Tapeworm symptoms9/22/2023 Human feces -> meat from infected pigs or cows -> intestine Symptoms of a tapeworm infection Finally, humans ingest these meats infected with juvenile worms, and one of them develops as an adult in the intestinal tract, closing the cycle.Then, pigs and cows can accidentally consume these eggs and, over time, the larval forms settle in the tissues of the animals, leading to cysticercosis.In the first place, an infected human expels eggs or segments of the adult tapeworm in their feces, releasing them to the ground, where they can remain for up to months.To simplify their complex life cycle, we can summarize the steps in three main ones. It’s important to emphasize that humans are the only definitive host for this parasite, unlike many other diseases transmitted from animals to people. A species of Asian origin, Taenia asiatica.Learn more: 5 Tips to Eliminate Intestinal Parasites A complex cycleĪccording to the Centers for Disease Control and Prevention (CDC), the human tapeworm is caused by three species: In their head or scolex, they have a series of hooks, which allow them to attach their oral apparatus to the patient’s intestinal walls and feed on the food that passes through it. In their adult form, tapeworms are shaped like clearly segmented and flattened worms. The larval and juvenile forms produce cysticercosis, an even more serious condition that occurs when these are located in various organs and tissues of the affected person.Adult tapeworms produce taeniasis when they lodge in the intestine of the final host.They have a complex life cycle and, depending on the stage causing the condition, two diseases can occur in the affected individual. They’re extracellular endoparasites since they live inside their host, but they don’t work at the cellular level, as is the case with viruses. Taenia is a genus of parasitic flatworms in the cestodes class. How does infection happen? What are the types of tapeworms that infect humans? These and other questions may arise when talking about this parasite.īelow, we’ll take a closer look at the most relevant aspects of this parasite. According to information published by the World Health Organization (WHO), taeniasis (the medical name for this parasitic disease) causes digestive discomfort and neurological complications in the most severe cases. Tapeworm intestinal infection is common among people who eat undercooked beef or pork.
