However, even though both infections have latent periods, the biology of the two types of latency period is somewhat different. The periods of disease include the incubation period, the prodromal period, the period of illness, the period of decline, and the period of convalescence. ... MPDI biology, 9 (3) (2020), p. 50. Literary usage of Latent period. This is a lab question I cant find the answer in the lab manual or in the text book. A persistent pathogen remains viable for a long period outside the host (perhaps When looking at herpes, the infection is often said to be latent between outbreaks of cold sores or genital disease. Latent Infection. There are viruses that are capable of remaining hidden or dormant inside the cell in a process called latency. This is what I'm talking about. Not all animal viruses undergo replication by the lytic cycle. 6.10). The key difference between eclipse and latent period is that eclipse period is the time of synthesizing phage proteins and nucleic acids inside the host cell, while the latent period is the time between injection of the viral genome into the cell and host cell lysis.. A bacteriophage (phage) is an obligate intracellular virus particle that infects and propagates within a specific bacterium. The muscle twitch lasts for about 0.1 seconds.It has three stages: Latent period: It is the period of no contraction and lasts for about 0.01 seconds. A person may carry disease, such as Streptococcus in the throat, without exhibiting any symptoms. Below you will find example usage of this term as found in modern and/or classical literature: 1. Latent heat, energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process; Latent variable, a variable that is not directly observed but inferred in statistics; Biology and medicine. Latent diseases last for years, but are distinguished from chronic diseases by the lack of active replication during extended dormant periods. Science and technology. During the latent period the pathogen is not infectious. Edit: The latent period is the short delay between the muscle action potential and the beginning of muscle tension development. Phase of shortening or contraction: It is the phase when work is done. Please help. What physiological processes in a muscle cause the latent period in a muscle fiber? While latent or latency period may be synonymous, a distinction is sometimes made between incubation period, the period between infection and onset of the disease, and latent period, the time from infection to infectiousness.Which is shorter depends on the disease. The effect of load on the work done by the muscle depends on the way in which the load is applied. CrossRef View … It also reduces the degree of contraction, i.e., the height of the curve (Fig. Latency period or latent period, the time between exposure to a pathogen, chemical or radiation, and when symptoms first become apparent A non-latent pathogen does not need to go through a development, and can cause infection directly after being excreted. These types of viruses are known as latent viruses and may cause latent infections. The latent or exposed period before symptoms and transmissibility, the incubation period before symptoms appear, the symptomatic period, and the transmissibility period, which may overlay the asymptomatic period. The median incubation period was estimated to be 5.1 days (95% CI, 4.5 to 5.8 days), and 97.5% of those who develop symptoms will do so within 11.5 days (CI, 8.2 to 15.6 days) of infection. Phase of relaxation: It is the phase when muscle returns to its previous relaxed state, and recovery is complete. Load lengthens the latent period but reduces the periods of contraction and relaxation. Persistency describes how long a pathogen can survive in the environment. It lasts for about 0.04 seconds.
