| prepatent period | <microbiology> The period of time equivalent to the incubation period of parasite infections compared with microbial infections. It is biologically different, because the parasite is undergoing developmental stages in the host, and the prepatent period represents the time from infection until a female starts to produce eggs, and is equivalent to the latent period in microparasitic infections.
