In this article we will discuss about:- 1. Systematic Position and Distribution of Trypanosoma 2. Polymorphic Forms of Trypanosomes 3. Pathogenic and Non-Pathogenic. The family of Trypanosomidae is the important groups among the Haemoflagellates. Members of this family, the Trypanosomes, are all parasitic and were originally parasites of the digestive canal of insects. Now, many are found in the blood [...]
A comparison of the course of natural infection of P.vivax and P. falciparum in man: Comparison # P. Vivax: 1. Pre-erythrocytic schizogony: It consists of one cycle, lasts 7-8 days. Number of merozoites produced by each schizont is about 12,000. 2. Erythrocytic schizogony: Duration of erythrocytic schizogony is about 48 hours. Appearance of parasites in the peripheral blood on 12th [...]
Parasitic protozoa are classified mainly into four groups. They are: (a) Rhizopoda (Plasmodroma): The organisms of this group move by producing pseudopodia. They multiply by binary fission and form cysts, as in E. histolytica. (b) Mastigophora: The organisms move by means of flagella, binary fission takes place by longitudinal division e.g., Trypanosoma, Leptomonad etc. (c) Sporozoa: They move by amoeboid [...]
