Description of Taenia pathogens
Human tapeworms of the genus Taenia include three species: T. solium, T. saginata, and T. asiatica (T. saginata asiatica). Infection with the adult form causes a disease known as taeniasis (tapeworm infection) in humans. Infection with the larval form, on the other hand, leads to cysticercosis.
Taeniasis/cysticercosis in humans is an important public health problem, especially in developing countries. The disease is caused by the consumption of cysts present in raw or undercooked infected meat. After ingestion, the cyst reaches the human intestine, where it develops into a tapeworm. The mature tapeworm then releases proglottids filled with eggs, which are excreted in the stool. Consumption of these eggs by intermediate hosts causes cysts to develop in soft tissues. This, in turn, leads to the development of cysticercosis. Cysticercosis affects pigs (T. solium) and cattle (T. saginata), causing economic losses.
Unlike T. saginata eggs, T. solium eggs are capable of infecting not only animal intermediate hosts, but also humans, causing cysticercosis in humans. In humans, the larval stage is often located in the central nervous system. It then causes a clinical disorder known as neurocysticercosis, which is the main cause of seizures and epilepsy in most developing countries. Cysticercosis in humans is highly endemic in Latin America, Asia, and Africa.
Tapeworms (taeniasis) occur globally, with an estimated 50-100 million people infected. The most common are T. saginata and T. solium, transmitted through raw or undercooked animal meat. In Poland, cases are relatively few (approximately 200 per year). T. saginata accounts for 90% of cases. The disease is declining in developed countries, but it remains a problem in Africa, Asia, and Latin America.
