Topic 17: Rapid Identification Methods

Rapid identification methods

________ have been developed that provide a large number of results from one inoculation.

Accuracy

________ is improved by using a series of standardized tests.

I

indole production from trytophan

M

methyl red test for stable acid production from glucose

V

voges-proskauer test for production of acetonin from glucose (unstable acid production)

C

use of simmons citrate as the sole carbon source

Detects enterics

coliformsgram, bacillus

How can accuracy be improved?

using a series of standardized tests

Why were IMViC tests developed?

seprating members of the enterics, particularing the coliforms (to determine whether water was contaminated with sewage)
