Used in the identification of Enterobacteriaceae bacteria, this image depicts four test tubes used in a Diagnostic Research, Inc., R/B Enteric Differential System test. In this particular view, Providencia sp. bacteria were tested, alongside Citrobacter spp. organisms. This system uses a two-tube system, which incorporates into one tube, the tests for hydrogen sulfide production, phenylalanine deaminase, lysine decarboxylase, lactose utilization, and gas production from glucose metabolism, and in the other tube, the tests for indole production, ornithine decarboxylase, and motility.
