IgE antibodies are thought to react with the parasite to form immune complexes that are bound by macrophages via surface receptors for the Fc region of IgE. These activated macrophages then kill the parasite.
Basophils and mast cells have surface receptors for IgE, and contain histamine, prostaglandins, leukotrienes and proteases. They are involved in immune responses to parasites and in the immediate type of hypersensitivity responses (Ch. 17).
In some cases, parasites clear up on their own, especially in a person with a healthy immune system. If the parasite causes concerning symptoms or may cause complications, doctors will likely order an antiparasitic medication that kills the parasite. Some people choose natural methods to clear their body of a parasite.
Eat more raw garlic, pumpkin seeds, pomegranates, beets, and carrots, all of which have been used traditionally to kill parasites. In one study, researchers found that a mixture of honey and papaya seeds cleared stools of parasites in 23 out of 30 subjects. Drink a lot of water to help flush out your system.
Worms in your gut eventually pass through your digestive system and are excreted in your feces. Even if you don't have any symptoms, you may find signs of worms in your stool.
Protective immunity in some infections is due to a combination of humoral and cellular immunity; in this circumstance parasites are coated with antibody which makes them susceptible to direct cytotoxicity by macrophages, eosinophils, and neutrophils. Antibody alone is protective against some other infections.
Eosinophils as anti-parasite effector cells. Eosinophils accumulate following nematode infection, largely in response to IL-5, a cytokine not only critical for recruitment but also eosinophil differentiation from the bone marrow [98].
Eosinophils. They attack and kill parasites and cancer cells, and help with allergic responses.
In the journal Parasite Immunology, Kamal et al. explains that parasitic worms often weaken the immune system's ability to effectively respond to a vaccine because such worms induce a Th2-based immune response that is less responsive than normal to antigens.

Common global water-related diseases caused by parasites include Guinea worm, schistosomiasis, amebiasis, cryptosporidiosis (Crypto), and giardiasis. People become infected with these diseases when they swallow or have contact with water that has been contaminated by certain parasites.
Giardia is arguably the most common parasite infection of humans worldwide, and the second most common in the United States after pin-worm. Between 1992 and 1997, the Centers for Disease Control and Prevention (CDC) estimated that more than 2.5 million cases of giardiasis occur annually.
Schistosomiasis, also known as bilharzia, is a disease caused by parasitic worms. Although the worms that cause schistosomiasis are not found in the United States, people are infected worldwide. In terms of impact this disease is second only to malaria as the most devastating parasitic disease.
Nonpathogenic intestinal protozoa are single-celled parasites commonly found in the intestinal tract but never associated with illness. They do not harm the body, even in people with weak immune systems.
Grab on to a list of some of the most dangerous parasites on Earth: Brain-eating amoeba, Naegleria fowleri. Naegleria fowleri, also known as brain-eating amoeba, generally grows in warm bodies of water. This parasite can cause brain infection called meningoencephalitis, which causes severe brain irritation.
Adult worms may live up to 17 years in the human body and can continue to make new microfilariae for much of this time.
Should You Be Worried? “While it is widely acknowledged that infections with some parasites can cause significant complications, not all parasites are cause for concern. Some symptoms caused by parasites can clear up on their own, and individuals with a healthy immune system may not experience any symptoms.
The signs of a parasite are often caused by the toxins that it releases into the human bloodstream. Here are the most common symptoms: Unexplained constipation, diarrhea, gas, bloating, nausea or other symptoms of Irritable Bowel Syndrome. You traveled internationally and got diarrhea on your trip.
Weight loss — parasites can cause nausea and poor nutritional absorption, which can lead to weight loss. Chronic fatigue syndrome — parasites steal your nutrients and disrupt your intestinal microbiome, resulting in fatigue and brain fog. Anemia — some parasites feed on red blood cells, which can cause anemia.
However, parasitic infections still occur in the United States, and in some cases, affect millions of people. Often they can go unnoticed, with few symptoms. But many times these infections cause serious illnesses, including seizures, blindness, heart failure, and even death.
How long will symptoms last? Symptoms generally last anywhere from 2 to 6 weeks. In people with weakened immune systems (e.g., due to illness such as HIV), symptoms may last longer.
At times these parasites can even pose a greater threat to our bodies because many of them carry diseases. It is estimated that around 80% of both adults and children have parasites in their gut.
The good news is that most parasitic infections can be prevented, and many are treatable. However, these infections are often undetected and untreated because most people do not know they are infected or at risk, or don't have access to appropriate care.
Treatment of Parasitic Infections
Some drugs (antiparasitic drugs) are designed particularly to eliminate parasites or, in the case of some worm infections, reduce the number of worms enough so that symptoms clear up. Also, certain antibiotics and antifungal drugs are effective against some parasitic infections.
What are parasites? Parasites are any organism that live and feed off of another organism, which means that our bodies are the perfect place for them to live. They eat, lay eggs, secrete toxins, and thrive off of foods such as dairy products, sugar and protein.
