Intended use

Staphylococci are a serious problem for hospital epidemiology. Among them, Staphylococcus aureus is the main pathogenic species and is responsible for septicemia and nosocomial infections.
Multi-drug resistance poses considerable therapeutic problems, particularly with respect to methicillin resistant staphylococci. The ability to rapidly differentiate Staphylococcus aureus from other staphylococci species is therefore a necessity in microbiological diagnosis.

The ELITex Staph is a slide agglutination test for the rapid identification of Staphylococcus aureus (MRSA included) from primary culture plates. It is rapid, easy-to-use and easy-to-read with results available within 1 minute.


Principle

Red latex particles are sensitized with three proteins:

  • Fibrinogen that reacts with “Clumping Factor”
  • The Fc fragment of human IgG that reacts with Staphylococcus aureus protein A
  • Anti-Staphylococcus aureus capsular polysaccharides polyclonal IgG.

The presence of Staphylococcus aureus is revealed by a strong agglutination reaction. In the absence of Staphylococcus aureus, no agglutination appears.

The test procedure is easy with results available in less than a minute.

The kit is complete and includes:

  • TEST LATEX
  • CONTROL LATEX (internal control)
  • Test cards
  • Single use sticks
