Match each patient presentation and history of infective endocarditis to the most likely causative organism.
- A 65-year-old man who recently underwent a cystoscopy for benign prostatic hyperplasia.Enterococcus faecalis
- A 72-year-old man who recently underwent a colonoscopy revealing a suspicious colonic mass.Streptococcus gallolyticus
- A 28-year-old man with a history of intravenous drug use presenting with a tricuspid valve vegetation.Staphylococcus aureus
- A 45-year-old woman with a history of mitral valve prolapse who recently had a dental extraction.Viridans group streptococci
- A 55-year-old man who had a prosthetic aortic valve placed 3 weeks ago.Staphylococcus epidermidis
Cevap
1 matches to Enterococcus faecalis (GU manipulation), 2 matches to Streptococcus gallolyticus (colon cancer), 3 matches to Staphylococcus aureus (IV drug use), 4 matches to Viridans streptococci (dental work), and 5 matches to Staphylococcus epidermidis (recent prosthetic valve).
The correct matches reflect the established epidemiological associations between specific patient risk factors and the organisms most likely to cause infective endocarditis in those clinical scenarios.
