Abstract
A meat factory commensal bacterium, Acinetobacter calcoaceticus , affected the spatial distribution of Escherichia coli O157:H7 surface colonization. The biovolume of E. coli O157:H7 was 400-fold higher (1.2 × 10 6 μm 3 ) in a dynamic cocultured biofilm than in a monoculture (3.0 × 10 3 μm 3 ), and E. coli O157:H7 colonized spaces between A. calcoaceticus cell clusters.Keywords
