Elmintii are one of the most common diseases between children and adults.In the human body, various types of worms can parasitic.There is an opinion far from the medicine that the Elmininti affect only the digestive tract, in fact, the worms can parasitic in almost all internal organs: liver, lungs, heart, brain brain, as well as in muscle tissue, in subcutaneous tissue and in the eye.The article refers to what a person has a person.
Classification
There are a huge number of helminths that can hit a person, below are the most common.Most of the worms belong to one of the 3 trimmod groups, basketballs or nematodes.
The Trematodes are a class of parasites of flat shape, about 40 types of worms that will amaze a person.The most common:
- Cat's or Siberian bicarry (Opistorchosis cause);
- Schistosomi (due to schistosomosis).
The basketballs are ribbon dishes.The representatives of the Cestodes do not have a digestive system.Very often, a person is amazed:
- Tenia Toro (due to Tusinchosi);
- pork tension (cause cystiscosis);
- Echinococcus (due to echinococcosi).
The nematodes are round worms, primary shit.Common elmints affecting the person:
- Pinworms;
- Askarides;
- Vlashev.
Verms in humans are symptoms in the photo (most of the helminths influence the gastrointestinal tract, therefore nausea and vomiting, diarrhea or constipation, intestinal obstruction, weight loss without cause, lack of appetite or excessive business):
Bicarry Koshachi or Siberian
Koshachi or Siberian Bicarry - A small parasite of Lanceolate from a group of liver windy cars.The causal agent of the Opisterkhoz disease.In the length of the feline bicarry, it reaches 8-18 millimeters, in width-1,2-2 mm.The parasite develops in the organisms of the two owners - intermediate and final.The intermediate guest is molluscs and carp fish, the final is a person.
Together with the stools of infected people and animals, the eggs fall into fresh tanks, there swallowing molluscs there.In the body of the mollusk, the eggs reach the invasive - cervical phase, the cervical leaves molluska and are introduced into the body of carp fish or enter their organisms when the molluscs eat fish.In the fish of fish, the parasite develops one meter in cysts, its size reach 0.17-0.21 mm.
When eating, an infected fish is infected by a person, the cysts leave the meter in his body, pass from the stomach and the intestine to the learned of the liver and the biliary.In these organs, they remain parasites and after 10-12 days they reach the sexually mature phase, they begin to lay the eggs.In the human body, the two years of a cat can parasite up to 10-20 years.
Schistosomi
Schistosomes are blood saucers.This is a separate dishes, it reaches 4-20 millimeters in length, 0.25 mm wide.The body of the schistosoma is equipped with 2nd suction cups or oral and abdominals, they are found on each other.Schistosome females are longer and thinner than males.There is a longitudinal furrow on the male body, with it, holds the female.Their eggs with a diameter of 0.1 mm, oval shape, on the surface of one of the poles are a large peak.
The human worms of the schistosomes in the role of the final owner choose people, in their organisms that parasitize in small colon veins, abdominal cavity, uterus, bladder.The worms feed on blood, partially absorb the nutrients through the cuticle.Schistosomi are transported to the intestine and the bladder, where they mature and distinguish themselves with stool or urine.In fresh water waters, a larva comes out of eggs, its intermediate guest is mollusc.In the body of the mollusk, metarcaria develops in the Curia in 4-8 weeks.
Toro Rastamation
The Tori chain is a stripes parasite that causes adolescence disease.These are enormous helminths that can grow up to 3-12 meters in length.On the parasite body there is a small head with a diameter of up to 3 mm, a neck and about 1000 segments.After entering the human body, together with the unprocessed meat infected thermally, the soliter is attached to the intestinal walls with 4 suction rugs.
In the hermaphrodite segments, elmininti eggs are laid, every year an individual lay down up to 600 million eggs.Such helminints in humans are parasites in the 20 -year intestine or more, if there is no timely treatment.
Pork
Pork tension, like the bull, on the body has 4 suction cups, but in addition to this, the body of the helmet is also equipped with a double whisk of hooks.Reaches two or three meters in length.The pork tension has a three -double ovary, on each side the uterus has 7 to 12 branches.A characteristic of this elminto is the ability of the segments to crawl out of the anus.After exiting the outside, their shell becomes dry and breaks out, then the Elminto eggs enter the external environment.The intermediate master of the tension can be pigs and a person.
The main owner is a person.Intestinal parasites in human beings include pork tapeworm, the helminths are found in the patient's intestine, where it lays eggs.The infection occurs when invasive meat is used.
Echinococcus
The causal agent ofchinococcosi reaches 3-5mm in length.It consists of a head, on which there are four suction rugs and two hook holes and three - four segments.The last of the segments has a developed reproductive system.The intermediate host is the cattle or a person, the final owner is dogs, wolves.The infection takes place as an oral route.
Echinococcus enters the intestine, where the larvae leave the eggs.With the help of the hooks, the larvae penetrate the vine of the gate, from where, together with the blood, they spread in the liver, light and muscle tissue.
Speakers
Suggestions - Round worms, pathogens of entertainable, the disease so called dirty hands.To a greater extent, children's infection is subject to children.The infection takes place as oral and contact way.You can find these worms in the stool.
The females of the elf of the Pinworms genre reach 5-10 mm in length, male-3 millimeters.The shape of the body for the Pinworms is whitish white in the shape of a spindle.The end of the body in the females is slightly pointed.Adult worms are parasites in the lower parts of a person's tenuous and large intestine, attaching to the wall with the help of the head vesicles.To lay the eggs, Pinworms females go to the rectum, crawl out and lay their eggs in the anus area, so they die.Delayed eggs become invasive after 4-6 hours.Pinworms' life expectancy - one - two months.
Askarids
Askarides are another representative of the class of round worms: parasites, pathogens of the ascariasis.These helminths are yellowish: pink, they have an elongated melted of the figurative form, separately.Ascaride females grow up to 20-40 centimeters, males reach a length of 15-25 centimeters.Every day, an Ascarida adult female lays over 200 thousand eggs, which, together with the human feces, stand out in the external environment, where after 12-14 days they become invasive.
The human body is parasitic in the gastrointestinal tract, mainly located in the small intestine.A complete development cycle from an invasive egg to a mature phase takes about 3 months.
Vlashev
Vlasodgov - Round elmints that cause trichocephaly.The helminians are a thin brown nematodo with a thin filamentous front part and a rounded rear part.Blazo head females grow up to 3.5-5.5 centimeters and males at 3-4.5 centimeters.The larvae of a person's worms are located in the Czech, where parasites to the stage of puberty, and the eggs are also laid there.With enormous invasion, the helminths can also occupy the large intestine, including the rectum.
Every day, the blazo females -head lay 3.5 thousand eggs.The hedge eggs have a rod shape, covered by a thick brown shell, the colorless "lids" are located at the poles.The eggs fall to the ground together with the intestinal movements of the main owner, in the presence of favorable conditions, can maintain invasion properties up to two years.The duration of parasitization in the human intestine is 5-7 years.
