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.
Parasitism in Humans
The organisms that parasitize humans include fungi, leeches, lice, viruses, protozoa, tapeworm, etc. Few organisms such as Helminthes live inside the intestine of the host and causes several infectious diseases, such as jaundice, malnutrition, diarrhoea, etc.

In a healthy relationship, partners take turns doing favors for each other whenever one person needs a little help. In a parasitic relationship, one partner is always doing favors for the other and getting nothing in return.
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.
In Humans. Over 100 different types of organisms can parasitize humans including fungi, leeches, lice, ticks, mites, tapeworms, protozoa, viruses, and helminths.

Parasites and bacteria have co-evolved with humankind, and they interact all the time in a myriad of ways. For example, some bacterial infections result from parasite-dwelling bacteria as in the case of Salmonella infection during schistosomiasis.
Mutualism is a win-win situation for both organisms because both benefit from the relationship. With commensalism, one organism benefits while the other is unaffected. Then there's parasitism, where one organism (the parasite) benefits at the expense of the other (the host).
Parasites also influence host behavior and fitness, and can regulate host population sizes, sometimes with profound effects on trophic interactions, food webs, competition, biodiversity and keystone species. These interactions suggest that parasites are integral components in shaping community- and ecosystem structure.
Intestinal parasites that remain prevalent in the United States include Enterobius vermicularis, Giardia lamblia, Ancylostoma duodenale, Necator americanus, and Entamoeba histolytica.
The most common intestinal protozoan parasites are: Giardia intestinalis, Entamoeba histolytica, Cyclospora cayetanenensis, and Cryptosporidium spp.

There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites.
In the United States, the most common foodborne parasites are protozoa such as Cryptosporidium spp., Giardia intestinalis, Cyclospora cayetanensis, and Toxoplasma gondii; roundworms such as Trichinella spp. and Anisakis spp.; and tapeworms such as Diphyllobothrium spp. and Taenia spp.
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.
