MM251020: P. malariae
Earlier in the week a couple of blood film images were shared as part of this week’s Morphology Monday case. On closer inspection the blood film revealed both trophozoites and schizonts of Plasmodium malariae.
MM250908: P. ovale
The overall findings were consistent with Plasmodium ovale infection, one of the less common species of malaria. It is typically associated with relapsing infections due to dormant liver hypnozoites and is often distinguished by oval-shaped infected red cells with fimbriated edges.
Not what it seems – a challenging case of malaria
While band forms are classically linked to P. malariae, morphological overlap can occur, and a confident diagnosis often requires correlation with clinical, geographic, and RDT findings.
The unseen enemy: Why today matters in the fight against malaria
Malaria disproportionately affects children under five and pregnant women, especially in sub-Saharan Africa.
