Trimethoprim/sulphonamide resistance in Salmonella Typhimurium (all phage types) from domestic livestock in 2004 - 2014

The data shows trimethoprim/sulphonamide antimicrobrial resistance in all phage types of Salmonella Typhimurium from cattle, sheep, pigs, chickens, turkeys and ducks over the period 2004 - 2014. The data is grouped by year, with totals of cultures tested and their percentage resistance to trimethoprim/sulphonamide. Phage typing of Salmonella further subcategorises Salmonella serotypes. A Salmonella isolate is a cultured instance of Salmonella from a sample. An 'incident' is the confirmation of the same Salmonella type on one or more occasion within a set time period (usually thirty days), and within the same group of animals or same location. To better indicate the prevalence of resistance, only the first isolate from each incident has usually been tested.
