The Institute began as an offshoot of the Royal Adelaide Hospital laboratories, being located in Frome Road nearby, in what used to be South Australia's principal teaching hospital precinct. RAH Superintendent and Dean of Medicine Sir Trent Champion de Crespigny created a combined laboratory services with clinical pathology training and medical ...
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 ...
TSI agar slant results: (from left) preinoculated (as control), P. aeruginosa, E. coli, Salmonella Typhimurium, Shigella flexneri The Triple Sugar Iron (TSI) test is a microbiological test roughly named for its ability to test a microorganism's ability to ferment sugars and to produce hydrogen sulfide.

Nancy Atkinson, OBE (also known as Nancy Cook and Nancy Benko; 9 March 1910 – 21 December 1999) was an Australian bacteriologist.In the 1950s, she was recognised as one of the world's leading authorities on bacteriology, and led research on Salmonella bacteria, antibiotic and vaccine development, and the isolation of the poliovirus.
[22] [43] [48] [49] [50] In 2007, the company shipped chopped peanuts on two occasions even after Salmonella was confirmed by private lab tests. [50] The company had previously refused to divulge production test records until federal officials invoked the food safety provisions of a federal antiterrorism law (the 2002 Public Health Security and ...
Although it could be used in other formats (e.g., Petri plates), Simmons' citrate agar is often used in slants or slopes in test tubes. One advantage of using slants over Petri dishes is access to oxygen, which is required by citrate metabolism. Simmons’ agar can be bought from suppliers as ready-made powders or slants.
The Ames test uses several strains of the bacterium Salmonella typhimurium that carry mutations in genes involved in histidine synthesis. These strains are auxotrophic mutants, i.e. they require histidine for growth, but cannot produce it. The method tests the capability of the tested substance in creating mutations that result in a return to a ...
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 ...
