Just thought I see two parasitical worm types missing and we should complete the set.
This one is unique in that it has to have a human host to live unlike most of its cousins.
There are three kinds and are more serious then the rest. One type lives in the skin and tissue, the second in lymphatic system the third around organs like the heart and lungs.
All of this family can be transmitted through the blood. Heart worm is a common one people treat the dog for we also have a similar critter to worry about and is transmitted human to human the same way mosquitoes. (sorry alskann). This represetn eight different species.
Here is soem hard core desciption of the illnesses that can be caused compliments of www.allaboutworms.com

The parasites Wuchereria bancrofti, Brugia malayi, and Brugia timori cause lymphatic filariasis. Worsening symptoms often lead to a condition known as elephantiasis, which causes unusually large swelling in the extremities. River blindness, technically called onchocerciasis, is also a serious condition as this filarial worm - Onchocerca volvulus - is responsible for lesions on the eye and diseases of the skin. Infections caused by the loa loa, or eye worm, may include swelling and skin eruptions. As the loa loa worm migrates through the eyeball, the sensation is psychologically unpleasant as well. Mansonella streptocerca is a third species known to reside in skin and deeper tissue. Mansonella perstans and Mansonella ozzardi inhabit the stomach and lung cavities and are also found, although less often, around the heart. Animal heartworms, also classified as filariae, very rarely may invade the human system and migrate to the lungs. They cannot survive inside a human body, but will cause scar tissue and may be mistaken for a cancer nodule. In some cases, pain and a persistent cough will alert a doctor to the condition, but the node itself will cause no long-term harm. Filarial worm infestations occur in several countries, including Australia, Africa, the Philippines, Asia, and South America. And, somewhat surprisingly, human worm infections are one of the leading causes of disability, especially those that affect the eyes and the lymph vessels. |
