Abstract

Sourcing Antibiotic Resistance It is widely assumed that antibiotic resistance in farm animals contributes in a major way to antibiotic resistance in humans. Mather et al. (p. 1514 , published online 12 September; see the Perspective by Woolhouse and Ward ) analyzed hundreds of genome sequences from Salmonella isolates collected from both livestock and patients in Scotland between 1990 and 2004. The relative contributions of animal-derived and human-derived sources of infection were quantified and the phylogenetic diversity of resistance profiles was matched with bacterial phylogenies. The results suggest that most human infections are caught from other humans rather than from livestock and that humans harbor a greater diversity of antibiotic resistance.
