Digestion. In intestinal nematodes, digestion usually begins as food particles enter the pharynx, or even earlier in species that feed by extracorporeal digestion of host tissues. Nippostrongylus brasiliensis, for instance, releases histolytic enzymes from...

Nematoda Roundworms, nematodes, hookworms, plant parasites Round worm-like body, complete digestive systems terrestrial, freshwater and marine many are parasites... 

Nematodes are elongated roundworms that possess a complete digestive system, including both a mouth and an anus (Figure 36.3). They cause infections of the intestine as well as the blood and tissues. Figure 36.4 summarizes the infections caused by nematodes, and the common therapies used for these infections. 

The very small aquatic and terrestrial tardigrades with about 700 species possess stylets behind their mound opening, which are associated with a large gland. It is not exacdy known whether those predatory species feeding on Rotatoria, nematodes, enchytraeids, or other tardigrades secrete either digestion enzymes or toxins that may immobilize the prey.24... 

One of the most infamous nematodes is Trichinella spiralis, a parasite that lives its larval stage encysted in the muscle tissue of animals, including swine, and make their way into the intestinal tissue of humans who happen to digest infected, undercooked pork. 

Infections by intestinal roundworms is prevalent in pigs throughout the world. The presence of nematodes in the digestive tract of pigs is associated with... 

The infestations by intestinal roundworms in fowls is responsible for a number of gastrointestinal problems. The common nematodes of the digestic tract of poultry are Heterakis gallinarum, H. indicn, Ascaridia galli, Capillaria spp., Strongyloides avium and Trichostrongylus tenuis.
