DEVELOPMENT AND CHARACTERISTICS OF POTENTIALLY PATHOGENIC FUNGI IN POLLUTED SOILS

The presented work is devoted to the study of regularities of the distribution of potentially pathogenic fungi in oil-contaminated soils and the ground layer of air in Baku. It is revealed that, oil-contaminated soils are characterized by a more diverse species diversity of microorganisms. A comporative analysis of the samples taken from the soil and air in the Binagadinsky district of Baku City showed a high number and species diversity of soil microbiota. Thus,the soil microbiota is represented by 34 species of 10 genera, and the ground air microbiota is represented by 25 species of 8 genera of micromycetes. It is also determined that oil contamination of soils is the main factor in the transformation of saprotrophic forms into conditionally pathogenic fungi. It was found that oil contaminated, as an anthropogenic factor, stimulates the functional activity of soil mycobiota and is considered one of the main arguments in the transformations of saprophytic micromycetes into opportunistic fungi. And this proves that both in oil-contaminated soils, as well as in the surface layer of air, the frequency of occurence of conditionally oil micromycetes depends on the degree of pollution. It is revealed that in the contaminated soil there exist allergenic and opportunistic representatives and after a white migrating in the air they turn into a potential source of infection. It was determined that in the mycocomplexes, which forms in oil-contaminated soils,allergenic and conditionally cultivated fungi, in comparison with other micromycetes, develop very quickly and their sporulation is realized in a short time and this contributes to an increase in the risk factor for diseases among the population.
