• Wuchereria — This is a genus of parasitic filarial nematodes (tiny worms). Wuchereria bancrofti is one of the three types of roundworms that cause lymphatic filariasis, an infection of the lymphatic system. The two other roundworms are Brugia malayi and Brugia timori. Humans contract these through bites by infected mosquitoes. Wuchereria bancrofti is commonly referred to as Filaria worm.
• Ancylostoma — This is a genus of nematodes, commonly called the hookworms, which usually infect the intestines of their hosts. Ancylostoma duodenale (old world hookworm) and Necator americanus (new world hookworm), are the two species common to humans. They feed on the blood of the host and cause condition known as hookworm disease or ancylostomiasis. Contrary to the incorrect match, Ancylostoma does not refer to pinworm.
• Taenia — This genus of flatworms, commonly known as tapeworms, includes some important parasites of livestock and humans. Species like Taenia solium (pig tapeworm) and Taenia saginata (beef tapeworm) can cause taeniasis and cysticercosis in humans. Humans become infected when they consume undercooked beef or pork that contains larval cysts.
• Ascaris — Ascaris lumbricoides, commonly known as the "giant roundworm", is a species of roundworm that lives in the human intestine. It is the cause of a parasitic disease known as Ascariasis, which is a type of soil-transmitted helminthiasis and occurs in people who ingest eggs found in the feces of infected people.
