Introduction Parasitology 🪱
Terminology in Parasitology
Parasitology
- branch of science which deals with the study of the relationship between the parasite and host.
The term 'parasitology' is originated from Greek word- 'Para' means beside, 'sitos' means food and 'logus' means study
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
Specimens used in Parasitology 🧪
Urine 💧
Sputum
Liver
Liver aspirates
Duodenal aspirates
Bile
Corneal scrapings
👀Contact lens fluid
Tissue 🤧
Staining used in Parasitology
Trichrome stain (Wheatley trichrome stain)
for assisting in the identification of obliterated bronchioles by highlighting their muscle coats
Giemsa stain
to stain chromosomes
often used to create a karyogram
Wright's stain
facilitates the differentiation of blood cell types
Romanowsky stain
to differentiate cells for microscopic examination in pathological specimens,
to detect parasites such as malaria within the blood.
Techniques used in Parasitology
Flotation Technique
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.
Sedimentation Technique
use solutions of lower specific gravity than the parasitic organisms, thus concentrating the latter in the sediment.
Concentration technique
separate parasites from fecal debris and increase the chances of detecting parasitic organisms when these are in small numbers.
