Host- an animal or plant on or in which a parasite or commensal oraganism lives.
Vector- an organism,typically a biting insect or tick, that transmits a disease or parasite from one animal or plant to another.
Cyst- non motile stage of protozoa surrounded by resistant wall or membrane.
Intermediate host- organism that harbors the larval or asexual stages of the parasites life cycle.
Definitive host- an organism that harbors the adult or sexual stages of the parasites life cycle
separate parasites from fecal debris and increase the chances of detecting parasitic organisms when these are in small numbers.
use solutions which have higher specific gravity than the organisms to be floated so that the organisms rise to the top and the debris sinks to the bottom.
use solutions of lower specific gravity than the parasitic organisms, thus concentrating the latter in the sediment.
- to differentiate cells for microscopic examination in pathological specimens,
- to detect parasites such as malaria within the blood.
- for assisting in the identification of obliterated bronchioles by highlighting their muscle coats
- to stain chromosomes
- often used to create a karyogram
- facilitates the differentiation of blood cell types
