Helminthias is one of the most common diseases in children and adults.In the human body, various types of worms can be parasites.There are opinions far from medicines that only affect the digestive tract, in fact, the worm can be parasites in almost all internal organs -liver, lungs, heart, brain brain, and in muscle tissue, subcutaneous tissue and eyes.The article refers to what is on one's worm.
Classification
There are a large number of helminths that can hit someone, below is the most common of them.Most worms belong to any 3 group-trematoda, cestod or nematoda.
Trematodes are a class of parasite worms flat, about 40 types of worms that are known for a person.The most common:
- Paint or siberia bicarry (causing opisthorchosis);
- Schistosomes (causing schistosomosis).
Cestod is a flat worm.Representatives -Cestod representatives do not have the digestive system.Often, someone is impressed:
- Bull tapeworm (causing tusinchosis);
- pork worms (cause cystacosis);
- Echinococcus (causing echinococcosis).
Nematoda is a circular worm, the main blank.The ordinary helminths that influence the person:
- Pinworms;
- Soldiides;
- Vlashev.
Worm in humans is a symptom in the photo (most helminths affect the gastrointestinal tract, thus nausea and vomiting, diarrhea or constipation, intestinal obstruction, weight loss, lack of appetite or excessive hunger):
Koshachi or Siberia Bicarry
Koshachi or Siberia Bicarry - a small parasite in the form of an blade from a group of liver inhalers.Opisthorkhoz's disease agent.In Feline Bicarry's length, it reaches 8-18 millimeters, 1.2-2 mm wide.These parasites develop in the second organism - both the owner - the middle and the end.The middle host is mollusk and mas fish, the finals are people.
Together with the stains of infected people and animals, eggs fall into fresh reservoirs, where they swallow mollusks.In the mollusk body, the eggs reach the invasive level - the cervix, the cervix leaves the molluska and introduced into the mas fish body, or entering their organisms when mollusks eat fish.In the Pisces body, the parasite develops into a meter in the cyst, the dimension reaches 0.17-0.21 mm.
When eating, the infected fish is infected by a person, the cyst leaves the meter in his body, they pass from the stomach and intestines to the liver and bile ducts.In these organs, they remain parasites, and after 10-12 days they reach sexual maturity, begin to lay eggs.In the human body, a two-year-old cat can be parasites up to 10-20 years.
Schistosomes
Schistosomes are blood plates.These are separate helminths, reaching 4-20 millimeters long, 0.25 mm wide.The Schistosome body comes with a 2nd suction cup and stomach, they are located near each other.Schistosoma women are longer and thinner than men.There is a longitudinal groove on the man's body, so he holds a woman.Their eggs with a diameter of 0.1 mm, the shape of the oval, on the surface of one of the columns is a large spike.
The human worm schistosomes in the role of the final owner of choosing people, in their organisms they are parasites in small colon veins, abdominal cavities, uterus, bladder.Worms eat blood, partially absorb nutrients through cuticle.Schistosomes are transported to the intestines and bladder, where they cook and stand out with stools or urine.In fresh water, the larvae came out of the egg, the mid -host was mollusk.In the mollusk body, the Meta Ceriacaria develops into 4-8 weeks.
Tapered bull
The cow chain is a parasitic strip that causes adolescent disease.These are large helminths that can grow up to 3-12 meters long.On the parasite body is a small head with a diameter of up to 3 mm, neck, and about 1000 segments.After entering the human body, along with unprocessed thermal meat, the soliter is attached to the intestinal wall with 4 cups of suction.
In the Hermaphrodite segment, eagle eggs are placed, every year one individual lays up to 600 million eggs.Helminths like humans are parasites in the intestines 20 years or more, if there is no timely treatment.
Pork worms
Pork tape worms, such as bulls, on the body have 4 cups of suction, but in addition to this, the helminth body also comes with a double hook hook.Reach two to three meters long.Pork worms have three -doped ovaries, on each side of the uterus with 7 to 12 branches.The feature of this helminth is the ability of the segment to crawl out of the anus.After going out, their shells become dry and broken, so the helminth eggs enter the external environment.The middle master of the tape worm can be a pig and someone.
The main owner is the person.Intestinal parasites in humans include pig worms, helminths is located in the patient's intestines, where he lays the eggs.Infections occur when invasive meat is used.
Echinococcus
The causative agent of echinococcosis reaches 3-5 millimeters long.It is made up of heads, where there are four suction cups and two hook holes, and three segments.The latter of this segment has a advanced reproductive system.The middle host is a livestock or a person, the final owner is a dog, a wolf.Infection occurs as an oral path.
Echinococcus enters the intestine, where the larvae comes out of the egg.With the help of hooks, the larvae penetrates the door vein system, from which, together with blood, they spread into the liver, light, muscle tissue.
Speaker
Tips - round worms, pathogens enterobiosis, a disease mentioned with dirty hands.As far as the infection is subject to children.Infection occurs as a oral method and home relationship.You can find this worm in stools.
Women from the genus Pinworms Helminants reach 5-10 mm long, men-3 millimeters.The body shape for pinworms is white spindle -shaped white.The end of the body in the woman is slightly pointing.Adult worms of parasites in the lower intestine of the small and large intestine, attached to the wall with the help of head vesicles.To lay eggs, the female pinworms enter the rectum, crawl and lay eggs in the anus, then die.The delayed eggs become invasive after 4-6 hours.Life expectancy of pinworms - one - two months.
Soldier
Soldiides are other representatives of circular worms - parasites, ascariasis pathogens.These helminths are yellow - pink, has a long spindle of a metaphorical form, separately.Ascaride women grow up to 20-40 centimeters, men reach 15-25 centimeters long.Every day, an ascarida adult woman lays more than 200 thousand eggs, which, along with human stools, stands out into the external environment, where after 12-14 days they become invasive.
The human body of parasites in the gastrointestinal tract, locally especially in the small intestine.Full development cycle from invasive eggs to maturity takes about 3 months.
Vlashev
Vlasodgov - a round helminths that cause trichocephalosis.Helminants are thin chocolate nematodes with the front of the thin filaments and rounded back.Blazo-head women grow up to 3.5-5.5 centimeters, and men are up to 3-4.5 centimeters.A person's worm larvae is located in the cecum, where they are parasites to puberty, and eggs are also laid there.With large -scale invasion, helminths can also occupy the colon, including the rectum.
Every day, women blazo -head lays 3.5 thousand eggs.Helmint eggs have a adjustable shape, covered with a thick shell, colorless "cover" located on the pole.Eggs fall into the soil together -with the movement of the main owner's intestines, in the presence of good conditions, they can maintain the trarks of up to two years.The duration of parasitation in the human intestine is 5-7 years.
