P.vivax gallery of late trophozoites


Summary There is no absolutely clear point at which early trophozoites of P.vivax become late trophozoites as it is simply a process of continuous development. However, the transition to an amoeboid parasite form where the original ring structure can no longer be seen will certainly place the parasites at this stage.

  • Very early double dot form Very early red cell changes with fine dots visible

    Very early double dot form Very early red cell changes with fine dots visible

  • Early ring form Dots are more visible and the red cell begins to show distortion.

    Early ring form Dots are more visible and the red cell begins to show distortion.

  • Early ring form The ring has thickened with established dots and altered red cell size

  • Intermediate ring Amoeboid parasite within an enlarged distorted red cell with marked dots
