Black worms in stool Causes: Black worms in stool Image source: solvingtheibspuzzle.com. There are many types of worms like Hookworms, Roundworms, Pinworms, Whipworms, Tapeworms, etc. Which can infest our body and cause symptoms. Black worms in stool are caused due to many reasons, the main being unhygienic practices. Let us explore them further. The adult parasite or its eggs are shed in the stool of humans or animals. This can then contaminate water sources suahc as rivers and lakes as is the case with open sewage or poor water treatment practices. Drinking, bathing or irrigating crops with this contaminated water then allows the parasites to enter the body. Treatment for colon parasites involves the collection of a stool sample which can be analyzed to determine which parasites are present, and the administration of medication to kill the parasites. It is possible for people to be coinfected with multiple parasites, which can complicate treatment and require the use of multiple medications to. A single worms can live up to 15 years in the human body. Trichinella Parasites (Trichinella spiralis) Just about any symptom known to man can be caused by the various stages of trichinosis infection, which can masquerade as at least fifty more familiar diseases ranging from flu to generalized and specific aches and pains. Infect about 25% of the world's population. The eggs leave the body with the stool and hatch two days later in the soil. The larvae enter the human body through the skin, usually through the soles of children and others who go barefoot.

What Are Intestinal Worms (Helminths)?

Human intestinal worms are parasites that live in the human intestine, eat bowel content or suck blood from the intestinal wall. Intestinal worms may cause severe infection,s predominantly in children in tropical and subtropical areas. It is more common in developing nations where proper toilet and sewage facilities are limited.

The presence of parasites of any kind (including intestinal worms) in or on the body is referred to as an infestation. A helminth is a medical term for intestinal worms. Therefore intestinal worms are a helminth infestation. These human intestinal parasites usually gain entry into the gut through the mouth, via contaminated food or water. Some foods, specifically some animal meats, are more likely to transmit these human intestinal worms.

Symptoms of Infestation With Intestinal Worms

Intestinal worms may live in someone’s intestine for years without causing any symptoms. General symptoms may appear few weeks or several months after infestation and include paleness, weakness, tiredness (from anemia due to lost blood sucked by worms), restlessness, disturbed sleep and weight loss (due to loss of nutrients used by worms). Abdominal symptoms can last from weeks to months and include:

• Distended belly
• Foul smelling breath or gas
• Loss of appetite
• Vomiting
• Loose bowel movements or diarrhea
• Worms, their parts or eggs can be sometimes found in the stool
• Itchy skin rash
• Swelling around the eyes
• Swollen itchy bump on the site of the parasite entry (usually on the foot).

Sources of Human Intestinal Worm Infection

Worm eggs, shed in the stool of humans or animals infected with adult worms, can contaminate soil or water. Once outside the body, eggs need several days or weeks to develop into the infective stage (cysts) or immature worms (larvae) that may be ingested when you eat with soil-contaminated hands or when you eat raw unwashed vegetables.

Another source of intestinal worms is undercooked infected meat of domestic pig, freshwater fish or wild animals (bear, walrus, etc.). One can also be infected by ingesting dog’s fleas that have ingested parasitic eggs. Children may contract infection from sandboxes contaminated with pets’ stool. Certain types of immature worms may penetrate through your skin during swimming or walking barefoot. When these parasites reach the small or large intestine they grow into adult worms. Common garden worms usually do not cause illness in human.

How Intestinal Worms Cause Disease?

Adult worms, which may be from 1 millimeter to several meters long, invade the bowel wall and suck the blood from it, or live freely in the intestine and utilize nutrients from the bowel content. The result are small intestinal or colonic inflammation and ulcers, anemia, and protein, iron and vitamin (mainly A, C, B12) deficiency. Intestinal obstruction may occur in severe cases. Larvae may migrate to other organs (liver, spleen, bladder, muscles, lungs, brain), where they form cysts and trigger allergic inflammation.

Common Human Intestinal Worms

A. Roundworms (Nematode)

• The large roundworms (Ascaris lumbricoides) are found worldwide. These worms are several inches long and thick as a pencil (Picture 1).
• Hookworms (Necator americanus, Ancylostoma duodenale) are mostly found in tropical areas; they are about a half of inch long. These worms may be contracted by walking barefoot as they penetrate through the skin. Once in the intestine, they suck blood from the intestinal wall.
• Whipworm (Trichuris trichiura) cause an infestation known as trichuriasis.
• Threadworms
  • Strongyloides stercoralis
  • Pinworm or seatworm (Enterobius vermicularis) is half an inch long, white worm; its egs cause anal itch.
• Trichinella spiralis causes an infestation known as trichinosis. It may be acquired by eating undercooked contaminated pork. Parasites move from the intestine into muscles and other organs where they form cysts – encapsulated forms, which are hard to eradicate. Main symptoms are abdominal pain, muscular and joint pain, swelling of the eyes and skin rash.

B. Flukes (Trematoda)

• Schistosoma mansonicauses intestinal schistosomiasis (bilharziasis), mainly in Africa, Middle East, Caribbean and South America. It is about half an inch long and 1 millimeter thick. Adult parasites live in intestinal veins and release eggs into the intestinal hollow. Diagnosis is made by finding eggs in the stool and urine.

C. Tapeworms (Cestoda)

• Fish tapeworm (Diphyllobothrium latum) is contracted by infected freshwater fish. It may exceed 10 meters in length and is found in Europe, Russia and the United States.
• Beeftapeworm (Taenia saginata) and pork tapeworm (Taenia solium) may be contracted by undercooked beef or pork, respectively. This infestation is referred to as taeniasis. It is more frequently seen in rural areas, worldwide. Adult worms may be over 20 meters long.
• Dog tapeworm (Dipyllidium canium) is common in dogs and cats. Humans are (rarely) infected by ingesting dog fleas, infected with tapeworm larvae. Rice-sized particles can be found in the stool.

Trichicara cati or Trichicara canis can be attracted by ingesting eggs in cat’s or dog’s stool, respectively. After ingesting the egges it develops into larvae that migrate through the body organs, like the lungs. Common symptoms are fever and cough.

How Are Intestinal Worms Diagnosed?

If you suffer from unexplained abdominal bloating, diarrhea, weakness or weight loss, your doctor should suspect intestinal worms (or other intestinal parasites) as a possible cause. Diagnosis is confirmed by stool test for ova and parasites (O&P test). Hemoccult can reveal blood in the stool. Blood tests can reveal anemia (low ferritin and low red cells), low levels of vitamins A, C or B12, antobodies against certain worms, or elevated levels of eosinophils and IgEantibodies. Pinworm eggs from anal region can be collected by adhesive tape test.

Treatment of Intestinal Worms

A single dose of anti-worm drug, like mebendazole (safe for pregnant women), albendazole, diethylcarbamazine, ivermectin or praziquantel kills parasites in most cases. For some days after the eradication, a stool-to-mouth auto-infection with eggs is still possible. Untreated infestations may last for years.

Prevention of Intestinal Worms

The following should prevent you from attracting intestinal parasites:

• Wash your hands after visiting toilet, touching soil or pets, and before meal
• Tell kids to avoid touching mouth and nose with their hands
• Do not walk barefoot and swim in lakes in tropical areas
• Avoid suspicious restaurants with poor hygiene
• Cook meat and fish well
