The morphological characters most useful in the classification and identification of terrestrial nematodes, focusing in particular on the plant-parasitic groups, are discussed. These include the cuticle, alimentary canal and an array of mostly sensory cuticular organs that have many diagnostic features useful to taxonomists.

Introduction. The filariae are thread-like parasitic nematodes (roundworms) that are transmitted by arthropod vectors. The adult worms inhabit specific tissues where they mate and produce microfilariae, the characteristic tiny, thread-like larvae. The microfilariae infect vector arthropods, in which they mature to infective larvae.

Medical Care Nematode infections need to be identified and treated accordingly. In dracunculiasis, the best treatment is direct removal of worms from tissue, …

Nematodes are a diverse group of invertebrates abundant as parasites or free-living forms in soil, freshwater, and marine environments.
