Staphylococcus aureus is now the most common cause of infective endocarditis. Staphylococcus aureus is also particularly common in acute presentation and IVDUs coagulase-negative Staphylococci such as Staphylococcus epidermidis commonly colonize indwelling lines and are the most cause of endocarditis in patients following prosthetic valve surgery, usually …
• There are 2 category of people who are at high risk for bacterial endocarditis 1. People with damaged valves ( because damaged valves cause bacteria and fibrin to adhere) 2. IV drug abusers (because of constant bacteremia from bacteria entering the blood stream) •.
Native endocarditis of already damaged or previously abnormal valve have been observed to be caused most commonly (50% to 60%) by Streptococcus viridans, which is a common resident of normal oral cavity. Contrast to this, Staphylococcus aureus which is highly virulent organism and indistinguishably present all over the skin can infect impaired as ...
Infective endocarditis can be classified into Acute Endocarditis and Sub-Acute Endocarditis. In acute form infections are difficult to cure by prescribing antibiotics alone, thus require surgical intervention. While, sub-acute endocarditis is a chronic disease which develops slowly and by severity is less destructive so it can be treated by ...
In general, we can say that most common causes of infective endocarditis are Streptococcus viridans and Staphylococcus aureus. Depending on the presentation of the disease, medication or surgical procedure has to be followed. Advertisement.
Though development of the disease may be multifactorial, the main pathology behind the disease is formation of vegetations on previously damaged valve as seen in rheumatic heart disease or direct damage to cardiac tissue by a microorganism. This comprises of the thrombotic debris and the causative micro-organisms which usually belong ...
It can also be a contaminated needle which is shared by drug abusers commonly. Need not to say, trivial seeming breaks in the endothelial lining of hollow organs like gut, skin or oral cavity may also cause sepsis resulting in profound bacteremia.
Infective endocarditis (IE) is a rare, life-threatening disease that has long-lasting effects even among patients who survive and are cured. IE disproportionately affects those with underlying structural heart disease and is increasingly associated with healthcare contact, particularly in patients who have intravascular prosthetic material.
IE is a multisystem disease that can be fatal if left untreated and antimicrobial prophylaxis strategies for IE remain controversial. Introduction. Infective endocarditis (IE) is a multisystem disease that results from infection, usually bacterial, of the endocardial surface of the heart.
