Crop damage is the result of a complex interaction of the environment, initial nematode populations at planting ...Nematodes, commonly known as “roundworms” because of their round cross section, comprise the second largest phylum in the animal kingdom. Nematodes can live freely but many parasitize humans, most often as accidental hosts.Nematodes are a diverse group of worms that make up the phylum Nematoda. Otherwise known as roundworms, nematodes live as either free-living organisms in terrestrial and …Pathogen. Lesion nematodes belong to the genus Pratylenchus and are soilborne, plant-parasitic roundworms that may cause damage in corn. Individual lesion nematodes range between 0.3 to 0.9 millimeters (0.01 to 0.03 inches) long and thus cannot be seen with the naked eye. These nematodes are known for their broad host-range and are capable of ...Cysticercosis is an infection caused by the larvae of the parasite Taenia solium . This infection occurs after a person swallows tapeworm eggs. The larvae get into tissues such as muscle and brain, and form cysts there (these are called cysticerci).
