What is the clinical significance of using media and other biochemical test to distinguish between similar and dissimilar bacteria?

Biochemical tests and use of media allow physicians to identify the type of bacteria causing a disease (such as whether its gram+ or gram-) and use appropriate antibiotic effective against the bacteria. Another clinical significance is to determine the resistance of bacteria to antibiotics (this is conducted using susceptibility tests).

the  frequency of a wave represents  the number of wavelengths that pass a specific point per second. the unit for  frequency  is hertz (hz).
