FIGURE 6.
Regression analysis showing a positive correlation between the moisture level (%) and the load of Salmonella Enteritidis (SE) and Salmonella Typhimurium (ST) in soil incubated at 5, 25, and 37°C. (A) Soil inoculated with SE and incubated at 5°C. (B) Soil inoculated with SE and incubated at 25°C. (C) Soil inoculated with SE and incubated at 37°C. (D) Soil inoculated with ST and incubated at 5°C. (E) Soil inoculated with ST and incubated at 25°C. (F) Soil inoculated with ST and incubated at 37°C. Blue lines show moisture level (%), while purple lines show log10 CFU/g of soil.
