| phylogenomic approaches to determine the zoonotic potential of shiga toxin-producing escherichia coli (stec) isolated from zambian dairy cattle. | this study assessed the prevalence and zoonotic potential of shiga toxin-producing escherichia coli (stec) sampled from 104 dairy units in the central region of zambia and compared these with isolates from patients presenting with diarrhoea in the same region. a subset of 297 e. coli strains were sequenced allowing in silico analyses of phylo- and sero-groups. the majority of the bovine strains clustered in the b1 'commensal' phylogroup (67%) and included a diverse array of serogroups. 11% (41/3 ... | 2016 | 27220895 |
