Quantification of Persistence of Escherichia coli O157:H7 in Contrasting Soils
Figure 2
Quantification of E. coli O157:H7 in growth chamber after 60 days in fumigated soils. Fumigant (MeBr) was applied at the normal application rate: non fumigated control: (a) (sandy soil), (b) (clay soil); normal application rate for MeI (c) (sandy soil), (d) (clay soil); normal application rate for Mebr (e) (sandy soil), D (clay soil); E. coli O157:H7 were enumerated from sandy and clay soil by plate count and by real-time PCR (RT-PCR) using stx1, stx2, and the eae genes.
