Which cestode poses significant public health risks and is capable of infecting dogs?

Echinococcus granulosus is a cestode known for its significant public health implications, particularly as it can lead to echinococcosis in humans. This organism is part of a complex life cycle that primarily involves canines, especially dogs, which serve as definitive hosts. When dogs ingest the eggs of Echinococcus granulosus from contaminated sources, they can shed these eggs in their feces, thereby increasing the risk of human infection. Humans can become infected through ingestion of these eggs, often via contaminated water or food, or through direct contact with infected animals.

This specific cestode is particularly concerning because it can result in the formation of hydatid cysts in humans, leading to severe health complications depending on the organs affected. The potential for zoonotic transmission makes Echinococcus granulosus a priority in both veterinary and public health arenas.

While other cestodes like Dipylidium caninum, Spirometra mansonoides, and Taenia pisiformis may be associated with dogs, their public health impact is not as pronounced. Dipylidium caninum mainly affects children and is often associated with flea infestations without the severe health repercussions that accompany Echinococcus granulosus infections. Spirometra mansonoides and Ta
