Driven by the pathogen of the dog tapewormThe dog tapeworm is the most dangerous and at worst can even lead to death if there is no quick treatment.

A tapeworm is a parasite of mammals as host uses are not self-fed to them by the intestine. The dog tapeworm is one of the most dangerous tapeworms. It is a small parasite that grows in the small intestine of dogs, sheep, horses and humans in order to carry out its development from fertilized egg to larva. The man acts in this case as an intermediate host.

The tapeworm has a dangerous pathogen for humans, which may have an infection even in life-threatening consequences. The pathogen is known as Echinococcus granulosus. It occurs worldwide phenomenon is found mainly in Europe but around the Mediterranean. The final host is the dog.

Course of infection

An animal is infected with the parasite; it separates the feces the eggs from the small tapeworms. These can then become infected via contaminated food, the consumption of raw meat, or other fruits of forest animals or humans. In the intestine of the new intermediate host to move to the small eggs which develop from larvae; that can settle on the blood vessels in the internal organs. They penetrate the intestinal wall. Mostly affected is 60 to 70 percent of the liver, but can also brain, lung, bone, spine, bile ducts, kidneys, muscles are affected.

Diagnosis and symptoms of infection

The incubation period after infection is six months to several years is very long, the first symptoms occur accordingly to late. The diagnosis is often an incidental finding. The pathogen forms cysts of considerable size in the affected organs. The fluid-filled cavities cause pain or a feeling of pressure in the upper abdomen. Also, difficulty breathing or coughing, muscle pain and head pressure can be differentiated according to the localization sequence. The cysts grow into other tissue structures adjacent organs or tissues infected with the appropriate conditions such as intestinal obstruction or functional tasks displace various glands. The diagnosis of cysts is by ultrasound or computer tomography. The agents themselves will be demonstrated over a stool test in the laboratory.


The complaints require rapid treatment. Remains of the pathogens in the body, it is because of its small size of three to six millimeters more larvae. The liver and other organs affected by the cysts are broken and literally put their function following after another. The infection with the pathogen of the dog tapeworm can result in the worst case, even death. Therefore, the cysts are removed surgically. This may not be violated during the procedure, as this will result in a further expansion of the parasite to other organs. Cysts or affected tissue, which can not be removed surgically, are treated with chemotherapy in general. Here, the stage of disease determines the duration of drug therapy from six weeks to several months. Most larvae are not killed all the parasites, the treatment must often be repeated or continued for life. Seven percent of patients die despite treatment.
