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 [...]
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 [...]
Giardia intestinalis inhabiting in the lumen of intestine is a cosmopolitan parasite causing chronic diarrhoea of acute type and leads to malabsorption in the intestine. This Giardia infection retards growth and development of children. The disease has been referred as a Giardiasis and it also has been indicated as a Zoonosis. Treatment of Giardiasis: i. Atebrin and acranil have [...]
