Urban dust samples were collected in Moscow (Russia) in June 2021. The samples were collected in three functional zones of Moscow (traffic, residential, and recreational) and included air microparticles, leaf dust, and paved dust. Data on the taxonomic composition of bacterial communities were obtained for dust samples, and their functional characteristics were predicted using PICRUSt2 2.5.0 and FAPROTAX 1.8.0 software. The culturable part of the bacterial community was examined for the presence of antibiotic-resistant strains with respect to β-lactams, tetracyclines, amphenicols, and aminoglycosides. The presence of bacteria resistant to ceftazidime, cefepime, and tetracycline was detected in all dust samples. The presence of bacteria resistant to meropenem and amikacin was only observed in the dust collected from leaves in the residential and traffic zones. The overall abundance of cultured antibiotic-resistant bacteria from the total heterotrophs ranged from 0.03% to 1.88%, with the highest percentage observed in dust from the residential zone. Notably, strains resistant to all antibiotics tested were observed in the leaf dust bacterial community.
2021年6月在俄罗斯莫斯科采集了城市灰尘样本。样本采集于莫斯科的三个功能区（交通区、居民区和休闲区），包括空气微粒、树叶灰尘和铺砌地面灰尘。获得了灰尘样本细菌群落的分类组成数据，并使用PICRUSt2 2.5.0和FAPROTAX 1.8.0软件预测了它们的功能特征。检测了细菌群落中可培养部分对β-内酰胺类、四环素类、氯霉素类和氨基糖苷类抗生素耐药菌株的存在情况。在所有灰尘样本中均检测到对头孢他啶、头孢吡肟和四环素耐药的细菌。仅在居民区和交通区树叶上收集的灰尘中观察到对美罗培南和阿米卡星耐药的细菌。培养的抗生素耐药细菌在总异养菌中的总体丰度范围为0.03%至1.88%，在居民区灰尘中观察到的百分比最高。值得注意的是，在树叶灰尘细菌群落中观察到了对所有测试抗生素均耐药的菌株。
