Nine soil types from sites with various levels and history of contamination by insecticides were chosen as inoculums sources for the present studies. The presences of four groups of soil microorganisms (organic nitrogen bacteria, inorganic nitrogen bacteria and actinomycetes, bacteria and actionmycetes which lives in poor media and Fungi) in these soils were surveyed using selective media. The results indicated that organic nitrogen bacteria is more prevalent and found in all types of soils followed by inorganic nitrogen bacteria and actinomycetes, fungi and bacteria and actinomycetes which lives in poor media. however the bacteria Mycobacterium and the actionmycetes Bactoderm were associated with highly polluted soils.
