Helminthias are one of the most common diseases in children and adults.In the human body, different types of worms can parasitize.There is a thought away from medicines that poisons affect only the digestive tract, in fact, worms can be parasitized in almost all internal organs - the liver, lungs, heart, brain, as well as muscle tissue, subcutaneous tissue and eye.The article refers to what has worms a person has.
ClaSSIFICaTION
There are a large number of poisons that can hit a person, below are the most common of them.Most worms belong to any of the 3 groups-trees, cestodes or nematodes.
Trematodes are a class of parasitic worms of a flat shape, about 40 species of worms that amazed a person is known.The most common:
- Cat or Siberian bicarry (causes opisthorchosis);
- Schistosomes (causes skistosomosis).
Cestodes are flat striped worms.Cestodes representatives do not have a digestive system.Most often, a person is amazed:
- Tapeworm (causes tanningosis);
- Pork seating (causes cystistosis);
- Echinococcus (causes ecinococcosis).
Nematodes are round worms, primary shit.Common Helmins affecting the person:
- pinworms;
- Ascarides;
- Vlashev.
Worms in humans are symptoms in the picture (most poisons affect the gastrointestinal tract, hence vomiting and vomiting, diarrhea or constipation, intestinal obstruction, loss of shameless weight, lack of appetite or excessive hunger):
Koshachi or Siberian Bicarry
Koshachi or Siberian Bicarry - a small laundry parasite from a group of liver suckers.The causative agent of opisthorkhoz disease.In the length of the cat bicarry, reaches 8-18 millimeters, in width-1.2-2 mm.The parasite takes place in the organisms of the two owners - intermediate and final.The intermediate host is molluscs and carp fish, the final is a person.
Along with feces of infected humans and animals, the eggs fall into fresh tanks, there swallowing molluscs.In the mollusk body, the eggs reach the invasive phase - the cervix, the cervix leave the mollusks and insert into the body of the carp fish, or enter their organisms when molluscs are eating fish.In the body of Pisces, the parasite develops in one meter in cysts, its dimensions reach 0.17-0.21 mm.
When eating, an infected fish is infected by a person, the cysts leave the meter in his body, they pass from the stomach and intestines to the liver and bile ducts.In these organs, they remain parasitized and after 10-12 days they reach the mature sexual phase, start laying eggs.In the human body, the two-year-old of a cat can parasitize up to 10-20 years.
Skistosoma
Skistosomes are blood dishes.This is a special flat helminth, reaches 4-20 millimeters, 0.25 mm in width.The skistozy body is equipped with 2nd glasses of suction and abdominal, they are located close to each other.Schistosoma females are longer and thinner than men.There is a longitudinal habit in the male body, with her, he holds the female.Their eggs with a diameter of 0.1 mm, oval shape, on the surface of one of the poles are a big stroke.
Human skistosomes in the role of the last owner choose people, in their organisms they parasitize in the small veins of the colon, abdominal cavity, uterus, bladder.Worms feed on blood, partially absorb nutrients through the cuticle.Schistosomes are transported to the intestine and bladder, where they mature and come up with feces or urine.In freshwater waters, a larva comes out of the eggs, its intermediate host is mollusc.In the body of Mollusk, Meta Ceriacaria develops in the curial at 4-8 weeks.
lazy
The bull chain is a striped parasite that causes a adolescent disease.These are the large poisons that can grow up to 3-12 meters in length.In the parasite body is a small head up to 3 mm in diameter, a neck, and about 1000 segments.After entering the human body, along with thermally infected raw meat, the soloity is attached to the intestinal wall with 4 suction cups.
In the hermaphrodite segments, the helminth eggs are laid, every year an individual lays up to 600 million eggs.Such helminths in humans are parasite in the intestines 20 years or more, if there is no timely treatment.
Pork
Pork Tapeworm, like Taurus, has 4 suction cups in the body, but in addition, the Helminth body is also equipped with a double whip of hooks.Reaches two to three meters in length.Pork Tapeworm has a three -goal ovary, on each side of the uterus there are 7 to 12 branches.A characteristic feature of this helminth is the ability of segments to be dragged by the anus.After going to the outside, their shell becomes dry and explodes, so the helminth eggs enter the outer environment.The intermediate cork master can be pigs and a person.
The main owner is a person.Intestinal parasites in humans include pork cork, helminths are located in the patient's intestines, where he lays his eggs.The infection occurs when using invasive meat.
echo
The causative agent of echinococcosis 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 livestock or a person, the last owner is dog, wolves.The infection occurs as an oral road.
Echinococcus enters the intestine, where the larvae come out of the eggs.With the help of hooks, the larvae penetrate the gate vein system, from where, along with the blood, they spread to the liver, light, muscle tissue.
speaker
Tips - round worms, pathogens of enterobiosis, so -called dirty hands.To a greater extent, infection of children is subjected to children.The infection occurs as an oral and contact.You can find these worms in the feces.
Pinworms Helminants females reach 5-10 mm in length, male-3 millimeters.The body shape for pinworms worms is white of finger -shaped milk.The end of the body in women is slightly pronounced.Adult worms parasitize in the lower parts of a person's small and large intestines, attaching the wall with the help of scalp.In order to lay eggs, females of the pinworms worms go to the rectum, crawl and lay eggs in the anus area, then die.Delayed eggs become invading after 4-6 hours.Life expectancy of worms - one - two months.
Ascarids
Ascarides are another representative of the class of round worms - parasites, pathogens of ascariasis.These helminth are yellow - pink, have an elongated figurative finger, separately.Ascarid females grow to 20-40 centimeters, males reach a length of 15-25 centimeters.Day every day, an adult ascarida female raises more than 200,000 eggs, which, together with the human feces, stay in the outside environment, where after 12-14 days they become invading.
The human body is parasitized in the gastrointestinal tract, located mainly in the small intestine.A full cycle of development from an invading egg to a mature phase lasts about 3 months.
Vlashev
Vlasodgov - round helminths that cause trichocephalosis.Helminants are a thin brown nematode with a thin front philamented money and the back rounded end.Blazo heads grow up to 3.5-5.5 centimeters, and males up to 3-4.5 centimeters.A person's worms larvae are located in Cekum, where they are parasitized in the puberty phase, and the eggs are also laid there.With massive occupation, helminths can also invade the Great intestine, including the rectum.
Every day, Blazo -Head females laid 3.5 thousand eggs.Helmina eggs have a barrel shaped shape, covered with a thick brown shell, the colorless "lids" are located in the rod.Eggs fall to the ground along with the intestinal movements of the main owner, in the presence of favorable conditions, they can maintain the occupation properties for up to two years.The duration of parasitizing in the human intestines is 5-7 years.
