Metastatic pyaemic abscesses occur MOST frequently as a complication of infection with which organism?
a. Bruceila abortus
b. Cory ne bacterium diphtheriae
c. Salmonella typhimurium
d. Staphylococcus aureus
e. Streptococcus viridans.
The correct answer is (d) Staphylococcus aureus.
Metastatic pyaemic abscesses are a complication of infection where bacteria enter the bloodstream and form abscesses in distant organs. Staphylococcus aureus is a common cause of this condition due to its ability to:
1. Invade the bloodstream
2. Form abscesses in various organs
3. Produce toxins that facilitate metastatic spread
Staphylococcus aureus is a virulent bacterium that can cause a range of infections, from skin and soft tissue infections to life-threatening conditions like endocarditis and sepsis.
While the other options can also cause infections, they are less commonly associated with metastatic pyaemic abscesses:
– Brucella abortus (a) typically causes brucellosis, a zoonotic disease with a focus on the reticuloendothelial system.
– Corynebacterium diphtheriae (b) is known for causing diphtheria, a respiratory infection.
– Salmonella typhimurium (c) is a common cause of gastroenteritis.
– Streptococcus viridans (e) is a group of streptococci commonly found in the oral cavity and gut, typically causing endocarditis or other infections in immunocompromised individuals.
