The Most Common Method Used by Clinical Microbiology Labs for Identifying

Question

The most common method used by clinical microbiology labs for identifying bacteria are _________.
A)biochemical
B)morphological
C)PCR
D)DNA fingerprinting

Accepted Answer

Biochemical tests are the most commonly used method for identifying bacteria in clinical microbiology labs. These tests involve observing the bacteria's reaction to various substances and identifying characteristics such as enzyme production, sugar metabolism, and gas production. Morphological methods involve examining the bacteria's shape, size, and staining properties under a microscope, but these are not always sufficient for identification. PCR and DNA fingerprinting are more specialized techniques used for specific purposes and are not typically used for routine bacterial identification.
