Chromogenic Media Detects S. typhi and S. paratyphi
Jan 26 2012
bioMérieux’s chromID Salmonella takes advantage of three chromogenic substrates to selectively isolate and differentiate all Salmonella serotypes, including S. typhi and S. paratyphi.
Salmonella spp. are observed 18 – 24 hours after incubation as pale pink to mauve colonies on a colourless background and are easily distinguished from non-Salmonella spp. which appear as blue, turquoise or colourless colonies. This optimum differentiation of cultures virtually eliminates the risk of missing a Salmonella infection.
The performance of chromID Salmonella is enhanced by the medium’s increased nutrient capacity and colour intensity, while the specific esterase activity from Salmonella increases the sensitivity of detection and specificity of colouration, offering greater reliability and performance than previously achievable. Identification and susceptibility testing of Salmonella isolated on this chromID medium correlates well with tests performed after isolation on
a reference medium1, avoiding the need for subculture of strains. Microbiologists using chromID Salmonella can take advantage of a complete solution for the detection of Salmonella, simultaneously benefitting from considerable savings in time and money.
