Describe the cycle of Golgi in the life history of Plasmodium Vivax ?

Explanation

It was first described by Camillo Golgi. Hence it also called Golgi cycle. This is intiated either by the cryptozoites of pre-erythrocytic cycle (or) the micro meta cryptozoites of exo-erythrocytic cycle. In the fresh R.B.C, these stages assumes spherical shape and transforms into trophozoite. It develops a small vacuole which gradually enlarges in size, pushes the cytoplasm and nucleus to the periphery. Now the plasmodium looks like a finger ring. Hence this stage is called signet ring stage soon it loses the vacuole, developes pseudopodea and becomes amoeboid stage. With the help of pseudopodium, it actively feeds on the content of the R.B.C and increase in size. As a result, the R.B.C grows almost double the size. This process is called hypertrophy. The malaria parasite digests the globin part of the ingested haemoglobin and converts the soluble haem into insoluble Haemozine. It is called malaria pigment. During this stage small red coloured dots appear in the cytoplasm of R.B.C known as "Schuffner.s dots.. Now the parasite loses the psedopodia and increase in size finally it occupies entire R.B.C and become schizont. It undergoes schizogony and produce 12-24 erythrocytic merozoites. They are arranged in the form of rose hence this stage is called rossette stage. Finally merozoites released along with .haemozoine into the blood.
