Piglets are a source of pathogenic Yersinia enterocolitica on fattening-pig farms

Abstract

To study the origin and spread of Yersinia enterocolitica among pigs, fecal and blood samples were repeatedly taken on a fattening farm. A few piglets were found to be already infected on breeding farms. After the piglets were mixed, the infection spread through the whole unit. Eventually, all the pigs excreted the pathogen. © 2012, American Society for Microbiology.
