This photo shows the IMViC test results for E.coli. The IMViC tests are useful for differentiating the Enterobacteriaceae, especially when used alongside the urease test. IMViC tests are particularly useful for differentiating Escherichia coli, Enterobacter aerogenes, Enterobacter cloacae, and Klebsiella pneumoniae.

The IMViC series includes four tests:

1. Indole Test
Aim: To detect the production of indole from the degradation of the amino acid tryptophan.
Result: Formation of red or pink colored ring at the top is taken as positive.

2. Methyl Red test
Aim: To detect the production of acids during the formation of sugars.
Result: Development of red color is taken as positive. MR negative organisms produce yellow color.

3. Voges-Proskauer test
Aim: To detect the production of acetyl methyl carbinol (acetoin) from glucose.
Result: Appearance of red color is taken as positive.

4. Citrate Test
Aim: To detect the ability to utilize citrate by microorganisms.
Result: Development of blue color indicates positive test and green is negative.
