Chitin helps to increase populations of beneficial soil microbes that feed on root-knot nematodes and provides a level of biological control.Nematodes are difficult vectors to deal with experimentally because of their small size and their rather critical requirements with respect to soil moisture content, type of soil, and, to a lesser extent, temperature. To overcome these problems, five criteria have been proposed for establishing the nematode vectoring of viruses (Brown et al., 1989; Trudgill et al., 1983).Strongyloidiasis is an intestinal infection caused by the parasitic roundworm (nematode) Strongyloides stercoralis.
