Content: However, the majority of nematodes that exist as parasites are found in this class. Parasitic Rhabditea
Parasitic nematodes found in class Rhabditea include Ascaris, Enterobius (e.g. human pinworm), Necator species as well as Wuchereria species. These species infect and cause a variety of diseases in human beings ranging from minor to very serious conditions. For instance, Wuchereria bancrofti, a species belonging to the genus Wuchereria causes a serious condition known as Lymphatic filariasis characterized by the swelling of arms and legs. This is a serious condition that is not only painful, but also causes the disfiguration of arms and/or legs. Compared to other worms in this class that can be found in many regions across the world, this species of nematodes are common in the tropics. On the other hand, intestinal infections caused by such nematodes as Enterobius and Ascaris can be treated and do not usually result in serious health problems. Free-Living Nematodes in Class Rhabditea
One of the best examples of free-living nematodes in class Rhabditea are members of the genus Caenorhabditis. Caenorhabditis elegans, a species of Caenorhabditis is a small, free-living worm found in temperate environments. Apart from nutrition sources in decaying matter, these worms also obtain nutrients from rotting fruits.
