lives on the outside of its host; a flea is an example of an ectoparasite. Endoparasites, such as tapeworms, live within their host.
Which disease is transmitted by flea?
Flea-borne (murine) typhus, is a disease caused by a bacteria called Rickettsia typhi. Flea-borne typhus is spread to people through contact with infected fleas. Fleas become infected when they bite infected animals, such as rats, cats, or opossums.
How are Endoparasites transmitted?
Endoparasites are transmitted by
the fecal-oral route
, typically via contaminated food or water. Infection by Toxoplasma gondii is caused by ingestion of sporulated oocysts in cat feces or cyst-infected raw meat.
Can fleas live in human hair?
Fleas do not live on humans because they lack substantial hair like animals
, and it’s very difficult to reproduce without the protection of fur or feathers. One lab study observed that a flea would have to feed on a human for 12 straight hours to have the chance to lay viable eggs.
Do fleas carry Lyme disease?

through air, food, water, or from the bites of mosquitoes, flies, fleas, or lice.
Can fleas burrow under human skin?

What is the difference between ectoparasites and endoparasites?
Endoparasites live inside an organism, and
ectoparasites live on the surface of the host
.
What are the two main types of endoparasites?
Endoparasites are of two forms:
intercellular parasites and intracellular parasites
. Intercellular parasites are those that inhabit the spaces of the body of the host. Intercellular parasites are endoparasites that live within the cell of the host.
What is difference between parasite and pathogen?
