Trimethoprim/Sulphonamide Resistance in Salmonella Typhimurium from Pigs, 2002-2014

APHA laboratory data tracks resistance to trimethoprim/sulphonamide in four specific phage types of Salmonella Typhimurium isolated from pigs. The dataset provides annual totals of cultures tested and their percentage resistance from 2002 to 2014. Data originates from UKAS-accredited laboratories at the Animal and Plant Health Agency, adhering to ISO 17025 and other quality standards.

Use Cases

• Modeling temporal trends in antimicrobial resistance based on annual percentage data.
• Analyzing resistance patterns across different Salmonella Typhimurium phage types mentioned in the description.
• Correlating veterinary surveillance data with public health outcomes based on the described laboratory standards.

Strengths

• Data spans a 13-year period from 2002 to 2014, providing a long-term view of resistance trends.
• Laboratory methods are accredited to specific international standards (BS EN ISO 17025:2000, ISO 9001:2000).
• Data is grouped by year with clear metrics: total cultures tested and percentage resistance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data may reflect temporal and source bias inherent to the specific UK surveillance program.
