Identify the correct pair representing the causative agent of typhoid fever and the confirmatory test for typhoid.

Options

  1. APlasmodium vivax / UTI test
  2. BStreptococcus pneumoniae / Widal test
  3. CSalmonella typhi / Anthrone test
  4. DSalmonella typhi / Widal test

Correct answer

D. Salmonella typhi / Widal test

Step-by-step solution

Salmonella typhi, the causative agent of typhoid fever, is approximately 50,000 years old. Assays that identify Salmonella antibodies or antigens support the diagnosis of typhoid fever, but these results should be confirmed with cultures or DNA evidence. The Widal test has been the anchor for diagnosis of typhoid fever for decades. It is used to quantify agglutinating antibodies against H and O antigens of S. typhi.
