Case #173 – February, 2006

A 29-year-old missionary lived in Gabon and Cameroon for one year. Eight months into her stay, she went to a medical clinic with complaints of headache, fever, chills, and some diarrhea. She reported to the physician that she did not adhere consistently to her malaria prophylaxis regime. The physician ordered a blood film examination; thick and thin blood films were made and stained with Wright’s. Figures A-D show objects that were seen on the thin blood film. What is your diagnosis? Based on what criteria? Would you recommend any laboratory confirmatory test to make the diagnosis specific?
