Biochemical tests: IMViC
Biochemical tests, specifically the IMViC tests, are four individual tests used to differentiate between members of the Enterobacteriaceae family of bacteria. These tests include Indole production, Methyl Red test, Voges-Proskauer test, and Citrate utilization. The IMViC tests are commonly employed in microbiology laboratories for identifying and classifying bacteria, particularly those …
Acid-fast staining
Acid-fast staining is a specialized staining technique used to identify bacteria that have waxy cell walls containing mycolic acids, which are characteristic of certain groups of bacteria, particularly the genus Mycobacterium. This staining method is particularly valuable for detecting and identifying acid-fast bacteria, including the causative agents of tuberculosis (Mycobacterium …
