Many protozoa, such as the agents of amoebic meningitis, use both pseudopodia and flagella. Some protozoa attach to the substrate or form cysts so they do not move around ( sessile ). Most sessile protozoa are able to move around at some stage in the life cycle, such as after cell division.

WebThe protozoa that are infectious to humans can be classified into four groups based on their mode of movement: Sarcodina – the ameba, e.g., Entamoeba Mastigophora – the flagellates, e.g., Giardia, Leishmania Ciliophora – the ciliates, e.g., Balantidium Sporozoa – organisms whose adult stage is not motile e.g., Plasmodium, Cryptosporidium Helminths WebParasitic protozoa feed in a variety of ways. Many live in the nutrient-rich medium of the body fluids--e.g., the blood or cells of their host. ... Carnivorous species exercise distinct selectivity. Most suctorians feed exclusively on particular ciliate taxa. They are selective feeders and usually do not capture flagellates, ... WebApproximately 10,000 of the described living species are parasitic. Protozoa infect most vertebrate and invertebrate species and have developed the capacity to adapt to living in most host organs. To date about 80 protozoan human pathogens have been described. how do you lose your hearing
