The DNase test assignment: The DNase test is sometimes used to help identify different staph species. The is pure green– DNA-green complex which act as indicator. If you streak the plate of this media with staph species (produce DNase) and another plate with staph epidermidis (Does not produce DNase). What would you expecting to see?
A. the Staph aureus plate will have a clear zone around the colonies while the Staph epidermis will not and the media will maintain its plate
B. The Staph aureus plate will have a clear zone around the colonies and the media will maintain its plate green color while the Staph epidermis will have a clear zone.
C. The Staph aureus will have an intense dark green zone around the colonies while the Staph epidermis will not and the media will maintain plate green color.
D. The Staph aureus will not have an intense dark green zone around the colonies while the Staph epidermis an intense dark green zone around the colonies.
