A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite lives on or in the body of the host. A few examples of parasites are tapeworms, fleas, and barnacles.
Examples of parasitic diseases that can be bloodborne include African trypanosomiasis, babesiosis, Chagas disease, leishmaniasis, malaria, and toxoplasmosis. In nature, many bloodborne parasites are spread by insects (vectors), so they are also referred to as vector-borne diseases.
Examples of parasitism are the helminths (worms) in the intestines of the host, lice (Pediculus humanus capitis) in human head, Plasmodium species transmitted by anopheline mosquito and causing malaria in humans.
Parasitism is a nonmutual relationship between two organisms in which one benefits at the expense of the other. There are two types of parasites affecting living organisms: ectoparasites (living on the surface of host) and endoparasites (living in the body of host).
Parasites may be grouped according to where they live. Ectoparasites, such as fleas and ticks, live on the surface of a host. Endoparasites, such as intestinal worms and protozoa in blood, live inside a host's body. Mesoparasites, such as some copepods, enter the opening of a host body and partially embed themselves.
Parasitism Examples
Your mind might jump to what we more commonly think of as a parasite like tapeworms or fleas. These are great examples because in both cases, the parasite benefits while the other organism is harmed.
Giardia is arguably the most common parasite infection of humans worldwide, and the second most common in the United States after pin-worm. 8,9. Between 1992 and 1997, the Centers for Disease Control and Prevention (CDC) estimated that more than 2.5 million cases of giardiasis occur annually. 10.
Lesson Summary
Ectoparasites (like mosquitos, ticks, and head lice) live on the skin of the host in an area where they can easily feed off the blood of the host. Endoparasites (like tape worms and roundworms) live inside the body of the host and benefit from the nutrients found within their digestive tracts.
There are four main symbiotic relationships: mutualism, commensalism, parasitism, and competition.
Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed.
Thus, the correct answer is option 'Birds and rhinoceros'.
Parasitism is an important symbiosis—or interaction between two different species living in close physical association—found in marine communities. Different types of marine parasites, including worms, isopods, and copepods, infect a variety of host species, including crabs and fishes.
In a parasitic relationship, one organism benefits at the expense of another. For example, mosquitoes drink human blood, which causes humans to get itchy and can even get them sick.
Protozoa, Helminths, and Ectoparasites are three main types of parasites. Bacteria, Fungi, Viruses, Protozoa, Rickettsia, and Helminth are six main types of pathogens. All parasites are not harmful and do not spread disease to the body of the host.
There are a number of parasites that cause diseases in humans. Parasitic diseases are most common in developing countries in tropical and sub-tropical regions of the world (Figure 3). These places are often hot and humid, conditions which are suitable for the growth of many parasites.
Dioctophyme (=Dioctophyma) renale, the giant kidney worm, is the largest known parasitic nematode infecting humans — adult females can reach over one meter in length. The genus has been spelled as both “Dioctophyma” and “Dioctophyme”.
Parasites are different from bacteria or viruses because their cells share many features with human cells including a defined nucleus. Parasites are usually larger than bacteria, although some environmentally resistant forms are nearly as small.
