Antiprotozoal drugs target infectious protozoans through mechanisms like antimetabolites such as atovaquone, proguanil, and artemisinins. These drugs are used to treat various protozoan infections including malaria, babesiosis, and toxoplasmosis. Artemisinin, a potent antimalarial compound, is deriv

Paramoecium caudatum is a typical ciliate protozoan characterized by the presence of cilia as a locomotor organelle, nuclear dimorphism, and a unique form of sexual reproduction called conjugation. Commonly found in freshwater habitats, this microscopic organism has a distinct structure with a pelli

Parasitic infections pose complex challenges to the immune system due to the diverse nature of parasites, including protozoans and helminths. Protozoan parasites move between arthropod vectors and mammalian hosts, requiring both humoral and cell-mediated immune responses. Meanwhile, helminths, as mu

Entamoeba Histolytica is a zoonotic protozoan parasite found in the digestive tract of various hosts. It mainly exists in two stages - Trophozoite and Cyst. Trophozoites are characterized by their size, clear ectoplasm, and movement via pseudopodia. Cysts are resistant structures with different cont

Entamoeba histolytica is a zoonotic protozoan parasite found in the digestive tracts of various hosts. It exists in trophozoite and cyst forms, with trophozoites containing erythrocytes and pseudopodia. The cyst stage is characterized by spherical masses discharged by trophozoites and containing chr

Paramecium, a widely studied protozoan organism, is found in various freshwater habitats. It exhibits unique characteristics such as locomotion through cilia, holozoic nutrition, and intracellular digestion. This microscopic organism reproduces both asexually and sexually, displaying a complex nucle
