Worms in humans

Helminthiases is one of the most common diseases in children and adults.In the human body, many different types of worms can parasitize.There is an opinion that is far different from helminths that affect the gastrointestinal tract, in fact, the depth can be parasitized in most internal organs - liver, lungs, heart, brain, as well as in muscle tissue, subcutaneous tissue and eye.The article refers to what a worm has a person.

Classify

There are a large number of helminths that can beat one person, here is the most common among them.Most of the worms belong to any of the 3 groups-Trematodes, Cestodes or nematodes.

Trematodes is a parasitic worm of flat shape, about 40 types of worms that one is known.Most popular:

  • Bicarry Cat or Siberian (causing opisthorchosis);
  • Schistosome (causing Schistosomosis).

Cestodes are flat worms.Cestodes representatives have no digestive system.Usually, a person was surprised:

  • Tapeworm bull (causing tusinchosis);
  • Pork tapeworm (causing cystiscosis);
  • Echinococcus (causing echinococcosis).

Nematic glands are round worms, crap.Popular helminths affect people:

  • roundworm;
  • Askarides;
  • Vlashev.

Worms in humans are symptoms in the image (most helminths affect the gastrointestinal tract, so nausea and vomiting, diarrhea or constipation, intestinal obstruction, countless weight loss, lack of appetite or hunger too much):

Koshachi or Siberian Bicarry

Koshachi or Siberian Bicarry

Koshachi or Siberian Bicarry - a small parasite of Lanceolate from a group of liver suckers.Pathogens of opisthorkhoz disease.In the length of the two cats, it reached 8-18 mm, width-1.2-2 mm.The parasite develops in the organisms of the two owners - intermediaries and the last.Intermediate server is soft body and carp, the final is a person.

Along with the feces of the infected person and animals, the eggs fall into fresh reservoirs, where they swallow soft body.In the body of soft body, eggs to the invasive stage - cervix, cervix leaves soft body animals and is put into the carp body, or enters their creatures when soft animals are eating fish.In the body of Pisces, parasites grow into one meter in cyst, its size reaches 0.17-0.21 mm.

When eaten, an infected fish is infected with one person, the cysts leave the clock in the body, they are transmitted from the stomach and intestines to the liver and bile duct.In these agencies, they are still parasitic, and after 10-12 days, they reach the stage of sexual adulthood, starting to lay eggs.In the human body, a two-year-old child of a cat can parasitize up to 10-20 years.

Schistosome

Schistosome is a blood plate.This is a separate helminth, reaching a length of 4-20 mm, a width of 0.25 mm.Schistosome's body is equipped with the second and abdominal suction cup, they are placed close to each other.Schistosoma children are longer and thinner than men.There is a long vertical groove on the male body, with it, he keeps the female.Their eggs have a diameter of 0.1 mm, oval, on the surface of one of the poles is a large spearhead.

The human worms of the Schistosome are in the role of the last owner to choose people, in their organisms, they parasitize in the small veins of the colon, the abdominal cavity, uterus, bladder.The worms eat blood, partially absorb nutrients through the epidermis.Schistosomes are transported to the intestine and bladder, where they are ripe and prominent with feces or urine.In fresh water, a larvae out of the egg, its intermediate host is soft body.In the body of soft body, Meta Ceriacaria develops into a curvature for 4-8 weeks.

Bull Taper

Bull Taper

The bull sequence is a strip parasite that causes teenagers.These are large rigs that can increase to 3-12 meters.On the body of the parasite is a small head with a diameter of up to 3 mm, neck, as well as about 1,000 segments.After entering the human body, along with untreated heat, the Soliter is attached to the intestinal walls with 4 suction cups.

In Hermaphrodite segments, helminths are placed, an individual produces 600 million eggs every year.Introducing such a parasite in the intestine for 20 years or more, if there is no timely treatment.

Pork tapeworm

Pork flukes, like a male beef, on the body there are 4 suction cups, but in addition, the body of the helminth is also equipped with a double hook.Reaching a length of two to three meters.Pork flukes have ovarians, on each side, the uterus has from 7 to 12 branches.A characteristic feature of this helminth is the ability of segments to crawl out of the anus.After escaping outside, their skin becomes dry and broken, so helminth eggs penetrate the outside environment.Intermediate masters of tapeworm may be pigs and one person.

The owner is a person.The intestinal parasites in humans include pork tapeworms, helminths are placed in the patient's intestines, where he lays eggs.Infections occur when invasive meat is used.

Echinococcus

The pathogens of Echinococcosis reached 3-5 mm in length.It consists of a head, on which there are four suction cups and two holes, and three - four segments.The final segments have a development system.The intermediary owner is breeding or one person, the last owner is dogs and wolves.Infections occur in the form of oral.

Echinococcus goes into the intestine, where the larvae out of the egg.With the help of hooks, the larvae enter the portal vein system, from where, along with blood, they spread into the liver, light, muscle tissue.

Advice - Roundworms, pathobiosis, such disease of dirty hands.To a larger extent, children's infections suffer from children.Infections occur as drinking and contact in a way.You can find these worms in the feces.

The children of Heelminants belong to the limb of the pinworms worm with a length of 5-10 mm, 3 mm men.The shape of the body for worms is opaque white axis.The end of the female body is slightly pointed.Adult worms parasitize in the lower parts of a small intestine and a large person, attached to the wall with the help of the first bags.To lay eggs, the battery worms into the rectum, crawling and laying eggs in the anus area, then dies.The delayed egg becomes invasive after 4-6 hours.Pinworms's life expectancy - one - two months.

Askarids

Askarides are another representative of the roundworm - parasite, pathogens of Ascaria.These helminths are yellow - pink, with a long slender axis of the image shape, separate.Ascaride's females increased to 20-40 cm, males reached 15-25 cm long.Every day, an Ascarida mature woman lays more than 200,000 eggs, along with human stool, standing out with the external environment, where after 12-14 days they are invasive.

The human body is parasitic in the digestive tract, which is localized mainly in the small intestine.A fully developed cycle from an invasive egg to adulthood takes about 3 months.

Vlashev

Vlasodgov - Introducing round causes Trichocephalosis.Helminants is a thin brown nematode with a thin front string and round back.The children of Blazo head increased to 3.5-5.5 cm and men to 3-4.5 cm.The larvae of a person's worms are localized in the cecum, where they parasitize in puberty, and the eggs are also placed there.With a large invasion, helminths can also occupy large intestines, including rectum.

Every day, the female of blazo -head lays 3.5 thousand eggs.Telmint eggs are shaped like a gun barrel, covered with a thick brown shell, colorless lids, placed in columns.Eggs fall into the soil along with the intestinal movements of the main owner, with the presence of favorable conditions, they can maintain invasion properties up to two years.The parasitic time in human intestines is 5-7 years.
