Helminthia are one of the most common diseases in children and adults.Different types of worms can parasitate in the human body.There is an opinion that is far from medicine that helminths only influence the digestive tract.In fact, worms can parasitize in almost all internal organs - liver, lungs, heart, brain and in muscle tissue, subcutaneous tissue and eye.The article refers to the worms that a person has.
classification
There are a large number of helminths who can meet a person, including the most common of them.Most worms belong to one of the 3 group trematodes, cestodes or nematodes.
Trematodes are a great parasitic worms of a flat shape, about 40 types of worms that surprise a person.Most frequently:
- Cat or Siberian Bicarry (Cause Opisthorchose);
- Schistosomes (causes schistosomosis).
Cestodes are flat ribbons.Representatives of the cestodes have no digestive system.Mostly one person is amazed:
- Bull fire (causes tusin chose);
- Pig tapeworm (Cystiscosis Cause);
- Echinococcus (causes echinococcosis).
Nematodes are round worms, primary crap.Common helminthen who influence the person:
- Pin pinworms;
- Askarides;
- Vlashev.
Worms in humans are symptoms in the photo (most helminths influence the stomach intestine tract, hence nausea and vomiting, diarrhea or constipation, intestinal engineering, causeless weight loss, lack of appetite or excessive hunger):
Koshachi or Siberian Bicarry
Koshachi or Siberian Bicarry - a small parasite of Lanceolate from a group of liver vacuum.The causal means of the disease Opishorkhoz.In the length of the Katzenbicarry it reaches 8-18 millimeters in width-1,2-2 mm.The parasite develops in the organisms of the two owners - medium and final.The intermediate host is mollusks and carp fish, the finale is a person.
Together with the feces of infected people and animals, eggs fall into fresh reservoirs because they swallow mollusks.In the mollus's body, the eggs reach the invasive stage - cervix, cervix leave Molluska and are inserted into the body of carp fish or enter their organisms when mollusks eat fish.In the body of the fish, the parasite develops in cysts to one meter, its dimensions reach 0.17-0.21 mm.
When eating, an infected fish is infected by one person, cysts leave the measuring device in his body, they go from the stomach and intestine into the liver and bile ducts.They remain parasitically in these organs and start the sexually mature stage to lay eggs after 10-12 days.In the human body, the two -year -old can parasitize a cat of a cat up to 10 to 20 years.
Schistosomen
Schistosomes are bloodless cups.This is a flat, separate helmet that reaches 4-20 millimeters in length, a width of 0.25 mm.The body of the schistosome is equipped with the 2nd suction cup cup and stomach and is located near each other.Schistosoma female are longer and thinner than men.There is a longitudinal shortage on the male body so that it holds the female.Your eggs with a diameter of 0.1 mm, oval shape on the surface of one of the poles are a large spike.
The human worms of the schistosomes in the role of the last owner choose people in their organisms, which they parasitize in small veins of the large intestine, the abdominal cavity, the uterus and the bladder.Worms feed on blood and sometimes absorb nutrients through the cuticles.Schistosomes are transported into the intestine and the bladder, where they ripen and take off with feces or urine.A larva comes out of the eggs in freshwater waters, and its intermediate host is Mollusk.In Mollusk's body, Meta-Ceriacaria develops into curial forms in 4-8 weeks.
Bull
The bull chain is a strip parasite that causes a teenity disease.These are huge helminths that can be up to 3-12 meters long.On the body of the parasite there is a small head with a diameter of up to 3 mm, a neck and about 1000 segments.After entering the human body, the Soliter is attached to the intestinal walls with 4 suction cups together with the unprocessed thermally infected meat.
In hermaphrodite segments, helminths are laid eggs, a person laid up to 600 million eggs annually.Such helminths in humans are parasites in the intestine of 20 years or more if there is no timely treatment.
Pork tapeworm
The pig tapeworm like the bull on the body has 4 suction cups, but in addition the body of the helminth is equipped with a double hook.Reaches two to three meters in length.The pig tapeworm has an ovary of three dops, on each side the uterus has 7 to 12 branches.A characteristic characteristic of this helminth is the ability of segments to crawl out of the anus.After the external output, your shell will be dry and bursting, so that Helminthen eggs reach the outer environment.The intermediate master of the tapeworm can be pigs and one person.
The main owner is one person.The intestinal parasites in humans include pork tapeworm, helminths are in the intestine of the patient, where he lays his eggs.Infections occur when invasive meat is used.
Echinococcus
The causal means of echinococcosis reaches 3-5 millimeters in length.It consists of a head where there are four suction cups and two holes hooks and three - four segments.The last of the segments has a developed reproductive system.The intermediate floor is cattle or a person, the last owner is dogs, wolves.Infection occurs as an oral route.
Echinococcus enter the intestine, where larvae come out of the eggs.With the help of hooks, the larvae penetrate into the gatevene system, from where they spread together with the blood into the liver, light and muscle tissue.
speaker
Tips - round worms, pathogens of enterobiosis, the so -called disease of dirty hands.The infection of children is subject to a greater extent.The infection occurs as an oral and contact -containing manner.You can find these worms in feces.
Women of the helminers of the genre of the pinworms reach a length of 5 to 10 mm, men-3 millimeters.The shape of the body for pinworms is a spindle -shaped milky white.The end of the body in women is slightly pointed.Adult worms parasitize in the lower parts of the small and large intestine of a person and attach themselves to the wall with the help of the head bubbles.To lay eggs, women of pinworms go into the rectum, crawl and lay eggs in the anus area, then die.Fate eggs become invasive after 4-6 hours.The life expectancy of pinworms - one - two months.
Askarids
Askarides are another representative of the class of the round worms - parasites, pathogens of ascariasis.These helminths are yellowish - pink, have separated an elongated spindle of the figurative shape.The Ascarid females grow to 20 to 40 centimeters, the men reach a length of 15 to 25 centimeters.Every day, an adult female ascarida lays more than 200,000 eggs that together with human feces stand out into the outer environment, where they become invasive after 12 to 14 days.
The human body is parasitized in the stomach intestine tract, especially in the small intestine.A complete development cycle from an invasive egg to a sophisticated phase takes about 3 months.
Vlashev
Vlasodgov - round helminthen that cause trichocephalose.Helminants are a thin brown nematode with a thin filamentary front and rounded rear end.Women of the blazo head grow up to 3.5 to 5.5 centimeters and male to 3 to 4.5 centimeters.The larvae of a person's worms are located in the Cecum, where they parasitize into 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.
Every day the females of the Blazo head lay 3.5,000 eggs.Helminteier have a barrel -shaped shape that is covered with a thick brown cover, colorless "lid" on the poles.Eggs, together with the intestinal movements of the main owner, fall in the presence of favorable conditions and can maintain invasion properties for up to two years.The duration of parasitis in the human intestine is 5-7 years.
