The spread of antibiotic resistance from concentrated animal feeding operations (CAFO) to soil, crops, and waterways is of international concern and little research has been done with regards to the genetic mobility and persistence of resistant genes. Working with a local swine farmer, the researcher will build on previous work, studying E.coli levels in soil fertilized with swine manure, quantifying the amounts of seven antibiotic-resistant genes in manure and soil samples, pre- and post-manure application.
