Every year, scientists and doctors conduct disease analysis. According to the latest statistical data, the number of infected with opisthorchiasis exceeds 20 million people, with the majority of patients living in Russia and CIS countries.

Helminth opisthorch penetrates the liver or pancreas, after which it begins its development. Everyone should know the causes of the disease, in order to avoid infection in the future.

People can get infected from animals or fish. In most cases, the worm gets into a person through the meat of the following fish:

  • Bleak;
  • Carp;
  • Yaz;
  • Carp;
  • Zherekh;
  • Bream.

Opisthorchias completes its cycle after penetrating into the human body. People or animals are his last carrier. The worm gets to the new owner only through the mouth, that is, with the meat of a fish or animal. Also, the worm and its eggs can be caught when licking hands or from kitchen appliances, if no heat treatment has been performed.

The life cycle of the opisthorchiasis

Opisthorch chooses as its habitat the pancreas of mammals or fish. In the life of the helminth there should be two intermediate hosts, namely:

  1. Molluscs;
  2. Fish, carp family.

After helminths move to the body of the final host. It all depends on who ate the infected fish.

The cycle of development of opisthorchiasis consists of several stages. Adult helminths lay eggs, which in turn with feces get into the external environment. An obligatory condition, for the existence of a helminth, is a mollusk that lives in shallow, practically dried up reservoirs. They swallow the larvae along with the mud. Once in the body of the carrier, the larva undergoes a series of metamorphoses.

At the next stage of the life cycle, the opisthorch enters the body of carp fish. From the mollusk in the form of a larva - cercaria, which is selected into the water, and then finds carp fish. Having settled in the muscles, the helminth continues to develop. After about 6 months, opisthorchosis completes its incubation period. After that he is able to move into the body of a person or an animal.

It should be noted that fish can leave the habitat of mollusks. If within 2 years people or animals do not become infected with an ailment, then the fish gets rid of helminthic invasion.

The life cycle of a opisthorch depends on which organ it hit. Where opisthores live, many people are interested:

  • Intrahepatic bile water in 60% of cases;
  • In the gallbladder in 30% of cases;
  • In the pancreas in 10% of cases.

Knowing what opisthorchosis is, many people are interested in the question of how many helminths live, if they can not be disposed of? It is best to get rid of the worm, since it can live up to 25 years. In this helminthic invasion can be infected quickly, the cycle of development of the worm is only six months.

Thermal treatment and freezing from opisthorchiasis

Opisthorchiasis is a serious disease that can cause other diseases. It is best to fight it, before the life cycle of the larva will continue in the new carrier.

It should be noted that when contact with the patient, it is impossible to get infected, since for the development of opisthorchiasis, mollusks and fish are needed. To eliminate the causative agent of helminthiosis, the thermal treatment of fish is perfect.

It is enough to know how many opisthores live to prevent their occurrence. During its existence, namely for 20 years, the worm can lay several million eggs and provoke the appearance of serious ailments.

To kill the parasite, it is necessary to properly prepare the fish:

  • Boil the fish for more than 20 minutes after the water boils;
  • To fry, the fish should be divided into several pieces, and then placed in a sufficient amount of fat, fry for at least 20 minutes;
  • For lovers of fish pie, you should know that the oven should be baked for at least 1 hour;
  • Salting is carried out for 2 weeks at a rate of 10 kilograms of fish 2 kilograms of salt;
  • It is strongly advised against using low-salted fish or stroganin, as the possibility of infection remains without heat treatment.

You can fight worms not only by proper cooking. It is necessary to know at what temperature opisthores perish. Since it is better not to expose fish meat to high temperatures, it is possible to use freezing and there will be no trace from the opisthorchiasis.

Opistorhi die under the following conditions:

  • At -40 degrees, it will take 7 hours, before the complete elimination of the worm;
  • Opisthorchias when frozen fish to -35 degrees, will be eradicated after 14 hours;
  • Also opisthorchiasis dies when frozen to -28 degrees, for the complete destruction of worms 32 hours are needed;
  • It should be noted that in conventional household freezers, the helminth will not die.

Knowing at what temperature opisthorchias die, you can not be afraid to consume fish meat. Do not forget that the knife and the cutting board must also be carefully processed, since they can remain larvae.

It is recommended to process the room, as when cutting fish, larvae can get on another kitchen utensils. To destroy the worm, you can use ultraviolet or heat treatment. You can also boil kitchen utensils.

Where does the opisthorch live?

Opisthorchias can cause serious illnesses or complications, it all depends on where the parasite lives. Getting into the liver, the worm forms small wounds on the walls of the organ with the help of its suckers. As a result, infections can occur.

Infectious disease can cause and the helminth itself, because in the course of its life, it releases toxic substances. The patient may develop:

  • Nausea;
  • Diarrhea;
  • Allergic reaction;
  • Inflammation.

Many wonder whether the worm multiplies in the human body and does it cause serious consequences? This should not be feared, since for a full development cycle, helminth needs water and mollusks, so the consequences and complications can only be caused by adult worms.

Depending on where the worms live, the degree of complication changes. If the worms are located in the liver, the patient in most cases appears:

  • Cirrhosis;
  • Purulent processes in the liver;
  • Hepatic failure;
  • Chronic hepatitis;
  • Fatal disease.

Depending on how much the worm lives in the body, various complications can appear. To prevent this, it is necessary after the first signs of helminthic invasion to begin to treat.

It is best to first seek help from a doctor so that he can determine what life cycle the parasite has gone through. After that, you can appoint a treatment. If desired, you can use the recipes of traditional medicine.

A helminthic invasion can cause a lot of problems for a patient, so you should try not to allow the appearance of helminths. Preventive measures are able to interrupt the cycle of development of the opisthorch. It is enough to properly prepare fish and heat cooking utensils, then you can not be afraid of helminthic invasion and consequences.
