Salmonella. Steven L. Percival, David W. Williams, in Microbiology of Waterborne Diseases (Second Edition), 2014 Basic Microbiology. As a group, Salmonella are facultatively anaerobic, non-spore-forming, Gram-negative bacillus-shaped bacteria. On average they are 2–5 μm long and 0.8–1.5 μm wide. Motility, aided by peritrichous flagella, is a .

Urease test is an analytical method practised to identify the urease positive and negative organisms based on the production of cytosolic urease enzyme. It distinguishes the Proteus species from the non-lactose fermenting members belonging to the Enterobacteriaceae family. Urease test makes the use of urea base.Key biochemical tests are fermentation of glucose, negative urease reaction, lysine decarboxylase, negative indole test, H2S production, and fermentation of dulcitol.
