Chapter 23.4, Problem 2CC
Summary Introduction
To describe:
An evolutionary trend (in either rabbit or virus) that might occur after a rabbit population first encounters the Myxoma virus.
Introduction:
Myxoma virus is a virus that infects rabbits. It causes myxomatosis in rabbits. This virus was used as a pest control in Australian subcontinent. This virus is very much effective against the host that is it can very easily evade the immune mechanism of hares and rabbits. It causes localized benign fibromas in rabbits and hares.

The current pandemic COVID-19 (coronavirus disease 2019) is caused by 2019-nCoV (2019 novel coronavirus). You just learned about the transmission rate hypothesis for the evolution of pathogen virulence and the power of natural selection. Which of the following statements may go through your mind?
-
For individuals infected with a more virulent viral strain, each cough is likely to contain more virus particles when compared to individuals who are infected with a less virulent strain. Therefore, uninfected individuals will have a higher chance of being infected when encountering the droplets from individuals infected with a more virulent strain.
-
However, individuals infected with a more virulent viral strain is likely to get sick sooner and show severer symptoms, thus will have less time being out and about when compared to individuals infected with a less virulent viral strain.
-
If there is no public health measures on social distancing to prevent congregation,…
Mouse Infection A model for the spread of an infectious dis-
ease among mice is
NP
= rN -
ar(a + b + v)
dt
b + y,
where N is the size of the population of mice, a is the mortal-
ity rate due to infection, b is the mortality rate due to natural
causes for infected mice, B is a transmission coefficient for the
rate that infected mice infect susceptible mice, v is the rate the
mice recover from infection, and y is the rate that mice lose
immunity. Show that the solution to this equation, with the
initial condition N(0) =(a + b + v)/B, can be written as
(a + b + v),
2{(R – a)e" + a],

In 1999, researchers identified a strain of chimpanzee SIV called SIVcpz, which was nearly identical to HIV. Which of the following conclusions could be drawn from the similarities and relatedness that exist between humans and primates based on respective strains of viruses? Mosquitos are vectors of the Simian Immunodeficiency Virus (SIV), and HIV. Once injected with their proboscis and introduced viruses into the human bloodstream, viral mutations occur. Human immunodeficiency virus has reverse transcriptase so it is easier for them to transform into another strain of the virus. The introduction of new viral strains is inevitable and they do not possess selectivity. Both immune host cells from humans and chimpanzees are susceptible to any viral infection. Humans and Chimpanzees were similar so it is easier for the Simian Immunodeficiency…arrow_forward
