hello, i found something quite interesting information on nematodes. i apologize the print is so small for those who cannot see well. use the zoom feature, if need be to read it better on computer window. should be a page icon.the source of the information is a genome sequencing center. yes, nematodes occur naturally in vast numbers, but are also used in pest control and cotton crops. yes, some are even genetically modified by man. they can reside in insects (insect vector) and are one of the organisms involved in morgellons disease. nematodes can be in the soil, affect plants animals and humans alike. they are a tube within a tube, but are nonetheless are physically a very complete organism. many humans around the world are already infected with one type or another of nematodes. and so many varieties, goodness. here is the link to explore the world of nematodes, courtesy of a genome sequencing center:
