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 [...]
Each attack of fever shows three successive stages: i. Cold stage: At the beginning of malaria fever the patient suffers from a severe shaking chill. ii. Hot stage: As the chill subsides, the body temperature rises as high as 41° C or 106° F. iii. Sweating stage: D As the temperature lowers down, the patient sweats profusely. Malaria fever takes [...]
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 [...]
