IMVIC farmula for e.coli is ++--
The IMViC test results that would indicate the presence of fecal coliforms are negative for indole production, positive for methyl red test, negative for Voges-Proskauer test, and positive for citrate utilization.

Quality control in IMViC (Indole, Methyl Red, Voges-Proskauer, and Citrate tests) is performed by using control strains that provide known results for each test. These control organisms ensure the reliability of the test results and help identify any inconsistencies in the testing procedure. Regular calibration of equipment and adherence to standardized protocols further support the accuracy and validity of the IMViC tests. Additionally, periodic reviews and documentation of results contribute to maintaining quality assurance in the microbiological analysis.

IMViC results for Proteus vulgaris are typically indole negative, methyl red positive, Voges-Proskauer negative, and citrate positive. TSI results for Proteus vulgaris show alkaline/alkaline (red/red) slant/butt with no gas production and no hydrogen sulfide production.
Enteroinvasive E. Coli
E. coli is catalyse test positive.
Motile according to the Motility-Indole-Ornithine Test.
For the Indole test, you add Kovac's reagent. For the Methyl Red test, you add Methyl Red indicator. For the Voges-Proskauer test, you add alpha-naphthol and potassium hydroxide. And for the Citrate test, you add Simmons citrate agar.
When a product has the Ecoli bacteria and you consume it.
The IMViC test (Indole, Methyl Red, Voges-Proskauer, Citrate) is useful in identifying Enterobacteriaceae because it helps differentiate between different members within this bacterial family based on their biochemical characteristics. Each test targets a specific metabolic pathway that can be used to distinguish between different genera or species of Enterobacteriaceae. This information can aid in the accurate identification of a particular strain and help determine its pathogenic potential.
