Host-parasite interactions

Host-parasite interactions involve a relationship where a parasite lives on or inside a host organism, deriving benefits like nutrients at the host’s expense. The parasite often reproduces within the host, potentially causing harm, such as illness or weakened health. The host's immune system may respond to defend itself, leading to a dynamic battle. These interactions are complex, influencing evolution of both parasites and hosts. Understanding this relationship helps in controlling diseases and developing treatments, as the balance between parasite survival and host health is delicate and crucial for ecological stability.
