Comparison of culturable antibiotic-resistant bacteria in polluted and non-polluted air in Beijing, China.

ABSTRACT: BACKGROUND:Air pollution has been a serious health issue in Beijing for years. Airborne antibiotic-resistant bacteria could be a potential health crisis as reserve of antibiotic resistance transmission in environment. The composition and antibiotic resistance pattern of culturable bacterial community and how these are affected by air pollution remain unclear. OBJECTIVES:This study aimed to compare the compositions and antibiotic resistance patterns of culturable bacteria in polluted and non-polluted weather conditions in Beijing. METHODS:Air samples were collected indoors and outdoors during polluted and non-polluted weather using six-stage Andersen Samplers. For each isolated bacterium, the 16S ribosomal RNA gene was amplified, sequenced, and blasted against the National Center for Biotechnology Information database Antibiotic resistance was conducted by antimicrobial susceptibility testing. RESULTS:Bacterial concentration in polluted weather was significantly higher than in non-polluted weather, both indoors and outdoors (P?
