3M™ Petrifilm™ Staph Express Disks have to be used to distinguish Staphylococcus aureus from all suspect colonies. Used when background flora exists in your staph testing. This disk is used to identify Staph aureus from all suspect colonies. It is designed for the detection of desoxyribonuclease (DNase) reactions specific for Staphylococcus aureus isolated on the 3M™ Petrifilm™ Staph Express count plate. The 3M™ Petrifilm™ Staph Express disk must be used whenever colonies other than red-violet are present on the count plate.
The 3M Petrifilm STX Disk contains toluidine blue-O that facilitates the visualization of deoxyribonuclease (DNase) reactions. DNase-positive organisms detected on the 3M Petrifilm STX Plate include Staphylococcus aureus (S. aureus). The 3M Petrifilm STX Plates and 3M Petrifilm STX Disks are used for the enumeration of DNase positive Staphylococcus species in the food and beverage industries. 3M Petrifilm STX Plate and 3M Petrifilm STX Disk components are decontaminated but not sterilized.
