ABSTRACT
Salmonella and Shigella Both these organisms are important in food poisoning. They are both nonlactose fermenters. Salmonella are flagellate organisms and are motile, whilst Shigella have no flagella and are therefore non-motile. But can you remember which one is the motile one when you are under pressure? Well you can easily – if you think of a salmon and remember that it is motile – so is Salmonella!
