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 [...]
The following points highlight the four main parasitic adaptations of helminths. The adaptations are: 1. Morphological Adaptations 2. Physiological Adaptations 3. Life Cycle Adaptations 4. Immunological Adaptations. 1. Morphological Adaptations: The Helminths, though are of lower grade of organisms, show structural modifications or adaptations along two lines: (a) Degeneration or loss of organs or systems; (b) Attainment of new organs.
