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.

  • Fine ring form The small and delicate form of this species

    Fine ring form The small and delicate form of this species

  • Double chromatin dot form Two chromatin dots (sometimes known as "signet ring" form).

    Double chromatin dot form Two chromatin dots (sometimes known as "signet ring" form).

  • Accolé form: The arrowed form is closely associated with the red cell membrane

    Accolé form: The arrowed form is closely associated with the red cell membrane

  • Multiple parasites Two parasites within a single red cells (arrowed)

    Multiple parasites Two parasites within a single red cells (arrowed)

  • High parasitaemia Most of the typical early trophozoite P.falciparum forms are present
