This study compares the performance of different selective-differential media with the overlay method for recovery of stressed cells of Enterobacter sakazakii from infant formula milk (IFM). Five different selective-differential media were used in this study: OK medium, violet red bile agar (VRBA), Druggan-Forsythe-Iversen agar (DFI), Enterobacteriaceae enrichment (EE) agar, and fecal coliform ...
