Table 4. Sensitivity of 4 different media with supplemented with α-glucosidase substrates, 5-bromo-4-chloro-3-indolyl-α-D-glucopyranoside (BCIG) or 4-methyl-umbelliferyl α-D-glucoside (α-MUG), in 58 strains of E. sakazakii (Cronobacter spp.) at 37°C for 24 h

Media	Total of E. sakazakii	Positive of E. sakazakii	Negative of E. sakazakii	Percentage of recovery (%)
Oxoid	58	56	2	96.6
OK	58	56	2	96.6
VRBG	58	56	2	96.6
NGTE	58	56	2	96.6

Percentage of recovery = [Positive / Total of E. sakazakii (Cronobacter spp.)] × 100.
