Which infection is a typical opportunistic infection in a patient with AIDS?
Correct answer: B. Pneumocystis pneumonia
- A. Typhoid fever
- B. Pneumocystis pneumonia
- C. Malaria
- D. Cholera
Explanation
Pneumocystis jirovecii causes pneumonia almost only in people whose cell mediated immunity has failed, so it is one of the defining opportunistic infections of AIDS, along with tuberculosis, candidiasis and Kaposi's sarcoma. Typhoid, malaria and cholera are common infections in Pakistan that attack healthy people just as readily, so their presence says nothing about immune status.
