EMB Agar - Enteric Pathogen Specialist

Eosin Methylene Blue Agar selective components (eosin, methylene blue, bile salts) inhibit Gram-positive organisms while dyes precipitate in lactose-fermenting colonies producing characteristic dark purple colonies with metallic green sheen (E. coli). Non-lactose fermenters appear colorless/transparent facilitating rapid coliform screening.

Enteric Isolation Applications

Primary screening for E. coli and coliforms from water, food, clinical specimens. Detection of Salmonella/Shigella (colorless colonies). Environmental monitoring and food safety testing. Rapid preliminary identification reducing confirmatory testing requirements.

Performance Characteristics

19mm x 15mm x 20ml plates (Cat. 0802500E), 10 pcs/stack. SFDA standards, ISO 13485 facilities. Clear fermentation differentiation, selective Gram-negative support, stable indicator system.

Laboratory Protocol

Primary streak isolation, 35-37°C aerobic 24h. Metallic sheen = E. coli confirmation. Colorless = non-fermenter workup.
