Experts are finding more and more varieties of helminths that are ready to settle in other living organisms and parasitize them.

Bull tapeworm is one of the most dangerous. It lives in the human intestine, despite the fact that its larvae arise and develop in the bodies of representatives of cattle, which is where its name comes from.

The features of the structure of the bullish tapeworm are quite an interesting topic for discussion. This is described in more detail below.

What is this parasite?

To begin with, he is a representative of tapeworms, moreover, of a rather large size. This specimen grows in length from 4 to 10 meters.

The external structure is quite simple: head, neck, body. His entire body consists of about 1000 segments, and he grows throughout his life. New body parts form around the neck.

Scolex - a rounded head, no more than 2 mm, equipped with powerful suction cups. But the hooks inherent in parasites are not observed in the bovine tapeworm, which is why it is also called "unprotected". The structure of the bovine tapeworm allows it to exist for about 20 years in a living organism. That's a pretty decent amount of time for a parasite.

Meals are provided in a slightly non-standard way. The worm attaches itself to its walls in the intestine with the help of suction cups on the scolex and eats food already digested by humans with the help of the entire surface of its long body. This is justified by the lack of a digestive system and the inability to process food on its own.

In addition to the above, there are several points according to which it can be characterized precisely as a parasitic organism:

  1. Strong body covers that save the bovine tapeworm from gastric juice.
  2. Underdeveloped nervous system.
  3. The sense organs are poorly expressed, practically absent.
  4. High level of fertility.

Reproduction and spreading process

Since the bovine tapeworm is a representative of flatworms, it is hermaphrodite, like most of them, therefore, reproduction takes place without the participation of the second individual. Eggs are formed in the segments that make up the entire body of the parasite.

One segment contains one ovary and a large number of testes. The only exceptions are those segments that have recently been reproduced. But eggs cannot ripen everywhere. They appear in the most distant, oldest areas, and come off, coming out during the bowel movement.

Livestock can eat grass on which the eggs of the bovine tapeworm have already settled. Already being in the body, with further ingestion into the stomach, the larvae of the parasite, imperceptible to the eye, hatch from the swallowed eggs.

In the process of growth, the larvae are transformed into the so-called finns - a small bubble, no larger than a pea, in which the head of the parasite with a neck that has not yet grown is located.

If the meat of an infected animal, when eaten, has not undergone sufficient heat treatment, i.e. was poorly fried or boiled, then the helminths retain their life and the process of their development from a certain point occurs already in the human body. This is why so many beloved steaks with blood are so dangerous.

Why is it dangerous for a bovine tapeworm to enter the human body?

This helminth, penetrating the intestines, causes a disease such as teniarinhoses. The characteristic that helps to determine the presence of this parasite in the body is not much different from the symptoms of the presence of other parasites.

  1. General weakness in the body.
  2. Frequent headaches.
  3. Fast fatiguability.
  4. Nausea followed by vomiting.
  5. Bulimia, in especially severe forms.
  6. Abdominal pain.
  7. The most obvious symptom is the independent detection of worm eggs in the feces.

The disease itself is a rather life-threatening consequence. The most terrible of them is tissue necrosis or perforation of the pancreas. They can occur with the advanced development of the disease.

Acute form of cholecystitis. In addition, a long delay in treatment can lead to appendicitis, abscesses and inflammation of various organs.

Diagnosis of the disease is a very laborious process if the parasites are in the larval stage. There is no detailed characteristic that can unconditionally determine the presence of helminths.

At a low acidity level, the test for parasites is considered positive. Also, the doctor prescribes a specific diet, with predominant products that do not form toxins. Plus, meals should be split into several meals per day. The minimum number is 5 times.
