How to use
In Vitro:
A total of 102 (84%) of the 122 isolates are negative for indole production, unable to assimilate histamine and d-melezitose or to grow at 10°C. All of these 102 isolates are identified as possible K. pneumoniae/K. variicola. Finally, one isolate (1%) is positive for indole production, histamine assimilation, and growth at 10°C and negative for ornithine and d-melezitose. This isolate is identified as possible R. planticola.
