The topsoils and atmospheric dust aerosols of the various areas of the city of Moscow were studied. Most of the dust samples contained a considerable number of particles enriched in phosphorus - a sign of contamination by feces. A variety of species, including opportunistic and pathogenic species, were isolated from the topsoil and dust samples and identified using 16S rDNA nucleotide sequences: and . The greatest diversity of pathogens was isolated from spring soil and dust samples immediately after spring snowmelt. Antibiotic resistance of the isolated strains was tested using disks with a wide range of antimicrobial drugs: Amoxicillin, Ampicillin, Meropenem, Pefloxacin, Streptomycin, Ticarcillin+clavulanic acid, Fosfomycin, Ceftibuten, Ciprofloxacin. Resistance was observed in more than 22% of strains. The traffic area had a significant number of antibiotic-resistant strains, clearly indicating a high health risk from soil and dust exposure.
对莫斯科市不同区域的表层土壤和大气尘埃气溶胶进行了研究。大多数灰尘样本含有大量富含磷的颗粒——这是粪便污染的迹象。从表层土壤和灰尘样本中分离出了包括机会致病菌和致病菌在内的多种物种，并使用16S rDNA核苷酸序列进行了鉴定：以及。在春季融雪后立即从春季土壤和灰尘样本中分离出的病原体种类最为多样。使用含有多种抗菌药物的药敏纸片对分离出的菌株进行了抗生素耐药性测试：阿莫西林、氨苄西林、美罗培南、培氟沙星、链霉素、替卡西林+克拉维酸、磷霉素、头孢布烯、环丙沙星。超过22%的菌株表现出耐药性。交通区域存在大量抗生素耐药菌株，这清楚地表明接触土壤和灰尘会带来很高的健康风险。
