What are endemic parasites?
Endemic parasites are abundant in nature [1,2]. Such infections are often characterized by relatively low virulence, persistence in the host population and an extended evolutionary association between the parasite and its host [3,4].
How do nematodes defend themselves?
Upon nematode detection, receptor-like kinases activate immune signaling pathways, giving rise to a variety of chemical defenses [47]. A common host defense is the programmed cell death of tissues surrounding the site of infection, preventing the spread of invading pathogens [48].
What is the difference between mutualism commensalism and parasitism?
Mutualism is where both organisms benefit, commensalism is where one benefits but the other organism isn’t harmed, and lastly, parasitism is where one organism benefits and the other is harmed. The various species found within a single ecosystem can relate to each other in a variety of ways. The terms mutualism, commensalism, parasitism
What is an example of parasitism in humans?
Parasitism. Frequently the parasite actively lives on the body of the host, consuming nutrients from its blood or other parts of its body. Common examples of parasites include fleas, ticks, and tapeworms. Ticks and fleas live on the body of their hosts for a while, sucking their blood for nutrients.
Why do parasites have such a large reproductive potential?
They have a huge reproductive potential and release lots of eggs because the chances of the parasite finding another host is very small and many eggs will die. Mutualism is another type of relationship between two species, where both species benefit.
Why do parasites not kill the host?
Parasites do not usually kill the host because this would cut off their food supply. Parasites are adapted so that they receive maximum benefit from the host but do not kill them.
