IMViC tests of Proteus vulgaris
Description
FIG. 5. Results of an IMViC series done on Proteus vulgaris after a 24-hour incubation at 37°C.  Tube A shows a positive indole test in tryptone broth. The positive result is indicated by the red layer at the top of the tube after the addition of Kovács reagent. Tube B shows a positive methyl red test as indicated by the red color after the addition of methyl red reagent. Tube C shows a negative Voges-Proskauer test as indicated by the lack of color change after the addition of Barritt’s A and Barritt’s B reagents. Tube D shows a negative citrate result as indicated by the lack of growth and color change in the tube. (Anne Hanson, University of Maine, Orono, ME)
