Gram Negative Bacilli
Shigella can be differentiated from E. Coli by all of the following features except: (AIIMS May11)
|A||Shigella does not produce gas from glucose|
|B||Shigella does not ferment lactose|
|C||Shigella does not ferment mannitol|
|D||Shigella is non motile|
S. dysenteriae does not ferment mannitol but other species of shigellae (S. flexneri, S. boydii and S. sonnei) all ferment mannitol.
Unlike Escherichia, the members of genus Shigella are nonmotile, anaerogenic and NLF.
