Animal microbiology questions.

1. Microbial organisms are often described within their “domains”. What are these domains and how do they differ?
2. Not included in the domains (a-above) are the so called agents of disease. Name these and specify at least ONE disease caused by each.

Classification and nomenclature are important approaches in describing living organisms.

2. Name four bases, other than morphological appearance, upon which bacterial organisms are characterized
3. Which of these methods is considered the most definitive/ conclusive?
