The case study describes a cluster of food poisoning incidences. If the causative agent is Salmonella spp., then give your prediction of the IMViC results. (Use the information in your supplement for your prediction)

The term "IMViC" is an acronym for each of these tests. "I" is for indole test; "M" is for methyl red test; "V" is for Voges-Proskauer test, and "C" is for citrate test. The lower case "i" is merely for "in" as the Citrate test requires coliform samples to be placed "in Citrate". Triple sugar iron test (TSI), Urease Test and Malonate Test are also included in this test.

For each of the tests, different reagents are added  to the species are inoculated and tested.

For Salmonella sp. the IMViC Test result is:

Indole - negative

Methyl red - Positive

Voges-Proskauer - negative

Citrate - positive

the answer is c.
