This worm is a helminth (parasite) that lives in the human small intestine. But the maturation of this parasite begins with the larva of the bovine tapeworm, which we will get acquainted with today. Consider who is the intermediate owner of the bovine tapeworm, its development and class.

What is a bovine tapeworm larva?

This parasite infects wild animals and livestock, mainly cows, buffaloes, deer or yaks. The larva enters their body through contaminated water, grass, hay, parasitizing the organs of its host. The meat that a person can observe on store shelves may well contain bovine tapeworm larvae. Fortunately, they are not difficult to detect, they are yellowish or white balls. May be inside or outside meat.

Tapeworm larvae live all over the world, especially in countries with developed cattle breeding. The rural population is most susceptible to infection, especially people who eat raw or jerky meat, poorly cleaned cow meat. According to statistics, mostly adults suffer from the disease. There are more men infected with tapeworm larvae than women; among children, the number of patients is less.

Bovine tapeworm class and characteristics

What class does the tapeworm belong to? This large worm is a hermaphrodite and belongs to the class of tapeworms of the Teniida family. The size of a bovine worm is more than ten meters. In cattle it lives as a larva, in humans as a tapeworm.

The female and male sexual function is well developed. The eggs are hatched inside a closed uterus. The more eggs, the more the uterus becomes distended. The eggs themselves are round or oval in shape in a thin shell, in its center is the embryo.

The worm has four suction cups on its head - these are the organs of movement of the bovine tapeworm, with which it is held on the walls of the intestine, moving further or backward.

The segments of the worm enter the external environment with the feces of a person, and he himself will not become shorter, growing more and more new segments. When they mature, they move to the tail of the parasite and detach. Its main owner is man (the intermediate owner of the bovine tapeworm is cattle). In the external environment, the infected one releases the eggs of the parasite after 3-4 months, and this process is quite long, fifteen years or more.

The development of bovine tapeworm starting from the egg

The life cycle of the tapeworm starts from the larva and changes its first host to another.

What animal is the intermediate host of the bovine tapeworm? The answer is the picture above, yes, it's cattle. It is only a temporary shelter of the parasite; a person becomes its constant carrier. But not only domestic animals are able to carry tapeworm larvae, but also wild ones: deer, wild boars, buffaloes.

The parasite lives in the human body for twenty years, and the carrier becomes its carrier, secreting eggs into the external environment during feces. Going outside, the eggs pass into earthen soil, water and grass. Outside the host, the eggs survive for a maximum of a month and die if they do not have time to find a living organism.

We turn to the development of the tapeworm. Cattle, or rather its large representatives, drink water, eat grass and hay, in which the larvae of bovine tapeworm are located, and in this way become infected. Once in the stomach and intestines, the larvae are carried throughout the body with the blood stream. Muscle tissues serve as a refuge, there may also be a tongue or heart, and there they mature. After four months, the larvae develop into Finns bovine tapeworm. They live in the body of livestock for about one to three years.

People buy low-quality beef, which contains Finns (larvae) and after eating such meat, they launch the parasite into their stomach, and from there it enters the intestines. Gastric juice frees the head of the larva from the Finns, and it attaches to the intestinal walls, gradually starting to grow. After 2-3 months, an adult tapeworm is formed.
