Content: This Nematode is not normally fatal and in low numbers may have very little effect on adults. However in heavy doses it can be quite debilitating, especially for children. parasitic Nematode found in the flesh around the stomach cavity of a rainbow trout
The Nematodes infecting mankind include several species of filarial worms. The most important of these are Wuchereria bancrofti and Brugia malayi (which are very similar and cause lymphatic filariasis), Onchocerca volvulus (which causes River Blindness) and Loa loa (which causes Loiasis). Other species are Dranunculus medinensis known as Guinea Worm, Trichinella spiralis causing Trichinosis, Necator americanus and Ancylostoma duodenale causing Hookworm, Enterobius vermicularis causing Pinworms and Trichuris trichuria causing Whipworm or Trichuriasis. Nematode Anatomy
Basically a Nematode is a long hollow tube within which is another tube, the alimentary canal and the reproductive organs. Nematodes are round in cross section. This is because, unlike the other worms that are below them in the phyla table, they maintain their body fluids under great pressure (on average, internal pressure in a nematode equals 70mm of mercury or 1.49 PSI – with a maximum recorded value of 125mm of mercury or 2.41 PSI). To contain this high pressure, nematodes have an extremely tough, yet elastic and flexible cuticle. This cuticle consists of up to 9 layers of proteinaceous fibres.
