摘要: Antimicrobial resistance (AMR) in pig populations is a public health concern. There lack of information spatial distributions AMR genes at large scales. The objective the study was to describe pattern faecal samples from farms and test if were spatially randomly distributed with respect geographic distribution farm population risk. Faecal 687 Danish collected February March 2015. DNA extracted levels seven (ermB, ermF, sulI, sulII, tet(M), tet(O) tet(W)) quantified on high-throughput real-time PCR array. Spatial differences for measured as relative quantities evaluated by cluster analysis creating risk maps using kriging kernel density estimation. Significant clusters identified ermB, sulII tet(W). broad trends evident agreement results analysis. However, they also showed that there only small scale gene levels. We conclude geographical location not major determinant presence or high assessed this study.
