Thermo Scientific™ Chromogenic Cronobacter Isolation Agar (Dehydrated)

Description

• Differentiate and enumerate Cronobacter sakazakii from infant formula and other food samples with Thermo Scientific™ Oxoid™ Chromogenic Cronobacter Isolation Agar (Dehydrated)
• Chromogenic Cronobacter Isolation Agar (CCI) is an enhanced formulation of Brilliance ™ Cronobacter Sakazakii Agar (DFI) with improved specificity and colony coloration for the detection of Cronobacter
• Cronobacter sakazakii is a Gram-negative rod-shaped bacterium that rarely causes disease in healthy adults
• It has been implicated in outbreaks of disease in premature infants (neonates)
• Research suggests that neonates, or those infants who have other medical conditions, are more susceptible to this infection
• Most reported cases of infection are severe, including sepsis (bacteria in the blood, meningitis, or necrotizing enterocolitis (severe intestinal infection)
• Use Chromogenic Cronobacter Isolation Agar for differentiation and enumeration of Cronobacter sakazakii from infant formula and other food samples
• Selective: due to the presence of desoxycholate the medium is selective against most Gram-positive organisms
• Easy-to-read: Cronobacter sakazakii produces blue-green colonies on this medium
• Cronobacter spp
• have been isolated at low levels from powdered infant formulae, and the organisms’ high tolerance to desiccation provides a competitive advantage in the dry environments of milk powder factories, increasing the risk of product contamination 1
• Chromogenic Cronobacter Isolation (CCI) agar is an optimisation of the original Brilliance™ Enterobacter Sakazakii Agar (DFI), developed by Iversen et al
• in 2004 3
• The concentration of the X-α-glucoside chromogen was increased to improve the blue-green colouration of Cronobacter strains with weak glucosidase activity
• Sodium thiosulphate and ammonium iron (III) citrate are included to differentiate hydrogen sulphide-producing Enterobacteriaceae, which are coloured grey/brown, and sodium deoxycholate is added to inhibit the growth of Gram-positive competitors
