Phenotypic and genotypic characteristics of the E. coli strains studied.

aPhylogenetic groups determined as in [74].bVirulence genes determined as in [73], (+) presence, (−) absence. All these data are from [72] except the amoeba model data that have been generated in this work.cPhenotypes tested as in [72], abbreviations used are: RSer: serum resistance, RBil: bile resistance, RLys: lysozym/lactoferrin resistance, Mot: motility, GenTim: generation time. Binarization of data in [72].dBiological model tested: mouse [73], [72], K: mouse killer (9 or 10 mice killed over the 10 inoculated), NK: mouse non-killer (no mouse lethality or 1–5 mice over the 10 inoculated), D.discoideum, G: grazing, GR: grazing resistance.
