Question

What percent of Staphylococcus aureus infections are due to the patient's own flora?
A)10-20%
B)30-100%
C)40-50%
D)0%

Accepted Answer

Staphylococcus aureus is part of the normal human flora, which means it is commonly found on the skin and in the nasal passages of healthy individuals. Therefore, a large percentage of infections are due to the patient's own flora. The range is quite broad, from 30% to 100%, depending on the type of infection and the population being studied. This is why it is critical to practice good hygiene to prevent the spread of infections caused by S. aureus. Option A (10-20%) and C (40-50%) are not accurate ranges, and option D (0%) is incorrect.
