Helminthiases are one of the most common diseases between children and adults.In the human body, various types of worms can give up.There is a view away from medicine that helminths only affect the digestive tract, in fact, worms can be parasitated on almost all internal organs - the liver, lungs, heart, brain brain, as well as muscle tissue, subcutaneous tissue.The article refers to what a person has a person.
Classification
There is a huge number of helmets that can hit a person below are the most common of them.Most of the worms belong to any of the 3 teams-travelers, cestodes or nematodes.
Trematodes are a class of parasitic worms of a level of shape, about 40 types of worms that surprise a person is known.The most common:
- cat or Siberian bicarry (causes opisthorchosis).
- Schistosomes (cause slits).
The spots are flat ribbon worms.Cestodes representatives do not have a digestive system.Most of the time a person is surprised:
- Bull tapeworm (causes tusinchosis);
- Pork (causes cysting).
- Echinococcus (causes echinococcus).
The nematodes are round worms, primary crap.Common helminths that influence the person:
- Pinworms?
- Askarides;
- Vlashev.
Worms in humans are symptoms in photography (most Elminths affect the gastrointestinal tract, therefore nausea and vomiting, diarrhea or constipation, intestinal obstruction, weight loss, lack of appetite or excessive hunger):
Koshachi or Siberian Bicarry
Koshachi or Siberian Bicarry - a small parasite of Laulis from a group of liver suckers.The causative agent of opisthorkhoz disease.At the length of the feline bicarry, it reaches 8-18 mm, in width-10.2-2 mm.The parasite is developed in the organizations of the two owners - intermediate and final.The intermediate host is carp and fish, the final is a person.
Along with the feces of infected humans and animals, the eggs fall into fresh tanks, there they are swallowed by the molluscs.In the soft body, the eggs reach the invasive stage - cervical, the cervix leave Molluska and imported into the body of carp fish or enter their organisms when mollusks eat fish.In the body of Pisces, the parasite grows in one meter in cysts, its dimensions reach 0.17-0.21 mm.
When they eat, an infected fish is infected by a person, the cysts leave the meter on his body, pass through the stomach and intestines in the liver and bile ducts.In these organs, they remain parasitized, and after 10-12 days they reach the sexually mature stage, they begin to put eggs.In the human body, the two-year-old cat can resign for up to 10-20 years.
Schistosomes
Schistosomes are blood saucers.It is a level of separate elminths, reaches a length of 4-20 mm, 0.25 mm wide.The body of the slit is equipped with the 2nd suction and abdominal, they are close to each other.Schistosoma females are longer and thinner than males.There is a longitudinal groove in the male body, with him, holds the female.Their eggs with a diameter of 0.1 mm, oval shape, on the surface of one of the poles is a large spike.
The human worms of the slit soil in the role of the final owner choose humans, in their organisms they give up in small colon veins, the abdominal cavity, the uterus, the bladder.The worms feed on blood, partially absorb nutrients through the skin.Schistosomes are transferred to the intestines and the bladder, where they mature and stand out with faeces or urine.In freshwater water, a larva comes out of the eggs, its intermediate host is Mollusk.In Mollusk's body, Meta Ceriacaria grows in 4-8 weeks.
Bull
The bull chain is a strip parasite that causes teeniarinchosis disease.These are huge elmins that can grow up to 3-12 meters in length.In the body of the parasite there is a small head up to 3 mm in diameter, a neck, as well as about 1000 parts.After entering the human body, along with the unprocessed thermally contaminated meat, the selector is attached to the intestinal walls with 4 suction cups.
In the Hermaphrodite sections, elm eggs are placed, a person annually, a person places up to 600 million eggs.Such helminths in humans are parasites in the intestines of 20 years or more if there is no timely treatment.
Pork
The pork film, such as the bull, has 4 suction cups in the body, but in addition, the helminth body is also equipped with a double hook.Reaches two to three meters in length.The pork tape has a three ovarian, on each side the uterus has from 7 to 12 branches.A characteristic feature of this helm is the ability of the sections to crawl out of the anus.After exiting out, their shell becomes dry and exploded, so the elmine eggs enter the outside environment.The filmmaker of the film can be pigs and one person.
The main owner is a person.Intestinal parasites in humans include pork, the elmin are found in the patient's intestines, where he puts his eggs.Infection occurs when invasive meat is used.
Echinococcal
The causative agent of echococcus reaches 3-5 mm.It consists of one head, with four suction cups and two hole holes, and three - four sections.The last of the sections has a developed reproductive system.The intermediate host is animals or person, the final owner is dogs, wolves.Infection appears as an oral path.
Echinococcus enters the intestines, where the larvae come out of the eggs.With the help of the hooks, the larvae penetrate the gate vein system, from which, together with the blood, spread to the liver, light, muscle tissue.
Speakers
Tips - Round worms, enthusiastic pathogens, so - called dirty hand disease.To a greater extent, infection of children is subject to children.The infection appears as oral and the mode of contact.You can find these worms in feces.
Females of the Pentary genus are 5-10 mm in length, male-3 mm.The shape of the body for pinworms is the shaft -shaped milky.The end of the body in females is slightly sharp.Adult worms are parasitized in the lower parts of a person's small and large intestines, connected to the wall with the help of head cysts.In order to put eggs, the females of the pentaries go to the rectum, crawl and put eggs in the anus area and then die.Delayed eggs become invasive after 4-6 hours.The life expectancy of Pinworms - one or two months.
Assarids
Askarides is another representative of the class of round worms - parasites, Askaria pathogens.These helm are yellowish - pink, they have an elongated axis of the virtual shape, separately.Ascarid females are increased to 20-40 cm, males reach 15-25 cm long.Every day, an adult woman Ascarida places more than 200,000 eggs, which, along with human faeces, stand out in the outside environment, where after 12-14 days they become invasive.
The human body is parasitized in the gastrointestinal tract, mainly located in the small intestine.A complete cycle of growth from an invasive egg in a mature stage lasts about 3 months.
Vlasev
Vlasodgov - round elminths that cause trichogalase.Helminants are a thin brown nematody with a thin filamentary forehead and a rounded rear.Blazo-head females rise to 3.5-5.5 cm and males to 3-4.5 cm.A person's worm larvae are located in the Cecum, where they resign at adolescence and the eggs are also placed there.With mass invasion, helminths can also understand the large intestine, including rectum.
Every day, Blazo -head females put 3.5 thousand eggs.Helmint eggs are barrel -shaped, covered with thick brown shell, colorless "lids" in the poles.Eggs fall to the ground along with the movements of the main owner of the main owner, in the presence of favorable conditions, can maintain invasion properties for up to two years.The duration of parasitism in the human intestines is 5-7 years.
