SURVIVAL OF  ESCHERICHIA COLI  SEROTYPE O157:H7 IN CULTIVABLE AND MEADOW SOILS

Survival of one strain of enterohaemorrhagic E. coli serotype O157:H7, isolated from milk in Poland, in cultivable and meadow soils at 5^oC and 20^oC was tested. It was found that the death rate of pathogenic bacteria depends on soil fertility and incubation temperature. At 5^oC, in such soils as light loam and loamy silt, with humus content of 2.16% to 3.43%, bacteria died after 140-158 daysof incubation, and in such soils as loamy sand with humus content of ca. 1.50% they died after 70-85 days of incubation. At 20^oC, these periods for experimental options mentioned above were 70-90 days and 49-63 days, respectively.
