The disease has a chronic stage. Uses cows and other cattle as intermediate hosts. Man is the final habitat of the parasite.

The life cycle of a bovine tapeworm is about 20 years. Around the world, according to official data, about 40 ml of people with this disease are registered. The highest level of infected people is in Africa, South America, Asia, Armenia, Azerbaijan. In Russia, mainly the Altai Territory, Perm, Krasnoyarsk, the Republic of MariEl, Krasnodar and the Novosibirsk Region.

In all other areas, the incidence rate is low. The parasite causes teniarinchiasis, an infection that is caused by the disrupted work of the digestive tract and a tendency to a protracted course of the disease.

The structure of the bovine tapeworm is similar to other helminths. It has a head, segments, a neck, but does not contain hooks, therefore it is called unarmed. The cystode is hermaphrodite, that is, it reproduces perfectly by itself. She does not need a partner of the opposite sex for this.

The developmental cycle of the bovine tapeworm is rather primitive; it enters the human body through insufficient heat treatment of meat products. In the human body, the tapeworm goes through two main stages in the development of the bovine tapeworm, which will be discussed in the article.

How does biohelminth enter the body?


Having penetrated the body of livestock, the oncosphere of the bovine parasite tapeworm, in a simple way, is freed from the shell and penetrates through the intestinal wall, moving along the muscles. The transformed embryos already become cysticerci, this stage takes 4 months. Localization of cysticercus is also possible in the brain of cattle.

The vital activity of cystodes is about 6 or 9 months, then they die. Only in the human body do Finns develop into adults, namely tapeworms. Having eaten poorly fried or raw meat, the larvae pass into the stomach. Their membrane is eaten away by gastric juices and acids, which facilitates release and free movement.

They are attached with suction cups to the walls of the abdominal cavity and begin to actively develop. After 3 months, the length of the worm increases to 5 mm. There are cases when nematodes grew up to 10 m, which already threatened the life of its carrier.

When fertile, proglottids are formed, when they mature, they reproduce again. It turns out that the cycle of life is constantly restarted. A huge long pathogen arises from the gathered together proglottids. So the bull tapeworm is rightfully considered the longest of the tape class. It looks like a white flat ribbon.

Signs of teniarinchosis


There are only two forms, initial and chronic. In the initial period, the patient, as mentioned earlier, does not always detect in himself all of the above signals of infection. The formation of individuals leads to allergic reactions. They appear due to the release of biohelminth metabolism products.

From this comes catarrhal inflammation. Acting on the tract in two ways, physical and the production of toxins, the worm sucks out all the nutrients and trace elements.

Intestinal enzymes are blocked by antibodies from the microbe. A person may notice they are infected when they go to the toilet. Larvae are visible in feces, adult nematodes crawl along the thighs, creating a tickling sensation.

During the last phase, there are only 4 main combinations of symptoms from the nervous system, digestive, decreased appetite and stomach pain.



The first phase is almost invisible, it is impossible to recognize it without research. To begin with, the patient is given a short survey for information about eating meat. Coprological examination of materials, clinical blood test and radiography.

When examining feces, a specialist looks for the presence of helminths. Blood donation is needed for information about anemia, leukopenia and eosinophilia. Leukopenia is a decreased white blood cell count, while eosinophilia is an increased blood cell volume. All healthy people have them, but only in small quantities. An x-ray will show ascaris in the respiratory system.

After taking a special solution, accumulations of worms in the form of white stripes will be visible in the picture. Difficulty arises if the tape coexist in the body along with the pork tapeworm. They almost do not differ in structure, but they require different treatment.

The bovine cysticercus will be more harmless, since the cysticercus of the porcine penetrate into the central nervous system, eyes, and other organs. Over time, they develop into subcutaneous cysts.



When a parasite is found, the doctor will prescribe special drugs that block the life of the ascaris and remove them during natural emptying.

In addition, you need to adhere to a diet, exclude fatty, fried foods from the diet. Smoked meats, pickles, cereals, some fruits, alcohol are also prohibited. They are widely used in the treatment of Fenasal, Biltricid.

Fenasal is prescribed in 2 grams for adults. First, after dinner, the patient is given 0.5 teaspoon of soda to drink, and then after 10 minutes the medicine is stirred and drunk. You can take soda and funds in the morning before meals. No laxative is prescribed.

Biltricide is convenient because it is used once. Produced in liquid form, it blocks larvae and worms and removes them along with feces. It is not forbidden to take a laxative with the medicine.

After treatment, it is necessary to pass tests for effectiveness. Often, in order to completely exclude relapse and residual traces of the parasite, the delivery of materials is required within three months.

Prevention measures


Any disease is better prevented than cured. To prevent this from happening, livestock breeders need to purchase feed only from trusted suppliers. Poor quality compound feed is susceptible to the presence of eggs.

Buyers check every piece of tenderloin for Finns before eating. Carry out a thorough heat treatment. You should cook food for at least 1 hour at 80 degrees, or cook for 2 hours.

Prolonged freezing for 5 days at 100 degrees kills the invasion. Freezing for pig infestation is ineffective. You need to buy the meat that has passed veterinary control. If it has an unpleasant odor, it is better to discard the color.
