In this article we will discuss about the histology of malarial parasite. The malarial parasites belonging to the Genus, Plasmodium, possess a life cycle which shows an alternation of generation accompanied by an alternation of host. Schizogony of malarial parasite (asexual cycle) occurs in the red blood cells and also endothelial cells of inner organs in vertebrate host, while the [...]
Comparative account of four species of human infecting malarial parasite: 1. P. Vivax: i. Geographical distribution: In tropical, subtropical and warmer temperate regions. ii. Duration of pre-erythrocytic schizogony: 10-14 days iii. No. of crypto- zoites formed per schizont: 10,000-12,000 (approx.) iv. Incubation period: 14 days v. Duration of erythrocytic schizogony: 2 days vi. Form in peripheral blood during erythrocytic schizogony: [...]
In this article we will discuss about the life cycle of trypanosoma gambiense. Trypanosoma gambiense is digenetic; i.e., it completes its life cycle in two hosts. The primary or definitive host is man. The mammals, like pigs, buffaloes, antelopes often act as reservoir hosts harbouring the parasite. The intermediate host is blood sucking insect called tsetse fly (Glossina palpalis). Life [...]
