- This research project aims to compare techniques to identify strains of salmonella, this is will help in tracing human infections back to their source.
This project aimed to compare a number of molecular techniques e.g. plasmid profiling, pulsed field gel electrophoresis, fluorescent amplified fragment length polymorphisms and sequence polymorphisms in a gene conferring resistance to the antibiotic ciprofloxacin to investigate whether a combination of the methods could subdivide S. typhimurium DT104 strains more effectively.

- In the tracing of human infections back to their source e.g. from the manufacturing environment, farm etc., it is necessary to be able to separate bacterial species or strains into a sufficiently large number of subtypes that the offending organism can be identified with a reasonable degree of certainty.
At the beginning of this project the methods in use to sub-divide salmonella phage types when applied to S. typhimurium DT104 placed more than 95% of the isolates in a single group.
