E&O Laboratories Ltd Cefotaxime Selective Supplement can be used with MacConkey Agar for the isolation of ESBL (Extended Spectrum Beta-Lactamase) producing organisms with the aim of simplifying the differentiation and presumptive identification of Lactose & Non-Lactose fermenting organisms. It should be noted that AmpC isolates may also be detected on this medium whilst non – ESBL organisms will be inhibited on this medium.
Sodium Chloride is omitted from this medium to provide an electrolyte deficient medium that prevents Proteus spp. from spreading.
