Abstract excerpt

OBJECTIVES: Despite a 97% reduction in clinical sulphonamide usage, the prevalence of sulphonamide resistance among Escherichia coli has remained constant in the UK. Genetic linkage of sulphonamide resistance to other resistances is thought important for this maintenance, but the finding also implies that sulphonamide resistance exerts little fitness cost. To test this hypothesis, we examined the fitness impact...
