Types of parasites in the human body and very divers. The un is one of them, along with Metazoa and protozoa are also viruses, bacteria and fungi that parasitize the human body, although in the medical traditions of viruses and bacteria are not considered parasites.
We consider the main types of endoparasites of man. The appearance of many of them can be seen only with a microscope, and some, especially helminths, affect its size. Let's start with the most simple:
- Giardia along with the liver also cause of hypovitaminosis, anemia and intoxication General of the organization.
- Toxoplasma affect the brain, the eyes, the heart, the muscles, the nervous system, but the special that pose danger to pregnant women because of the risk of serious or death fetal injuries.
- Can cause The amoeba amoebic dysentery, amoebic encephalitis and other dangerous diseases.
- Trichomonas are sources of infectious diseases of the genitourinary system.
The more Marta parasites
Marta endoparasites The most are, of course, helminths (worms), which, according to destinations of estimates, infected more than 80% of the world population.
A large number of these parasites are divided into basic types:
- nematodes – round worms (roundworm, pinworm, the species of Trichinella, whipworm, etc.);
- cestodes – tapeworms (lantecy, pork and veal I had, had, etc.);
- trematodes – worms-flukes (liver, blood, lung, and flukes that live in the intestines).
Sometimes, you can find more General classification, according to which all types of parasites people are divided in:
- luminal (intestinal), parasitic in the intestine;
- tissue, localized in other organs and tissues.
However, the majority of the worms in the different stages of its life cycle and the tissue, and intestinal development period with the corresponding symptoms.
Consider a brief description of the most common types of worms.
Worms (nematodes)
- Roundworm – roundworms are the most common length of 20 to 40 cm, parasites in the small intestine, but first migrate in the human body that affect the blood and the respiratory system. Along with these intestinal parasites can be detected in the liver and the gallbladder, the heart and lungs. The un symptom Marta of ascariasis I allergic reaction.

Adult species that live in the human body in different types of muscles (respiratory, face, etc.), causing muscle pain, fever, inflammation, allergic rash on the skin.
- Vlasoglavy – worms small (length up to 4.5 cm, with the front part of the body
in the form of a thread), the larvae of which with cause trihozefalez diarrhea, abdominal pain acute symptoms and other similar to an appendicitis. As a result of poisoning of the anemia.
Tapeworms (cestodes)
- Had Un, the length of the body and reaching up to 10 m, leads to the development of difillobotrioz with nausea, weakness, vomiting, unstable chair, asthenia and anemia.
- The pork tapeworm has a length of 3 to 8 m, a parasite mainly in the small intestine causes diseases fees: taeniasis with dyspeptic, asthenic-neurotic and syndromes abdominal, and with cysticercosis intoxication, intestinal, allergic and respiratory symptoms. Depending on the location of cysticerci affects the muscles, brain, heart, eyes, etc.
- Veal had, the length of which can reach up to 18 m, and makes the had ox infection and considered to be one of the most types of worms are dangerous. If you do not do deworming, which can stay in the body for 18-20 years! Localized Is in the large intestine, causes severe poisoning with its products and waste, as well as the diarrhea, nausea, vomiting, abdominal pain, anemia, allergic reactions and problems with the nervous system.
- Nan had only a length of 1.5-5 cm source gimenolepidoz with diarrhea, pain and astheno-neurotic syndromes mainly affecting the system, the digestive system and the nervous and the liver.
- Echinococcus is considered to be the smallest tape worm – its length of 2.5 in and 8, rarely 9 mm, but the infection has terrible consequences such as the liver and the lung, where they form cysts and tumors which cause dysfunction of these organs.
Worms-flukes (trematodes)
- Liver Fluke or the liver Fluke has the form of a sheet with a length of 30 to 50 mm and a width of 8-13 mm, has a suction Cup. It damages the sheath of the liver and clog the bile ducts and that is able to completely block the flow of bile. Can lead to cirrhosis, jaundice and liver cancer.

- The lung Fluke has a shape ovoid, red-body brown with small spines, the length of 7.5 to 12 mm, with a width of 4-8 mm. Affects the lungs, causing inflammation, pleural effusion, focal fibrosis, and lung cancer. When the penetration into the brain, causing encephalitis and meningoencephalitis.
- Shistosoma (blood flukes) – dioecious worms with a size of 1-2 cm, the eggs of which cause un increase in the liver, the spleen and lymph nodes, the formacio of polyps in the bowel, diarrhea, granulomatous inflammation, leading to cancer of the bladder.

A variety of parasites in the human body
- Beef The had.
