Bacteria are classified and identified to distinguish one organism from another and to group similar organisms by criteria of interest to microbiologists or other species are identified in the clinical laboratory by morphological traits and biochemical tests, some of which are supplemented by serologic assessments ( eg,. Any basic dye such as methylene blue, safranin, or crystal violet can be used to color the bacterial cells to the cell surface after staining, bacterial cell morphology (shape and arrangements) can be appreciated diagnostic microbiology laboratory generally do not perform simple staining method.
