Rapid catalase supplemental test for identification of members of the family Enterobacteriaceae.
نویسندگان
چکیده
A simple, rapid, semiquantitative slide catalase test useful for differentiating members of the family Enterobacteriaceae is described. Judging by the time required for appearance of oxygen bubbles in 3% hydrogen peroxide, the immediate catalase reactors were Yersinia, Serratia, Proteus, Morganella, Providencia, Cedecea, and Hafnia spp. The delayed catalase reactors were Escherichia, Shigella, Klebsiella, Enterobacter, Salmonella, Citrobacter, Edwardsiella, Kluyvera, and Tatumella spp. This information is especially useful for differentiating Serratia from Enterobacter spp. and Yersinia from Escherichia and Shigella spp.

Catalase test as an aid to the identification of Enterobacteriaceae.
Although the catalase test has been used for many years for rapid differentiation of the genera of gram-positive organisms, little has been said about its use in the family Enterobacteriaceae. It was further noted that a wide variety of methods exist for the execution of the catalase test, that there is no universally accepted strength specified for the hydrogen peroxide, and that no gradations...

متن کاملEfficiency of a multitest system (Enterotube) for rapid identification of Enterobacteriaceae.
Enterotube, a multiple-test system which combines nine biochemical tests useful in the identification of members of the family Enterobacteriaceae, was tested and compared with the PathoTec test system in the identification of gram-negative bacilli isolated from clinical specimens. It was found that both the Enterotube and the PathoTec systems rapidly and accurately defined the position of the o...
