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, Klebsiella sp. bacteria (left) were tested alongside Escherichia coli organisms. This method incorporates a two-tube system, whereupon, one tube tests for hydrogen sulfide production, phenylalanine deaminase, lysine decarboxylase, lactose utilization, and gas production from glucose, and the other tube tests for indole production, ornithine decarboxylase, and motility.
