Zusammenfassung:infections mainly occur after aspiration of contaminated water or inoculation with polluted environmental materials. spp. have been isolated from anthropogenic environments frequently. To understand their propagation and routes of infection, possible reservoirs of spp. should be explored. In this study, the impact of temperature, diesel and nitrate on populations in soil is described. Soil was treated with diesel and KNO and incubated for nine weeks at 18 and 25 °C. Isolation of strains was done using SceSel+. For the identification of 600 isolated strains, RFLP and rDNA sequencing were used. , , and were isolated at the beginning and/or the end of incubation. Temperature alone had a minor effect on the population. The combination of 25 °C and nitrate resulted in higher numbers. Treatment with 10 g diesel/kg soil and incubation at 25 °C resulted in even higher abundance, and favored and . The results of this study show that diesel-polluted soils favor dispersal of strains, especially and Higher temperature force the effect of supplementations.
