Table 3 Relationships among super-shedder status (yes/no), sampling (1 vs 2) and membership in the most prevalent restriction endonuclease digestion pattern cluster, REPC A , as compared to all other REPC for fecal isolates of E. coli O157:H7 collected in Alberta Canada in 2007 from generalized linear mixed model analysis z

From: Genetic diversity and antimicrobial resistance among isolates of Escherichia coliO157: H7 from feces and hides of super-shedders and low-shedding pen-mates in two commercial beef feedlots
