This is partly because they require neither the X- nor the V-factor for growth such as required by members of the genus Haemophilus. Mycobacteria Themycobacteria are a group of bacteria that are classified with other Gram-positive bacteria on the basis of their cellular architecture, but they possess a very waxy cell wall, and they rarely stain using conventional protocols such as the Gram stain.

Some of the factors, such as the inoculum density and the incubation temperature, are easy to control, but a laboratory rarely knows the exact composition of a commercial medium or the batch-to-batch variations in its quality, and it cannot take for granted the antimicrobial content of the discs. Haemophili can be seen growing larger near to the staphylococcal colony, where the supply of NAD is greatest.
