Streptococcal infection tends to be more chronic though the average incubation period is 1 to 2 weeks. Endocarditis is a rare and potentially fatal infection of the inner lining of the heart the endocardium. Cutibacterium acnes deserves special consideration however as some strains of this species may require prolonged blood-culture incubation.

PubMed PubMed Central Google Scholar. 64 A longer incubation period between the invasive procedure and the onset of symptoms significantly lessens the likelihood that the procedure was the proximate cause of the endocarditis. The incubation period of subacute bacterial endocarditis.

Endocarditis is a disease characterised by inflammation of the endocardium typically affecting the heart valves and usually caused by infection and can be acute subacute or chronic most commonly affecting the aortic valve previously mitral valve most cases of fulminant endocarditis are caused by S.

Usually involving Staphylococcus bacteria short incubation endocarditis causes much more serious symptoms.

Yale J Biol Med 1977. Infective endocarditis IE arises when an adherent platelet-fibrin nidus becomes secondarily infected and produces vegetations which in turn may directly damage the endocardial tissue andor valves. When bacteria are virulent or bacterial exposure is massive ABE can affect normal valves.
