<span style="font-size:95%">At the very earliest point of growth, the malarial parasites may be difficult to distinguish from other early trophozoites. However, in this species a range of maturing forms are generally present and later forms begin to aquire characteristic features of the species - the trophozoites become larger and acquire thisckened and more irregular features. At the same time the red cells begin to enlarge and become less regular with the appearance of typical Schuffner's dots in the red cell cytoplasm.

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.

  • Developing late trophozoite The ring form is lost, the parasite is very irregular

    Developing late trophozoite The ring form is lost, the parasite is very irregular

  • Late trophozoite Note the solid parasite and the red cell begins to show distortion.

    Late trophozoite Note the solid parasite and the red cell begins to show distortion.

  • Late trophozoite Similar to the previous example, the ring structure is entirely lost

    Late trophozoite Similar to the previous example, the ring structure is entirely lost

  • Classical amoeboid form note also the very enlarged distorted red cell

    Classical amoeboid form note also the very enlarged distorted red cell
