Main Features

• 
  Yeast Extract: Provides essential amino acids and B vitamins to support microbial growth.
  


• 
  Activated Charcoal: Neutralizes bacterial toxins and inhibitory substances, improving the recovery of Legionella spp.
  


• 
  Selective Agents: Polymyxin B, Vancomycin and Anisomycin prevent the growth of contaminating bacteria, ensuring the purity of Legionella colonies.

  pH Indicators: Bromothymol Blue and Bromocresol Purple color the colonies, facilitating the identification of microorganisms.
  

Use Technique

Inoculate the medium with a sample using a sterile loop and incubate the plates at 36 ± 2°C in an atmosphere with 90% relative humidity. Legionella pneumophila colonies become visible within 2-5 days, but the plates must be examined daily for 14 days to ensure an accurate result.

Results and Interpretation
Legionella colonies appear light blue or blue-gray and, with prolonged incubation, become larger and whitish-gray. It is essential to subject suspicious colonies to confirmatory tests through Gram staining and other biochemical and immunological analyses.

Storage and Shelf Life
Store Legionella MWY Agar at 2-8°C, protected from light, to ensure maximum effectiveness until the expiration date. Stability studies have shown that the product remains effective even after transport at varying temperatures.
