Abstract
A test for the detection of bacteria of the genuses Salmonella and Serratia and distinguishing them from the genuses Proteus and Providencia carried out in the presence of a diazonium salt and a synthetic enzymatic substrate in the form of an ester having an aliphatic chain of 7 to 10 carbon atoms. Two reactions may be effected in the same reactive medium. The test may be associated with other tests such as the .beta.-glucosidase, .beta.-galactosidase and .beta.-glucuronidase research tests making it possible to apply it simultaneously to the detection of bacteria belonging to other genuses: Kliebsiella, Enterobacter, Escherichia.
