P.falciparum gallery of late trophozoites


Summary At this stage we look for rings that are slightly thicker though still small with typical ring form, the red cells tend to become crenated and pale, losing central pallor as the parasites mature. Typical accolé forms, double chromatin dot forms, and multiple parasites within infected red cells are still present.

  • Late rings Two cells both with typical dots: multiply infected and double dot forms

    Late rings Two cells both with typical dots: multiply infected and double dot forms

  • Double chromatin dot form also Maurers dost and clefts, slight crenation and lost pallor

    Double chromatin dot form also Maurers dost and clefts, slight crenation and lost pallor

  • Accolé form: closely associated with the red cell membrane, scanty mauers dots

    Accolé form: closely associated with the red cell membrane, scanty mauers dots

  • Accolé form A nice typical form with scanty well-formed Maurers dots

    Accolé form A nice typical form with scanty well-formed Maurers dots

  • Small thick forms the red cell crenation is well demonstrated with scanty dots

    Small thick forms the red cell crenation is well demonstrated with scanty dots
