incubation

 [in″ku-ba´shun]
1. the provision of proper conditions for growth and development, as for bacterial or tissue cultures.
2. the development of an infectious disease from time of the entrance of the pathogen to the appearance of clinical symptoms.
3. the development of the embryo in the egg of oviparous animals.
4. the maintenance of an artificial environment for a newborn, especially a premature infant.
incubation period the interval of time required for development; especially the time between invasion of the body by a pathogenic organism and appearance of the first symptoms of disease. Incubation periods vary from a few days to several months, depending on the causative organism and type of disease.

period

 [pēr´e-od]
an interval or division of time; the time for the regular recurrence of a phenomenon.
absolute refractory period the part of the refractory period from phase 0 to approximately −60 mV during phase 3; during this time it is impossible for the myocardium to respond with a propagated action potential, even with a strong stimulus. Called also effective refractory period.
blanking period a period of time during and after a pacemaker stimulus when the unstimulated chamber is insensitive to avoid sensing the electronic event in the stimulated chamber.
effective refractory period absolute refractory period.
ejection period the second phase of ventricular systole (0.21 to 0.30 sec), between the opening and closing of the semilunar valves, while the blood is discharged into the aorta and pulmonary artery. Called also sphygmic period.
gestation period see gestation period.
incubation period see incubation period.
isoelectric period the moment in muscular contraction when no deflection of the galvanometer is produced.
latency period
latent period a seemingly inactive period, as that between exposure to an infection and the onset of illness (incubation period) or that between the instant of stimulation and the beginning of response (latency, def. 2).
refractory period the period of depolarization and repolarization of the cell membrane after excitation; during the first portion (absolute refractory period), the nerve or muscle fiber cannot respond to a second stimulus, whereas during the relative refractory period it can respond only to a strong stimulus.
relative refractory period the part of the refractory period from approximately −60 mV during phase 3 to the end of phase 3; during this time a depressed response to a strong stimulus is possible.
safe period the period during the menstrual cycle when conception is considered least likely to occur; it comprises approximately the ten days after menstruation begins and the ten days preceding menstruation. See the section on fertility awareness methods, under contraception.
sphygmic period ejection period.
supernormal period in electrocardiography, a period at the end of phase 3 of the action potential during which activation can be initiated with a milder stimulus than is required at maximal repolarization, because at this time the cell is excitable and closer to threshold than at maximal diastolic potential.
vulnerable period that time at the peak of the T wave during which serious arrhythmias are likely to result if a stimulus occurs.
Wenckebach's period a usually repetitive sequence seen in partial heart block, marked by progressive lengthening of the P–R interval; see also dropped beat.

1. time interval between invasion of the body by an infecting organism and the appearance of the first sign or symptom it causes; Synonym(s): incubative stage, latent period (2) , latent stage, stage of invasion

incubation period

The interval between the time of infection and the first appearance of symptoms of the resulting disease. Incubation periods vary widely, from as little as a few hours in the case of CHOLERA to many weeks in some cases of RABIES.

For patients with confirmed cases, we estimated the median incubation period to be 5.8 (95% CI 5.0-6.7) days (Figure 1, panel B; online Technical Appendix Table 2) and the mean to be 6.0 (95% CI 5.2-6.8) days.
In this study, a method based on NIRS was explored for quantitative determination of the relative content of Pst DNA in wheat leaves in the incubation period. Based on the acquired near-infrared spectral data of the latently Pst-infected wheat leaf samples and the data on the relative content of Pst DNA in the corresponding samples obtained using the duplex TaqMan real-time PCR arrays, dynamic changes of the relative contents of Pst DNA in the latently Pst-infected wheat leaves during the incubation period were investigated and quantitative determination models were built to realize the quantitative and rapid detection of the pathogen amounts in the latently Pst-infected wheat leaves.
