Helminthiases is one of the most common diseases among children and adults.In the human body, different types of worms can parasitize.Helmines only have an idea that affects the digestive system, in fact, in almost all the internal organs in almost all the internal organs - in the liver, lungs, heart, brain brains and parasitize the subcutaneous tissue and sight.The article is referred to what worms of a person.
Classification
There are many Helminths that can hit a person, below them are most common.The majority of worms apply to 3 groups - vibration, any of the cestodes or nematodes.
Tremtododes are a class of the parasitic worms of about 40 species of worms amazing a person.The most common:
- cat or siberia bicarry (causes opisthorchosis);
- Schistosomes (causes schistosomosis).
CESTODS are ribbon flat worms.Representatives of the cervice have no digestive system.Most people amaze:
- bull tapeworm (causes tusinchosis);
- Pork tapeworm (causes the handcost);
- Echinococcus (causes echinococcosis).
Nematodes round worms, initial cash.General Helminths that affect the person:
- pinworms;
- Askarids;
- Vlashev.
Worms in people are symptoms in the photo (most Helmintons are in the gastrointestinal tract, therefore, the lack of nausea or constipation, guts or permissions, unthinanced or excessive hunger):
Koshachi or Siberian Bicarry
Koshachi or Siberia Bicarry - a small lancolate parasite from a group of liver sacrifices.Derivative agent of the disease opisthorkhosis.The feline reaches the bicarry length, 8-18 millimeters, width-1.2-2 mm.The parasite develops in the organisms of two owners - in the intermediate and final.The intermediate host is Mollyusks and carp fish, a final man.
With the feces of infected people and animals, the eggs fall into fresh reservoirs, they lose mollusks there.Eggs in the body of Mollusk leave the invasive stage - cereals and cereals to Molluzskaya and enter the organisms when the mollusks eat fish.In the body of the fish, the parasite develops up to a meter in cysts, reaches the size of 0.17-0.21 mm.
While eating, an infected fish is infected by a person, the cysts leave the counter on the body, and the stomach and guts pass through the liver and bile channels.They are parasitized in these bodies and start eggs after 10-12 days after the sexual mature stage.In the human body, the two-year-old age of a cat can parasitize until 10-20 years.
Schistosomes
Schistosomes are blood saucers.This flat separate helminths, 4-20 millimeters in length, reaching the width of 0.25 mm.The corpse of the scholosome is located 2nd cups of mouth and abdomen, near each other.Schistosoma Women are longer than men.There is a long-male body in his body, but the woman holds the woman.The diameter of 0.1 mm is a large spike on the ovals, oval shape, the surface of one of the poles.
The latest owner's schistosomes are choosing human worms, small veins of the colon, the abdomen, the small vessels of the uterus, the small vessels of the sac.Worms are fed on the blood, the food items partially swallow through the cuticle.Schistosomes are transported to the intestines and sacs, and where it differs from feces or urine.In freshwater, a larva goes out of the egg, the intermediate host is Mollusk.In the body of Mollusk, Meta Ceriacaria develops in 4-8 weeks.
Bull tape
The bull chain is a strip parasite that causes a teenage disease.These are a great helminths that can grow up to 3-12 meters in length.There is a small head of the parasite body, with 3 mm, neck, as well as about 1,000 segments.After entering the human body, along with unprocessed thermal flesh, the intestinal walls are connected to the intestinal walls of 4 practical glasses.
In the hermaphrodite segments, helminth eggs are put on the eggs, each year an individual puts up to 600 million eggs.These kind of people are parasites in 20 years or more, when such helminates are not treated in time.
Pork
Pork tapeworm, like Bull, there are 4 sermon on the body, but in addition to this, Helmintin's body is also equipped with a double flush of hooks.Reaches two to three meters in length.The pork tapeworm has a small egg, and the uterus on all sides consists of 7 to 12 branches.This is a characteristic feature of Helminton's ability to crawl from the anus of segments.After the output, the peel dries and explodes, so helminth eggs enters the external environment.Tapewormun intermediate master can be a pig and a person.
The main owner is a person.Porents in humans are located in the intestines of the patient where the pork tapeworm, Helminths eggs.Infasion occurs when invasive meat is used.
Exinococcus
Echinococco's subsidiary agent reaches 3-5 millimeters in length.The four suction cups and two holes are from an app that has three - four segments.The last of the segments has a developed reproductive system.The intermediate host is livestock or a person, the last owner is dogs and monsters.The infection occurs as a way of mouth.
Echinococcus enters the intestines where larvae get out of eggs.With the help of hooks, the larvae penetrates the system of the door vascular, where, blood spread to the liver, light and muscle tissue.
Dynamics
Tips - Round worms, enterobiosis pathogens, the most suitable disease of dirty hands.Children's infection is subordinate to children.The infection occurs as a mouth and communication-household road.These worms can be found in feces.
The women of the gender of the pinworms are 5-10 mm in length, men - 3 millimeters.The form of the body for pinworms is a mile-shaped milky white.The end of the body is a little sign in women.Mature worms are parasitizing in the lower parts of a person who clung to the wall with the help of chief vesicles.Pinworms women enter the rectum, creeping eggs and put eggs in the anus area, then die.Delayed eggs are invasive in 4-6 hours.The life of pinworms - one - two months.
Ascarids
Askarides are another representative of round worms class - parasites, ascariasis pathogens.It is a Helminths yellow - Pink, there is a mile stretching in a figurative form.Ascaride women grow up to 20-40 centimeters, men reach 15-25 centimeters in length.Every day, a female female, along with human feces, puts more than 200,000 eggs that differ in the foreign environment in which they invasive in the foreign environment.
The human body is paramed mainly in a localized gastrointestinal tract in the small intestine.It takes about 3 months of full development of an invasive egg to a mature stage.
Vlahev
Vlasodgov - round helminths that generate trichocefeazes.Helminants are a thin brown nematode with a thin dirty front and round back tip.The women of Blazo grow up to 3,515 centimeters and men 3-4.5 centimeters.The larvae of a man's worms parashitis on the phase of the pestle and eggs were localized in Cecum, where the eggs were placed there.Helminths with mass occupation can also catch the large intestine, including.
Every day, Blazo -head-head women slept 3,500 eggs.Helmint eggs have a barrel closed shape, covered with a thick brown shell, is located in the poles of colorless "caps" poles.Eggs can save the occupation of occupation by two years with the presence of favorable conditions, along with intestinal movements of the main owner.The duration of parasitiation in the human bowels is 5-7 years.
