Ampicillin MacConkey Agar Base – 250g | Selective Medium for Aeromonas hydrophila
Ampicillin MacConkey Agar Base is a selective medium designed for isolation of Aeromonas hydrophila from clinical, food, and environmental samples, combining bile salt inhibition with antibiotic selection.
Key Applications:
✔️ Isolation of A. hydrophila from wound infections
✔️ Detection in aquaculture systems
✔️ Seafood safety monitoring
✔️ Water quality testing
Supplement Requirement:
– Add 1 ampicillin vial per 100ml medium
Selective Components:
– Bile salts: Inhibit Gram-positive bacteria
– Ampicillin: Suppresses competing flora
– Lactose: Differentiates fermenters
Protocol:
1️⃣ Suspend 57.0g in 1L water
