Which common parasite is primarily transmitted through ingestion of contaminated soil or feces?

Hookworms are primarily transmitted through the ingestion of contaminated soil or feces, which is a key characteristic of their life cycle. These parasites are larval forms found in the environment, particularly in areas where infected animals have defecated. When a host, such as a dog or cat, ingests soil that contains hookworm larvae, infection can occur.

While other parasites also have different transmission routes, hookworms are distinctly recognized for their environmental transmission through fecal contamination. The ability of hookworm larvae to penetrate the skin directly can also play a role in their lifecycle, but ingestion remains a primary means of transmission for many animals, especially in environments where hygiene may be compromised.

Understanding hookworm transmission is crucial for implementing effective control measures, like deworming and managing the sanitation of pet living areas to reduce contamination and protect both animal and human health.
