Comparative pathogenesis of Yersinia enterocolitica biotypes
… enterocolitica strains are categorized into six biotypes (1A, 1B, 2, 3, 4 &5). These six biotypes are further classified into high pathogenic, low pathogenic and non-pathogenic biotypes depending on their pathogenicity in the mouse infection model. This project compared the pathogenic potential …
