- •
Two chromogenic agars were compared for the isolation of ESBL Enterobacteriaceae.
- •
Both agars had comparable sensitivity and selectivity.
- •
Sensitivity after direct plating was higher when incubated for 48 versus 24 hours.
- •
Using pre-enrichment with 24-hour incubation further increased the sensitivity.
- •
There was a loss of selectivity after 48-hour incubation for all methods
