IMViC

(im'vik),
Acronym for indole production, methyl red, Voges-Proskauer reaction, and ability to use citrate as a sole source of carbon (i inserted for euphony); used primarily to differentiate Escherichia coli from Enterobacter aerogenes and related organisms.

After the incubation Gram staining from colonies, and bacterial identification processes were performed for Gram-negative bacteria with oxidase and IMVIC tests.
Gram negative isolates were identified based on growth characteristics on MacConkey agar and reactions to strip oxidase test, catalase test, Triple Sugar Iron (TSI) agar, and the "IMViC" tests (Indole, Methyl-Red, Vogas Proskaur and Citrate utilisation) [16].
The identification tests for gram positive bacteria were gram stain, coagulase test, catalase test and for gram negative bacteria were gram stain, IMViC (Indole, methyl red, voges-proskauer, citrate), motility, urease, TSI, oxidase were done from an isolated colony.
Identification of bacterial isolates: Selected bacterial isolates were identified by colony morphology, microscopic examination (Gram staining, spore staining, capsular staining) and biochemical characteristics (Catalse test, Oxidase test, Urease test, Coagulase test and IMViC tests)) following Bergey's manual of Determinative Bacteriology, 9th edition (Holt et al., 1994).
Also biochemical tests IMVIC were investigated after the incubation at 37[degrees]C for 48-24 hours.
Em seguida, foram realizadas a analise morfo-tintorial (Gram) e as provas bioquimicas do IMViC (Indol, Voges-Proskauer, vermelho de metila e citrato).
Its identification was again performed on the basis of Gram reaction, motility, IMViC, lactose fermentation, gas production and growth on Endo agar with metallic sheen.
Different biochemical tests such as catalase, oxidase test, O-F tests, IMViC tests, [H.sub.2]S production test etc.
Gram negative bacteria: were identified by Catalase, Oxidase, Motility, IMViC reaction, O-F test, Carbohydrate fermentation test, Amino acid decarboxylation tests.
