Summary Introduction

To write:

Differentiation of S.pyogenes infection causing strep throat and scarlet fever.

Given:

Streptococcus pyogenes causes strep throat and scarlet fever in some patients. Differentiate S.pyrogenes infection causing strep throat and scarlet fever.

Introduction:

Streptococcus pyogenes causes strep throat and then scarlet fever. To differentiate these two infections, one should identify the presence of a toxin in scarlet fever and the absence in strep throat. So it is clear that S. pyogenes producing erythrogenic toxin causes scarlet infection.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
