| 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.

| salina period | <geology> The period in which the American Upper Silurian system, containing the brine-producing rocks of central new York, was formed. Origin: So called from Salina, a town in New York. Source: Websters Dictionary (01 Mar 1998) |
| prodromal period | The time during which a disease process has begun but is not yet clinically manifest. (05 Mar 2000) |
| puerperal period | The period elapsing between the termination of labour and the return of the generative tract to its normal condition; the 6 weeks following the completion of labour. (05 Mar 2000) |
| pulse period | The reciprocal of the repetition rate; e.g., the interval between leading edges of successive pulses. (05 Mar 2000) |
| silent period | The time during which there is no electrical activity in a muscle following its rapid unloading, any pause in an otherwise continuous series of electrophysiologic events. (05 Mar 2000) |
| niagara period | <geology> A subdivision or the American Upper Silurian system, embracing the Medina, Clinton, and Niagara epoch. The rocks of the Niagara epoch, mostly limestones, are extensively distributed, and at Niagara Falls consist of about eighty feet of shale supporting a greater thickness of limestone, which is gradually undermined by the removal of the shale.

| incubation period | <microbiology> The time from the moment of inoculation (exposure) to the development of the clinical manifestations of a particular infectious disease. (13 Nov 1997) |
| quarantine period | The time during which an infected individual or an area is kept isolated, avoiding contact with uninfected individuals; can be any specified period of time, varying with the disease in question. The term is derived from the Italian word for forty, since the period of isolation of individuals suspected of plague in the Middle Ages was forty days. (05 Mar 2000) |
| induction period | The period required for a specific agent to produce a disease; the interval from the causal action of a factor to initiation of disease, e.g., the interval between exposure to radiation and the onset of leukaemia; the interval between an initial injection of antigen and the appearance of demonstrable antibodies in the blood. (05 Mar 2000) |
| infectious period | <epidemiology> The time period during which infecteds are able to transmit an infection to any susceptible host or vector they contact. Note that the infectious period may not necessarily be associated with symptoms of the disease. (05 Dec 1998) |
| intraoperative period | The period during a surgical operation. (12 Dec 1998) |

| isoelectric period | The period occurring in the electrocardiogram between the end of the S wave and the beginning of the T wave during which electrical forces are acting in directions such as to neutralise each other so that there is no difference in potential under the two electrodes.
