Explanation:
George's doctor will need to culture the isolated S. aureus to determine if the isolated bacterium is the one responsible for the infection.
<h3>What is Koch's postulates?</h3>
Robert Koch was a famous microbiologist that made some postulates as follows:
- The bacteria must be present in every case of the disease.
- The bacteria must be isolated from the host with the disease and grown in pure culture.
- The specific disease must be reproduced when a pure culture of the bacteria is inoculated into a healthy susceptible host.
- The bacteria must be recoverable from the experimentally infected host
According to this question, S. aureus has been isolated from George’s infected wound.
This means that in accordance with Koch's postulates, George's doctor will need to culture the isolated S. aureus to determine if the isolated bacterium is the one responsible for the infection.

Ectoderm refers to one of the three primary germ layers found in the initial phase of an embryo. The other two layers are the endoderm (the most proximal layer) and the mesoderm (the middle layer), the ectoderm is the most distal or the exterior layer. It originates from the external layer of germ cells.
Generally, ectoderm in vertebrates further develops into the brain and the nervous system, and into the parts of the skin. So, in the given case of the mouse, one would easily find the marker in the nervous system and in the epidermis.
