For differentiating Salmonella arizonae from the Bethesda Ballerup group of Enterobacteriaceae.

Description

Lysine Decarboxylase HiVegTM Broth is recommended for differentiating Salmonella arizonae from the Bethesda Ballerup group of Enterobacteriaceae. During the initial stages of incubation, following inoculation, fermentation of dextrose by the organisms leads to acid production, which causes a subsequent colour change of the bromocresol purple indicator to yellow. The acidic condition thus generated stimulates decarboxylase activity, which leads to decarboxylation of lysine to cadaverine. The alkaline conditions generated due to cadaverine production cause the bromocresol purple indicator (changed to yellow) to revert to purple colour. If the organisms do not produce decarboxylase enzyme, the colour of the medium remains yellow. Dextrose non-utilizers will not show any change in the medium colour. Lysine Decarboxylase HiVegTM Broth is prepared by using vegetable peptones in place of animal based peptones which make the media free of BSE/TSE risks.
