tcsc6328 D- (+) -Melezitose

D-(+)-Melezitose can be used to identify clinical isolates of indole-positive and indole-negative Klebsiella spp.

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^[1].
