Question

Quizplus · Accepted Answer

Sterilizing immunity refers to immunity that completely eliminates the parasite from the host's body. In this scenario, the patient developed immunity and was ultimately cured, indicating that the immune response completely eliminated the parasite. This type of interaction is not symbiotic or commensalistic, as the parasite caused disease in the host. Concomitant immunity refers to immunity that develops in response to a second infection while the host is still infected with the first infection, which is not the case in this scenario.
