Petrifilm™ Staph Express

The Neogen® Petrifilm® Staph Express (STX) System consists of a Petrifilm® Staph Express Count (STX) Plate and a Petrifilm® Staph Express (STX) Disk, which are packaged separately. The 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). By identifying S. aureus in food and environmental samples, Petrifilm® Staph Express Count Plates give food processors an indication and risk assessment of food quality and sanitation effectiveness. Distinctive red-violet colonies appear in as little as 22 hours. The test requires only one incubation temperature and is equivalent to the BAM three plate Baird-Parker agar and tube coagulase method. The end result is better inventory management, better process control, a higher quality product and improved cost savings for your facility, all of which can lead to higher profitability.
