Helminthiases are one of the most common diseases among children and adults.In the human body, different types of worms can parasitize.There is an opinion away from medicine to actually influence the digestive tract, in fact, in almost all internal authorities - liver, lungs, brain, brain, in muscle tissue, subcutaneous tissue and eyes.The article refers to what the worm has a person.
Classification
There is a huge number of helmints that can hit a person, below them are most often.Most worms belong to any of the 3 loads of groups, cestodes or nematodes.
Trematodes are a class of parasitic worms of flat shape, about 40 types of worms that amaze a person.Most often:
- Cat or Siberian Bykarry (causes desisthorischozu);
- Schistosomi (causes Šistosomosis).
Cestodes are ribbons of flat worms.Cestode representatives do not have a digestive system.The most common person is amazed:
- Tapeworm Tag (causes Tusinchozu);
- Pork Tapeworm (causes cysticosis);
- Eachinococcus (causing echinococus).
Nematodes are round worms, primary shit.Common hellets that affect a person:
- Pinworms;
- Askarides;
- Vlashev.
The worms on humans are symptoms in photography (most helmintha affects the gastrointestinal tract, hence nausea and vomiting, diarrhea, or prison, intestinal obstruction, and an appetite disadvantage):
Koshachi or Siberian yard
Koshachi or Siberian bipor - a small parasite of the lanceolate from the group of liver.Causal Agent Disease Desisthorkhoz.In the length of the cat bakery reaches 8-18 millimeters, width-1-2 mm.The parasite develops in the organisms of two owners - medium and financial.Intermediate hosts are mecusks and carp fish, it is the final person.
Together with the feces of infected people and animals eggs fall into fresh tanks, they swallowed the Meplke.In the body of egg mollusks, they reach an invasive stage - cervical cervix, cerva cervix and introduce themselves to the body of the fish carp or enter their organisms when they are mellusks eat fish.In the body of the fish, the parasite develops for a meter in cleanses, its dimensions reach 0.17-0.21 mm.
During meals, infected fish infects people, cysts leave a meter in their body, they cross out of the stomachs and hoses in the liver and bile channels.In these bodies, they remain parasites, and after 10-12 days they reach a sexually mature phase, start to take eggs.In the human body, two-year-old two waits can parasite by 10-20 years.
Schistosomes
Schistosomi are blood conicals.This is flat separate hellets, reaches 4-20 millimeters in length, 0.25 mm wide.Schistosome body is equipped with 2. Vacuuming glasses oral and abdominal, are near each other.Women with schistos are longer and thinner than men.There is a longitudinal slot on the men's body, with it, holds a female.Their eggs in diameter 0.1 mm, oval shape, on the surface of one of the poles are a large spike.
The human worms of the Shistosoma in the role of the ultimate owner choose people, in their organisms that paras in small veins of the colon, abdominal cavity, uterus, bubbles.The worms feed in blood, partially absorb nutrients through cuticles.Schistosomi are transported to the hose and bladder, where they maturize and expire excrement or urine.In freshwater waters, the larva comes out of the egg, her intermediate host is Mollusk.In Mollusk's body, Meta Ceriacaria is developing for Curiale in 4-8 weeks.
Cone
The bull chain is a striptease parasite that causes teennanchosis disease.These are huge helmints that can grow up to 3-12 meters in length.On the body of the parasite there is a small head in diameter to 3 mm, neck, as well as about 1000 segments.After entering the human body, with untreated thermally infected meat, the image is attached to intestinal walls with 4 suction cups.
Helminth eggs are laid in the hermaphrodition segments, one person is taking up to 600 million eggs a year.Such chancelles in humans are parasite in guts of 20 years or more, if there is no timely treatment.
Pork Tapeworm
Pork Tapaworm, like bulls, has 4 suction cups on the body, but next to this, Helminth's body is also equipped with a double whipped hook.Reaches two to three meters in length.Pork Tapeworm has a three-legged ovary, on each side, the uterus has 7 to 12 branches.The characteristic characteristic of this Helmiman is the ability of segments to get out of the anus.After exiting the outside, their grenade becomes dry and bursts, so Helminth eggs enter the external environment.The Tapeworm Intermediate Master can be a pig and a person.
The main owner is a person.Intestinal parasites in humans include pork Tapeworm, Helminths are located in the patient's guts, where they delays their eggs.Infection occurs when invasive meat is used.
Echinokoccus
The cause of echinococosis reaches 3-5 millimeters in length.It consists of a head, on which there are four suction cups and two hook holes, and three - four segments.The last of the segments has a developed reproductive system.The intermediate host is a cattle or person, the ultimate owner are dogs, wolves.Infection occurs as an oral route.
Echinokoccus enters the intestines, where the larvae go out of the eggs.With the help of hooks, the larvae penetrates the system of vena gates, from where they widened together in the liver, light, muscle tissue.
Speakers
Tips - round worms, pathogenic enterobiosis, so -kala disease of dirty hands.To a greater extent, children's infection are subject to children.The infection occurs as an oral and contact method of household.These worms can be found in the feces.
Females Hemical The genus Squeezes reach 5-10 mm long, men-3 millimeters.The shape of the Pinworms body is the milk white in the shape of a spindle.The end of the body in women is a little pointed out.Adult worms parasitize in the lower parts of small and large hoses of a person, which are fastened to the wall with the help of the head.In order to pass the eggs, the female pins enter the rectum, crawl and lay eggs in the anus area, and then die.Delayed eggs become invasive after 4-6 hours.Life expected storage of pins - one - two months.
Askarids
Askarides are another representatives of the class of round worms - parasites, pathogenic ascariasis.These prisoners are yellowish - pink, have elongated spindle figurative shapes, separately.Females Ascaride grows at 20-40 inches, males reach 15-25 inches.Each day an adult ascarida is located more than 200 thousand eggs, which together with the human feces point out into the external environment, where after 12-14 days they become invasive.
The human body is parasil in the gastrointestinal tract, it is localized mainly in a thin hose.The full development cycle from the invasive egg to the ripe phase lasts about 3 months.
Vlashev
Vlasodgov - Round helmets that cause trichophalosis.Helminsants are a thin brown nematod with a thin filamentary front and rounded rear end.Females of Blazo-head grow up to 3.5-5.5 centimeters, and men - up to 3-4.5 inches.The larvae of the worms are localized in cecum, where they are parased in the puberty phase, and eggs are also placed there.With mass invasion, helminths can also take up a large intestine, including the rectum.
Every day, the females of Blazo-head passed 3.5 thousand eggs.Helmint eggs have a shape that is thrown, covered with thick brown shell, colorless "lids" are located on the poles.Eggs fall into the ground together with the movements of the main owner's hose, in the presence of favorable conditions, may maintain invasive properties for up to two years.The duration of the parasicion in human intestines is 5-7 years.
