Infected virulence

WebVirulence is one of three factors that influence a strain’s R value, as shown in Table 1. If Dhigh is the average number of days a host lives after being infected by the high-virulence strain, and Dlow is the average number of days a host lives after being infected by the low-virulence strain, then, by definition, Dhigh < Dlow. From now on, I ... WebViruses can reproduce only within a host cell. The parental virus (virion) gives rise to numerous progeny, usually genetically and structurally identical to the parent virus. The actions of the virus depend both on its destructive tendencies toward a specific host cell and on environmental conditions. In the vegetative cycle of viral infection, multiplication of …

WebThe life cycle of bacteriophages has been a good model for understanding how viruses affect the cells they infect, since similar processes have been observed for eukaryotic viruses, which can cause immediate death of the cell or establish a latent or chronic infection. Virulent phages typically lead to the death of the cell through cell lysis.
