to be taken a ...
If they are introduced into the bloodstream, they have the potential of causing endocarditis, in particular in individuals with damaged heart valves. They are the most common causes of subacute bacterial endocarditis. Viridans streptococci are identified in cases of neonatal infections. [6]
The HACEK organisms are a group of fastidious Gram-negative bacteria that are an unusual cause of infective endocarditis, which is an inflammation of the heart due to bacterial infection. [1] HACEK is an abbreviation of the initials of the genera of this group of bacteria: Haemophilus , Aggregatibacter (previously Actinobacillus ...
