They undergo multiple divisions and develop into schizontss. By hitching a ride on another organism or even the wind these spores can travel. This is similar to sperm and eggs which are similar to human sex cells.

The life cycle of Plasmodium vivax is divided into. The sporozoites elongated and spindle-shaped become rounded inside the liver parenchymal cells. It causes malignant tertian or falciparum malaria.

Asexual cycle or Schizogony in man a. Sporozoites undergo a developmental phase inside the liver cells known as pre-erythrocytic schizogony. The human body is the primary host while the female Anopheles mosquito is the secondary or intermediate host.

Infection Schizogony is the process of asexual reproduction by which Plasmodium undergoes asexual multiplication in liver cells and RBCs of man. Mam-malian malarias are conﬁned to antelopes lemurs bats rodents and primates including humans and absent in felids canids equids or bovids for unknown reasons. And lizards in which part of its life cycle is spent.

Morphology life cycle pathogenesis and clinical disease. The gametocytes emerge from the infected blood cells becoming gametes. The thing that makes an organism unique is its way of life.

This malaria parasite called Plasmodium completes its life cycle in three stages namely Gametocytes which is the first stage then sporozoites which is the second stage and lastly merozoites which is the third and final stage. Exoerythrocytic stage in liver of man. The Plasmodium life cycle begins when parasites known as sporozoites produced in the insect vector enter the blood of the vertebrate host following a bite 33.
