| 英文摘要 | Complexities of biotic-abiotic interactions in soils result in the lack of integrated understanding of environmental variables that restrict the survival of shiga toxin-producingE. coliO157:H7. Herein, we reanalyzed previously published data and highlighted the influence of soil abiotic factors onE. coliO157:H7 survivability and elucidated how these factors took effect indirectly through affecting indigenous bacterial community. Interaction network analysis indicated salinity and pH decreased the relative abundances of some bacterial taxa (e.g.,Acidobacteria_Gp4,Acidobacteria_Gp6, andDeltaproteobacteria) which were positively correlated with the survival ofE. coliO157:H7 in soils, and vice versa (e.g.,GammaproteobacteriaandFlavobacteria) (P< 0.05). An array of multivariate statistical approaches including partial Mantel test, variation partition analysis (VPA), and structural equation model (SEM) further confirmed that biotic and abiotic factors interactively shaped the survival profile ofE. coliO157:H7. This study revealed that some bacterial taxa were correlated with survival ofE. coliO157:H7 directly, and salinity and pH could affectE. coliO157:H7 survival through changing these bacterial taxa. These findings suggest that salinity in soil might benefit the control of fecal pathogenicE. coliinvasion, while soil acidification caused by anthropogenic influences could potentially increase the persistence ofE. coliO157:H7 in agro-ecosystem. |
