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.
The Petrifilm Plate Advantage
In today’s environment of heightened focus on food safety and increasingly stringent quality requirements, labs are under pressure to provide tests that are fast, reliable and consistently accurate. Petrifilm Plates have demonstrated consistent performance that has been cited globally with more than 200 certificates, recognitions, validations, and peer-review publications. For almost 40 years, food safety professionals around the world have put their trust in Petrifilm Plates. That’s because Petrifilm Plates have streamlined, standardizsd and simplified the process of microbial quantitative indicator testing, improving productivity and helping ensure the highest levels of product quality.
Neogen® Petrifilm™ Staph Express Count Plates provide confirmed Staphylococcus aureus results. Confirmed Staph aureus appears as distinctive red-violet colonies. If you encounter high background flora in your staph testing, the Petrifilm Staph Express Disk can be used to identify Staph aureus from all suspect colonies.
