characteristics of protozoa pdf

Giardia 2. List the distinguishing characteristics of the two classes of parasitic helminths, and give an example of each. In the presence of medium-chain saturated FA (particularly C10:0 and C12:0), no ciliate protozoa (99.8%Entodinium spp.) Components of protozoa … Protozoa are unicellular eukaryotic microorganisms lacking a cell wall and belonging to the Kingdom Protista. Higher Microorganisms: Fungi, Protozoa, Algae (Eucaryotic cells) (Eucaryotic (Eukarya domain) = "true" nucleus) Lower Microorganisms: Bacteria (Procaryotic cells) (Bacterial domain) (A-4) Characteristics of structure and function exhibited by Eucaryotic as compared to Procaryotic cells. Trichonympha 4. These PAMPs bind to pattern-recognition receptors or PRRs on a variety of defense cells of the body and triggers innate immune defenses such as inflammation, fever, and phagocytosis.

These unique molecules are called pathogen-associated molecular patterns or PAMPs. Protozoa do not have a cell wall and therefore can have a variety of shapes. Some malaria parasite species also produce hypnozoites in the liver that remain dormant for extended periods, causing relapses weeks or months later. Components of protozoa that function as PAMPs include GPI-anchored proteins (GPI = Glycosylphosphatidylinositol) and mannose-rich glycans (short carbohydrate chains with the sugar mannose or fructose as the terminal sugar) that function as PAMPs. Protozoa Sarcomastig-ophora further divided into Sarcodina-- - move by pseudopodia Entamoeba E. histolytica Mastigophora move by flagella Giardia G. lamblia Apicomplexa no organelle of locomotion Plasmodium P. falciparum, P. vivax, P. malariae, P. ovale Ciliophora move by cillia Balantidium B. coli Microspora Spore-forming Enterocyto-zoa These mannose-rich glycans are common in microbial glycoproteins and glycolipids but rare in those of humans. Some protozoa can also reproduce sexually. Life Saving College Of Nursing M. Farooq Marwat RN, Dip. They exist as free-living organisms or as parasites.
