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 [...]
Difference between Entamoeba histolytica and Entamoeba coli: Difference # E. histolytica: A. Trophozoite stage: (i) Fairly abundant in amoebic dysentery stools. (ii) The size varies from 10-30µ (iii) The outline shows finger like pseudopodia. (iv) Actively motile in nature. (v) Cytoplasm: Ectoplasm—prominent; Endoplasm—finely granular with ingested RBCs Vacuoles—scanty, spherical and defined. Nucleus: Nuclear membrane uniformly stained with chromatin; karyosome is [...]
