In the late 1930s, Australian bacteriologist Nancy Atkinson established a salmonella typing laboratory – one of only three in the world at the time – at the Government of South Australia's Laboratory of Pathology and Bacteriology in Adelaide (later the Institute of Medical and Veterinary Science). It was here that Atkinson described ...
Salmonella is a group of bacteria that can cause foodborne illness. It is commonly associated with undercooked meat and eggs; however, outbreaks have recently been linked to other foods, such as ...

A simple colorimetric test is possible by adding a lactose analog which is degraded by β-galactosidase, producing a colored compound which can be measured quantitatively through spectrophotometry. The degree of color development is an indirect measure of the β-galactosidase produced, which itself is directly related to the amount of DNA damage.
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". These tests are useful in distinguishing members of ...
