Helminthias are one of the most common diseases in children and adults.In the human body, various types of worms can parasitize.There is an opinion far from medicine that helminthes only affect the digestive tract, in fact, worms can parasitize in almost all internal organs - liver, lungs, heart, brain brain, as well as in muscle tissue, tissues and subcutaneous eyes.The article refers to what a person has.
Classification
There are a large number of helminths who can strike a person, below are the most common among them.Most verses belong to one of the 3 Trimatodes, Cistodes or Nematodes.
Trusts are a class of parasitic worms of a flat shape, about 40 types of worms which are surprised a known person.The most common:
- Cat or Siberian bicarria (causes opisthorchosis);
- Schistosomes (provokes schistosomosis).
Cestodes are ribbon dishes.The representatives of cestodes do not have a digestive system.Most often, a person is amazed:
- Taureau teuin (causes the tininchosis);
- pork tenia (causes cystiscosis);
- Echinococcus (causes echinococcosis).
Nematodes are roundworms, primary shit.Common helminthes affecting the person:
- Pinworms;
- Askarides;
- Vlashev.
Worms in humans are symptoms in the photo (most helminthes affect gastrointestinal tract, hence nausea and vomiting, diarrhea or constipation, intestinal obstruction, weight loss without cause, lack of appetite or excessive hunger):
Koshachi or Siberian bicarria
Koshachi or Siberian bicarria - a small lanceolate parasitic from a group of liver of liver.The causal agent of the Opisthorkhoz disease.In the length of the feline bicarria, it reaches 8 to 18 millimeters, in width-12-2 mm.The parasite develops in the organizations of the two owners - intermediate and final.The intermediate host is molluscs and carp fish, the final is a person.
With the excrement of infected people and animals, eggs fall into fresh tanks, they swallow the molluscs.In the body of the mollusk, the eggs reach the invasive stage - the cervical, the cervicals leave the molluska and are introduced into the body of the carp or enter their organisms when the molluscs eat fish.In the body of fish, the parasite develops a meter in the cysts, its dimensions reach 0.17-0.21 mm.
When you eat, an infected fish is infected with a person, the cysts leave the meter in their body, they go from stomach and intestines to liver and bile canals.In these organs, they remain parasitized and after 10 to 12 days, they reach the sexually mature stage, begin to lay eggs.In the human body, a two -year -old cat of a cat can appear up to 10 to 20 years.
Schistosomes
Schistosomes are blood saucers.It is a flat Helminthes flat, reached 4 to 20 millimeters in length, 0.25 mm wide.The body of the schistosome is equipped with the second oral and abdominal subventy, they are located from each other.Schistosoma females are longer and thinner than men.There is a longitudinal groove on the male body, with it, it holds the female.Their eggs with a diameter of 0.1 mm, the oval shape, on the surface of one of the posts are a large peak.
The human verses of the schistosomes in the role of the final owner choose people, in their organisms which they parasitize in the small veins of the colon, the abdominal cavity, the uterus, the bladder.The worms feed on blood, partially absorb nutrients through the cuticle.Schistosomes are transported to the intestines and the bladder, where they mature and stand out with excrement or urine.In freshwater water, a larva comes out of the eggs, its intermediate host is mollusc.In the body of the mollusc, the meta-Ceriacaria develops in curials in 4 to 8 weeks.
Conic
The bull chain is a tape parasite that causes adolescence disease.These are huge helminths that can reach 3-12 meters in length.On the body of the parasite is a small head with a diameter up to 3 mm, a neck, as well as around 1000 segments.After entering the human body, as well as thermally unprocessed infected meat, the soliter is attached to the intestinal walls with 4 suction cups.
In hermaphrodite segments, Helminthes eggs are laid, annually, an individual lays up to 600 million eggs.These helminthes in humans are parasitic in the intestines aged 20 or over, if there is no treatment in a timely manner.
Pork tenia
The pork tenia, like the bull, on the body has 4 sub-shackles, but in addition to that, the body of the helminthe is also equipped with a double whip of hooks.Reached two to three meters long.The pork tenia has a three ovarian, on each side, the uterus has 7 to 12 branches.A characteristic of this helminthe is the ability of the segments to be released from the anus.After the exit from the outside, their shell becomes dry and bursts, then the eggs of the helminths penetrate into the outside environment.The intermediary master of Ténia can be pigs and a person.
The main owner is a person.Intestinal parasites in humans include pork tenia, helminths are located in the patient's intestines, where he lays his eggs.Infection occurs when invasive meat is used.
Echinococcus
The echinococcosis causal agent reaches a length of 3 to 5 millimeters.It consists of a head, on which there are four suction cups and two hooks, and three - four segments.The last of the segments has a developed reproductive system.The intermediate host is livestock or a person, the final owner is dogs, wolves.The infection occurs in the form of an oral route.
Echinococcus enters the intestines, where the larvae come out of the eggs.Using hooks, the larvae penetrate the door vein system, from where, with the blood, they propagate in the liver, light and muscle tissue.
Speakers
Tips - Rounds, pathogens of enterobiosis, illness so called dirty hands.To a larger extent, children's infection is subject to children.The infection occurs as an oral and contact with the house.You can find these verses in the excrement.
Helminants females of the genus of Pinworms reach a length of 5 to 10 mm, men-3 millimeters.The shape of the body for pine worms is milky white spindle.The end of the body in females is slightly sharp.Adult worms are parasitized in the lower parts of the small and large intestines of a person, attaching to the wall using the head vesicles.In order to lay eggs, pine females enters the rectum, crawl and lay eggs in the anus area, then die.Delayed eggs become invasive after 4 to 6 hours.Pinworms' life expectancy - one - two months.
Askarides
ASKARIDS are another representative of the class of roundworms - parasites, pathogens of Ascariase.These helminths are yellowish - pink, have an elongated spindle of the figurative shape, separately.Ascaride females reach 20 to 40 centimeters, the males reach a length of 15 to 25 centimeters.Each day, an Ascarida adult female lays more than 200,000 eggs, which, with human excrement, are distinguished in the external environment, where after 12 to 14 days, they become invasive.
The human body is parasitized in the gastrointestinal tract, located mainly in the small intestine.A complete development cycle of an invasive egg at a mature stage takes about 3 months.
Vlashev
VLASODGOV - Round Helminthes that cause trichocephalosis.Helminants are a thin brown nematode with a fine front and rounding end.Blazo's head females reach 3.5 to 5.5 centimeters and men at 3-4.5 centimeters.The larvae of the worms of a person are located in the caecum, where they parasitize at the stage of puberty, and the eggs are also laid there.With a massive invasion, helminths can also occupy the large intestine, including the rectum.
Each day, the Blazo -Head females lay 3.5 thousand eggs.Helmint eggs have a barrel -shaped shape, covered with a thick brown shell, colorless "covers" are located on the posts.Eggs fall into the ground with the stools of the main owner, in the presence of favorable conditions, they can maintain invasion properties up to two years.The duration of parasitization in the human intestines is 5 to 7 years.
