The 3M Petrifilm STX Plate is a sample-ready-culture medium system which contains a coldwater-soluble gelling agent. The chromogenic, modified Baird-Parker medium in the plate is selective and differential for Staphylococcus aureus but may also indicate Staphylococcus hyicus (S. hyicus) or Staphylococcus intermedius (S. intermedius). 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.
