The genus Mycobacterium is an important cause of a diverse group of infectious diseases. Because of this, a special acid-fast staining procedure is used to visualize these bacteria. This waxy coat protects the bacteria from some antibiotics, prevents them from drying out, and blocks penetration by Gram stain reagents (see Staining Microscopic Specimens). The genus Mycobacterium is represented by bacilli covered with a mycolic acid coat.
