Malaria revision

  • Clinical Tropical Medicine sessions started yesterday at the QEII Medical Centre with malaria 1 and 2
  • Self-assessment questions follow for those thinking about doing the FACTM part 1 exam this year
    • Here are some questions based on the first two Malaria modules.
    • Additional self-assessment exercises for prospective candidates on the ACTM website .

Problem 1

What parasitic infection is this and why?

(both results are from the same blood sample)

  • Likely non-falciparum malaria.
  • The HRP 2 P. falciparum band is absent on the rapid test.
  • A weak band is present against the P. vivax – P. ovale – P. malariae position.
  • There are no features in the thin film pointing to P. falciparum
  • The trophozoites could belong to one of several Plasmodium species

Problem 2

What infection is this and why?

(both views are from the same blood film)

  • Likely non-falciparum malaria.
  • A single, amoeboid Plasmodium trophozoite is present inside and RBC
  • The RBC is not deformed and has faint Schuffner’s dots
  • Lower panel shows a likely gametocyte which is not crescent-shaped
  • There are no features in the thin film pointing to P. falciparum
  • The trophozoites could belong to one of several Plasmodium species

Here’s the clinical parasitology mini-lecture you may have missed, now in its new, minimalist version.
