Master Vibrio Cholera Characteristics with Picmonic for Medicine

Vibrio cholera is a bacillus, meaning it is shaped like a rod.

This species is able to ferment glucose, which is a unique property allowing differentiation of the species from other similar bacteria.

The species is unable to ferment lactose as an energy source. This inability to ferment lactose is a distinguishing factor which helps with species identification.

The species contains the enzyme oxidase. Other oxidase positive organisms are Pseudomonas and Campylobacter jejuni.

The characteristic shape of cholera is comma shaped when examined under microscope.

The factor that differentiates Campylobacter jejuni from Vibrio cholera is that cholera grows in an alkaline environment.

Vibrio species are classically found in seafoods, particularly crustaceans.
