Staphylococcus Latex Kit – rapid confirmation of S. aureus colonies
The Staphylococcus Latex Kit is a slide agglutination test for the rapid confirmation of Staphylococcus aureus colonies. Latex particles detect clumping factor (bound coagulase) and protein A on the bacterial surface.
- Detects clumping factor and protein A
- Result on the slide within a minute
- 50 tests, with test and control latex
How Staphylococcus Latex Kit works
A colony is mixed with test latex on the card. Clumping factor and protein A of S. aureus bind to the coated particles, and visible agglutination forms within seconds. The control latex excludes non-specific clumping.
Typical results
| Result | Read-out |
| Positive | Agglutination with test latex, none with control latex |
| Negative | No agglutination |
Applications and practical notes
Typical colonies from Baird-Parker or other selective agars are confirmed before they are counted as S. aureus, as described in ISO 6888-1 and FDA BAM Chapter 12. Typical applications include:
- Confirmation of typical colonies from Baird-Parker Agar
- Differentiation of S. aureus from other staphylococci
- Food, pharmaceutical and clinical-environmental laboratories
- Training and method verification
Working with Staphylococcus Latex Kit: Use fresh colonies from non-selective or Baird-Parker Agar and always test the control latex in parallel.
Good practice with rapid tests: store the kit as stated on the label, let the components reach room temperature before use and use each item only once. Record the lot number and the result, and confirm positive results according to the reference method when this is required.
About the Staphylococcus aureus methods: coagulase-positive staphylococci in the food chain are counted on Baird-Parker Agar according to ISO 6888-1, and typical colonies are confirmed with the coagulase test. For low numbers, ISO 6888-3 uses an MPN technique with Giolitti-Cantoni Broth, and the FDA BAM Chapter 12 describes direct plating and an MPN method with Tryptic Soy Broth containing 10 % NaCl. In pharmaceutical microbiology, the test for S. aureus in EP 2.6.13 and USP <62> uses Mannitol Salt Agar. COLO.Science offers media, supplements, rapid tests, identification kits and QC strains for every step.
