Description
Yersinia Selective Agar Base is a selective differential medium for isolating Yersinia enterocolitica.
Mannitol and neutral red produce characteristic red-centred bull's-eye colonies, while deoxycholate, crystal violet and the cefsulodin–irgasan–novobiocin supplement inhibit competing flora.
Samples or PSB enrichments are plated and incubated at 30 ± 1°C for 18–24 hours. Characteristic colonies require biochemical confirmation.
