DNA from Salmonella species, when digested with the restriction enzyme Xba I, gives around 15 fragments ranging from 25 kb to 680 kb This pattern of fragments, or ‘fingerprint’, is unique to that strain. If the same fingerprint is found from bacteria from other infected people, then it can be assumed that they were all infected from a common source. Thus, by comparing their eating habits, food sources, etc. the source of the infection can be traced to a restaurant, food item. The fingerprints are created and analysed by
