Rapid glutamic acid decarboxylase test for identification of Bacteroides and Clostridium spp.
A rapid 4-h test for glutamic acid decarboxylase is described for the identification of certain anaerobic bacteria. The test substrate consisted of 1.0 g of L-glutamic acid, 0.3 ml of Triton X-155, and 0.05 g of bromcresol green sodium salt in 1 liter of water. The substrate was dispensed in 0.5-ml amounts into test tubes, and a turbid suspension was made with the test organism. The test was th...
متن کاملA rapid glutamic decarboxylase test for identification of bacteria.
A simple rapid glutamic decarboxylase test is described. This test was found useful in the identification of Escherichia coli, Shigella sp., Providencia alcalifaciens, Clostridium perfringens and Bacteroides fragilis.
متن کاملCharacterization of anaerobic bacteria by using a commercially available rapid tube test for glutamic acid decarboxylase.
A rapid glutamic acid decarboxylase microdilution test for presumptive identification of certain anaerobic bacteria was marketed recently by Carr-Scarborough Microbiologicals, Inc., Stone Mountain, Ga. The test was evaluated with 474 clinical isolates, representing 11 genera and 54 species, and was found to be a useful aid in the presumptive identification of Bacteroides fragilis, B. distasonis...
متن کاملNew rapid identification test for Clostridium difficile.
AIMS A set of five tests were developed and tested for their ability to confirm the identity of C difficile colonies within 30 minutes. METHODS The relevant substrates were incorporated into four filter paper squares attached to a plastic carrier (Diffstrip), five enzymes/products (prolyl aminopeptidase, galactosidase, leucine aminopeptidase, acid phosphatase and indole). The strips were inoc...
متن کاملRapid ornithine decarboxylase test for the identification of enterobacteriaceae.
Conventional methods for detecting ornithine decarboxylase activity require an extended period of incubation. However, with a few simple modifications, accurate results were obtained within a few hours rather than several days. The broth medium was modified, primarily by omitting glucose and by decreasing the pH to 5.5. A 1-ml amount of this broth was inoculated with one colony and then overlai...
