The human body serves as a favorable environment for the development of not only beneficial bacteria, but also harmful parasites. The largest group is helminths. It can be both ordinary worms located in local organs, and tapeworm tapeworm. What a tapeworm is, how dangerous it is and when you can become infected with a parasite are questions that should be analyzed in more detail.
Why is tapeworm dangerous for humans?
The tapeworm in a person does not make itself felt for a very long time. The host lives for years, not realizing that a huge tapeworm is developing inside, posing a great threat to life. Analyzes for echinococcus are not always informative, repeated sampling causes harm to the body, and if a puncture is performed, there is a high risk of spreading the eggs of the parasite to other organs and tissues. Modern diagnostic tools are still not able to conduct a safe analysis - this is one of the threats to the health of the wearer.
What else is tapeworm dangerous for humans:
- Having settled in the lungs of a person, the larvae provoke coughing and hemoptysis, shortness of breath, pain, difficulty in breathing.
- Forming cysts in the bronchi, the parasite causes suffocation, allergies with concomitant cyanosis.
- A seliteworm in the host's liver causes jaundice. Finna grows to an incredibly large size, and when it collapses, it can be fatal. The location of the worm in the liver causes constant pain, loss of strength.
- Damaging the stomach, intestines, the worm poisons the body. High production of toxic waste products provokes disruption of the gastrointestinal tract, ulcers.
- Cysticercosis is a dangerous disease caused by the larvae of the parasite. Cysticercus affects bone tissue, articular, muscle groups, brain tissue and organs of vision.
How does the infection take place?
Plasmodium malaria symptoms and what it is
The main pathogenic factor is direct interaction with the pathogen. Tapeworms in humans appear due to:
- Insufficiently thermally processed meat and fish;
- Unwashed vegetables, fruits;
- Drinking contaminated water;
- Lack of hand hygiene before meals, after walking.
Very often tapeworm is detected in a person who has his own land plot or farm. With animal-type fertilizers, the larvae of the worms get on the skin, into the room - the slightest chance is enough for this parasite to move into the stomach, intestines of the carrier.
Types of tapeworms
Before you know if a tapeworm lives in the host's body, you should know what a tapeworm looks like and what types of parasite are found in our latitudes. The photo of the parasite gives a visual representation of the worm.
And to the question - is tapeworm dangerous for the host, the answer is yes! The worm in nature occurs in various species, which is due to the intermediate host: fish, domestic animal, pig, cattle. Worms (tapeworm) differ in the following types:
The structure of human lice: types and symptoms of infection
- Bovine tapeworm. Chooses an intermediate carrier of cattle, attaches to the intestine with suction cups, where it develops. It gets to humans through eating contaminated meat.
- Pork tapeworm. The intermediate carrier, the pig, lives in the intestine, attached with hooks. The larvae quickly spread throughout the pig's body, so it is forbidden to eat not only meat, but also lard and offal. It is difficult to remove a tapeworm from a pig; it is almost impossible to defeat a pork tapeworm in a person.
- Tape parasites enter the host's body with raw fish. They are successfully treated, cause few complications, but can cause re-invasion.
- Dwarf tapeworm lives in pets: cats, rodents, dogs. Transmitted to humans, the dwarf tapeworm is a worm that behaves unpredictably, "responding" in the digestive organs and other parts of the body.
- Dog worm. Infection occurs from the feces of street animals. Like pork tapeworm, dog worm is very difficult to remove from the human body.
Symptoms of tapeworm infection
The clinical picture and signs of the disease depend on the localization of the parasite. It is extremely difficult to recognize an invasion at the initial stage of infection. If the eggs of the parasite penetrate the organs from the main habitat, the larvae provoke the formation of cysts. In this case, the invasion looks like this:
- Diffuse cysts disrupt the work of internal organs, including the brain. All this provokes the accumulation of cerebrospinal fluid, causing convulsions, high blood pressure, epilepsy.
- Allergic skin rashes, anaphylactic shock.
- Persistent bacterial infections due to the penetration of harmful microorganisms into the tissues affected by the worm.
- Feverish states are the consequences of inflammation in the foci of cyst formation.
A parasite that lodges in the intestines, symptoms:
- Nausea, gastrointestinal disorders;
- Pain in the lower abdomen;
- Stool instability;
- Chronic fatigue, malaise;
- Weight loss with normal appetite;
- High levels of eosinophils in the blood;
- Bad breath;
- Heart rhythm disturbances, tachycardia;
- Blanching of the skin;
- Bruising under the eyes;
- Sometimes it is possible to visually identify the dead segments in the feces of the host.
If the tapeworm grows large, it completely blocks the absorption of nutrients in the intestines, leading to inflammation of the mucous membrane. During the cycle, adults release a lot of toxins. This causes bowel disease, obstruction, and nerve problems (neurotoxins quickly enter the bloodstream).
