worm

 [werm]
1. any of the soft-bodied, elongated, naked invertebrates of the phyla annelida, acanthocephala, aschelminthes, and platyhelminthes; called also vermis. Worms are often found as parasites in humans and other animals; in North America the most common of these are roundworms and tapeworms. flukes are a serious problem in other parts of the world. Most worm infections are transmitted from person to person via feces that contaminate food and water. Serious worm infections may cause anemia, listlessness, fatigue, irritability, abdominal pain, diarrhea, and weight loss. Parasitic worms usually live in relative balance with their human hosts, taking enough nutrients to survive without destroying the health of the host. However, they reduce the strength and energy of the bodies they inhabit, often produce very uncomfortable symptoms and should never go untreated. Suspected cases of worms should be brought to the attention of a health care provider; self-treatment is likely to be ineffective and can be harmful. Effective medications against worms are available by prescription.

Important species include Dracunculus medinensis (dragon, guinea, Medina, or serpent worm), Enterobius vermicularis (seat worm or pinworm), Loa loa (African eye worm), Moniliformis (phylum Acanthocephala, thorny-headed worms), Oxyspirura mansoni (Manson eye worm), Pentastomida (tongue worm), Strongylus (palisade worm), Thelazia (eye worm), and Trichinella spiralis (pork or trichina worm).

GUINEA WORM : Guinea worm being removed from ulcer

guinea worm

A nematode worm (Dracunculus medinensis) that is a parasite affecting subcutaneous tissues of humans and animals, found in tropical Africa and South Asia. The worm causes infection when its larvae are drunk in unfiltered or unsanitary water. The larvae enter the body through the stomach or duodenum, migrate through internal organs, and become adults. After mating, the adult female burrows to the subcutaneous tissue, often of the leg. The worm has been eradicated in Asia. See: Medina worm

Patient discussion about worm

Q. how will i know if i have a tape worm in my body?

A. Most people who are infected with tapeworm don't show symptoms.
It's possible you might notice segments of the adult tapeworm (proglottids) in your stool. Other possible signs and symptoms include:

Nausea
Weakness
Loss of appetite
Abdominal pain
Diarrhea
Weight loss and inadequate absorption of nutrients from food

If you suspect you have a tapeworm you'll need your doctor to check your stool or send samples to a laboratory for testing. A laboratory may use microscopic identification techniques to check for eggs or tapeworm segments in your feces.

Q. baby has worm in stool 6 monthold

A. There are many treatments, but as far as I know they require prescription, so consulting a pediatrician may be necessary.

However, you may read more here: http://en.wikipedia.org/wiki/Intestinal_parasite

Q. Is it possible to have pin worm on directly on the skin of your fore arms? I've had this condition for more than a year. The only thing that makes a difference is something to kill parasites. Nothing works efficiently. I itch all over beside having big sores on my arms and back. I've hade blood test that show that there are no parasites in the blood. So now what do I do? I am constantly digging this out of my skin, and the buggars jump.

A. I'm seeing a dermatologist. They said it wasn't scabies. That's what I thought it was at first. I keep breaking out in new places. The Dr. say's it's dermititous, but I'm seeing something different. Went I first broke out with this I felt crawly in the area I now have the sores.
