EF-18 Agar is used for the selective and differential isolation of Salmonella, using the ISO-GRID® and/or NEO-GRID® Membrane Filtration System. EF-18 Agar is not intended for use in the diagnosis of disease or other conditions in humans.
EF-18 Agar was developed for the primary selective isolation of presumptive Salmonella spp. from enrichment broth using the ISO-GRID System. This medium suppresses growth of Gram-positive bacteria and certain Gram-negative bacteria, while enhancing growth of Salmonella spp. EF-18 Agar aids in differentiating Salmonella spp. from other Enterobacteriaceae based on lysine decarboxylase and sucrose fermentation reactions. EF-18 Agar is incubated at 42°C, providing additional selectivity against certain Gram-negative bacteria.
EF-18 Agar is recommended for the primary differential isolation and detection of Salmonella spp. from all foods using the ISO-GRID and /or NEO-GRID Membrane Filtration System.
