The pig is the main source of meat for humans. Unfortunately, these pets have relatively weak immunity, especially if they live in large herds on farms or enterprises. Due to the fact that they live in tight conditions and sometimes lack the necessary vitamins, they can pick up various diseases. The most common of these is pig cysticercosis.

Pig cysticercosis
General description of the disease
Pig cysticercosis is a disease that is caused by the cysticercus cellulosae that they This is related to the larval stage of Taenia solium pork tapeworm. Unfortunately, this disease affects not only pigs, it is also transmitted to cats, dogs and humans.
Most often, pig cysticercosis is based in the heart. human larvae live in the eyes and brain. It is necessary to constantly vaccinate so that cysticercosis does not appear in pigs and a person, as a result, cannot become infected.
What can become a causative agent
Pig cysticercosis, or rather staple strobile, usually 1 to 3 m long. Such a scolex has 2 bases of hooks (23-33). Typically, as a part of the strobilus, there are about 900 segments. All have a slightly oblong shape. The width of the stick is 2 times greater than the length, but when it begins to “grow”, everything changes the other way around.
The genital openings of such parasites are constantly moving. The main characteristics of cysticercosis in pigs are:
- possible armed scolex;
- three-lobed ovary;
- especially a small number of extraneous branches in the uterus of the mature joint (8 -13) .
Any segment that is already considered an adult consists of 50 thousand eggs. Typically, the eggs have the shape of a circle, small, gray in color, are in a very fragile and delicate shell, which can easily die when outside of a living organism. Similar oncospheres have 3 components of embryonic hooks, which in turn can reach 0.02-0.03 mm in length and 0.03 in width. Cellulosae is a kind of transparent ball that has the shape of a circle, its size can be compared with a small pea or bean. Finnos can cause a tapeworm reaction.
Life expectancy
Pig cysticercosis develops only if there are definite hosts, in our case it is a person and intermediate creatures are pigs. In any case, the human body is the carrier of the cysticerci with discharge into the external environment. After a great destruction, they all break up and free, that is, they cling to the animals. Pigs themselves are very sensitive to coprophagy: they can eat the remains of human excrement along with the eggs and segments of the cysticercus, thereby becoming infected with cysticercosis.
Cysticercus in the body of medium carriers can live for 2-4 months.The carrier – a person – is initially infected with theoniosis. Usually this happens when a person eats raw pork meat that was infected with cysticerci, or meat that was poorly cooked.
In the body, tapeworm becomes “adult” only at the age of 2-3 months. Prior to this, parasites live and develop in the intestine, the ability to understand that they are there is minimal. In the same way with animals. They develop very slowly and imperceptibly.
You may notice slight changes in the behavior of the animal. It can often “ride” on the priest, bite itself there, start eating a lot and sometimes introduce itself strangely.
General data of epizootology
The main source of infection in pig cysticercosis is a person who in turn is sick with teniosis. Teniosis at the stage of maturation “leaves” the person and scatters his ovaries everywhere. Thus, a pig who does not have an immune system against such cysticerci immediately picks them up. This is all due to the fact that the pigsties are not clean, they neglect all the rules of hygiene.
These chains have a very stable immune system, they can survive even in the worst living conditions. It is because of this that they can infect almost the entire flock in a few days. Tapeworm eggs can survive and be active, even if they are completely dried. In this position, they can live for several months.If they are kept in a chlorine solution with a tincture percentage of 10-15, then they can live only 5-6 hours. In the photo you can see how they look under the microscope.
How does the disease appear
A very painful condition manifests itself in the animal when it begins to “immigrate” all the larvae from the intestine to the main location. This all leads to the fact that the decay of tissue cells begins, inoculation of all microbes in the body. In addition, worms poison all organ systems and all food that enters the intestines, resulting in an allergy.
In pigs, cysticercosis often manifests itself through allergies or constant vomiting of an abnormal color. An allergy can manifest itself through a profuse rash, large sores, sneezing, or coughing. If vomiting is green or white, then the parasites have already spread throughout the body and begin to settle in all possible places. The main irritants of this ailment are pig finnose and tenuicol cysticercosis.
Possible clinical signs
As mentioned earlier, it is very difficult to understand whether a pig has cysticercosis or not. Often the disease proceeds calmly and without symptoms. Of course, the animal feels that something is wrong, but usually does not react to it at all.
If the percentage of infection in the animal is very high, that is, the parasites have already filled the entire body, then the pig can breathe heavily, because due to a noticeable deterioration in blood circulation, temporary edema and convulsions may appear.
This disease can lead to the death of the animal if it is too late.Usually this happens when the parasites have completely filled the heart of the animal and methodically take their whole life out of it. On the Internet you can find a photo of what an infected heart looks like.
Changes
In those locations where parasites live, you can often notice dystrophy and atrophy of muscle fibers, they also break muscles that are interconnected by tissues. In addition, often there are branchless larvae, the other name of which is Finns.
It is almost impossible to make an accurate diagnosis to a living organism. The examination may use allergic and serological tests. Under production conditions, the animal is diagnosed immediately after its death.
This happens as follows: the animal is cut and they begin to be carefully examined. The first things that are checked are the chewing muscles and the muscles of the belt. After that, they examine the most important organ – the heart, then the tongue, liver, etc.
Preventive measures
The first and most important thing is to clean all the places of detention cattle. Continuous vaccination of the animal is also incredibly important, especially if it is kept for slaughter. In addition, after slaughter, all meat must undergo a thorough examination of all instances. Today, the law categorically prohibits the sale of animal carcasses if they have not been examined by a specialist, since the parasite egg can live for several months.
Only carcasses with a tag can be given for slaughter: this means that the animal was healthy.Cysticercosis is a very unpleasant disease, the main distributor of which is a person. Unfortunately, it is possible to understand whether there is a parasite in the body of a mumps only after the death of the animal. In order to be prepared for all the surprises associated with livestock disease, it is extremely important to familiarize yourself with the content of the article “Cellulose cysticercosis in pigs”: this will allow for the correct prevention.
