Epidemiology
How it spreads and how does it infect its host
Mineralisation
complex molecules turned to simple inorganic molecules
-ales
indicate order
-ceae
indicate family
Type strain
First strain of a species
Biovars
Biochemical and physiological differences
Serovars
Differ in reaction with antibodies
Morphological features
-cell shape and size
-colonial morphology
-staining behaviour
-mechanism of motility
-cellular inclusions
Cellular inclusions
Types of inclusion bodies such as starch/glycogen
Polyphasic taxonomy
As many classifications as possible
