  Rezumat:  Microflora of leaf surfaces of narrow-leaved cattail plants grown in unpolluted and polluted habitats was studied. Total numbers of microorganisms were determined, the colonies were studied morphologically and the purified strains were identified using molecular biological techniques. There was a reduction in the number of microorganisms on polluted leaves in comparison to those collected from unpolluted site. The colony-forming microorganisms belong to different groups: yeasts, Gram-negative bacilli and coccobacilli, Gram-positive nonsporogenous and endospore-forming rod-shaped bacteria, actinomycetes and cocci. The species composition of microflora was very different in the phyllosphere of plants grown on unpolluted and polluted sites. The percentage of Gram-negative bacteria was higher in the case of unpolluted leaves, while on the leaf surfaces of polluted plants the predominant group was represented by Gram-positive bacilli and cocci.
