Quality Testing for Fabric. If you've bought fabric upholstery before, you know that the fabric is often the first thing to show signs of wear and age. Most likely, the quality and longevity of the fabric is just as important to you as the construction of the furniture itself.
By Dr Ananya Mandal, MD. Helminths are parasitic worms that feed on a living host to gain nourishment and protection, while causing poor nutrient absorption, weakness and disease in the host.These worms and larvae live in the small bowel and are referred to as intestinal parasites.ome of the features of the different groups of the helminths include: 1  The trematodes or flatworms are flat, leaf-shaped and unsegmented. 2  Nematodes are cylindrical and have lips, teeth and dentary plates. 3  The cestodes or tapeworm is segmented and hermaphroditic.
Many, but not all, of the worms referred to as helminths belong to the group of intestinal parasites. An infection by a helminth is known as helminthiasis, soil-transmitted helminthiasis, helminth infection or intestinal worm infection.elminths are worm-like organisms living in and feeding on living hosts, receiving nourishment and protection while disrupting their hosts' nutrient absorption, causing weakness and disease. Those that live inside the digestive tract are called intestinal parasites.
