Related to prepatent period: paratenic host

pre·pa·tent pe·ri·od

in parasitology, the period equivalent to the incubation period of microbial infections; it is biologically different, however, because the parasite is undergoing developmental stages in the host.

prepatent period

A term of waning use for the “silent” period between the time an exogenous agent (specifically, a parasite) impacts on a living organism and its detectability in the new host; e.g., latent period.

pre·pa·tent pe·ri·od

(prē-pā'tĕnt pēr'ē-ŏd)
parasitology The period interval to the incubation period of microbial infections; it varies biologically, however, because the parasite undergoes developmental stages in the host.

prepatent

before it becomes manifest. Used with reference to infection with bacteria, viruses and particularly helminth parasites.

prepatent period
the period between infection of the host and the earliest time at which the causative agent can be recovered from the patient or, in the case of parasites, eggs or larvae can be recovered from feces, urine or blood. It is usually shorter than the incubation period but may be longer in some parasitic infestations, e.g. hookworm infestation in puppies.
