By way of example, a parasite that reproduces in an intermediate host may require, as part of their life cycle, that the intermediate host be eaten by a predator at a higher trophic level, and some parasites are capable of altering the behavior of the intermediate host to make such predation more likely; [1] [2] a mechanism that has been called ...

Human parasites are divided into endoparasites, which cause infection inside the body, and ectoparasites, which cause infection superficially within the skin. The cysts and eggs of endoparasites may be found in feces , which aids in the detection of the parasite in the human host while also providing the means for the parasitic species to exit ...
The malaria parasite modifies the skin odour of its human hosts, increasing their attractiveness to mosquitoes and hence improving the chance for the parasite to be transmitted. [36] The spider Cyclosa argenteoalba often have parasitoid wasp larvae attached to them which alter their web-building behavior.
The parasite is known to reproduce sexually only in the cat family. [9] However, it can infect most types of warm-blooded animals, including humans. [9] Diagnosis is typically by testing blood for antibodies or by testing the amniotic fluid in a pregnant patient for the parasite's DNA. [4] Prevention is by properly preparing and cooking food.

Pathogen avoidance, also referred to as, parasite avoidance or pathogen disgust, refers to the theory that the disgust response, in humans, is an adaptive system that guides behavior to avoid infection caused by parasites such as viruses, bacteria, fungi, protozoa, helminth worms, arthropods and social parasites.
