Sample item

Which feature is typical of strongyloidiasis in an immunosuppressed host?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Hyperinfection with disseminated larvae

Strongyloides can autoinfect the host, and immunosuppression may cause hyperinfection with extensive gastrointestinal and pulmonary disease.

Option by option

  • A. Protected lifelong immunity after one infection

    Immunity does not reliably clear all larvae.

  • B. Meningitis from encapsulated yeast

    Encapsulated yeast describes Cryptococcus.

  • C. Primary infection only through mosquitoes

    Mosquitoes do not transmit Strongyloides.

  • D. Hyperinfection with disseminated larvae (correct)

    Correct: autoinfection enables severe hyperinfection.
