Abundance and diversity of antibiotic resistance genes possibly released to ambient air by experiments in biology laboratories

Antibiotic resistance genes (ARG) have been considered as a global emerging threat to public health systems. As special locations where both antibiotics and ARGs are directly used, biology laboratories poorly studied but potential important emission sources not only the environmental stress is strong also obtaining much easier comparing other well hot spots including farms, hospitals, wastewater treatment plants landfills used or discharged. Therefore, in this study, 11 Swiss working on different fields located city center, suburb rural area were reveal abundance diversity of airborne them their surrounding areas with Colony-forming units (CFU) cultivation quantitative Polymerase Chain Reaction (qPCR). Most did discharge significant amounts varieties cultivable bacteria via air. No correlation was found between number CFUs 16S rRNA, two clusters correlated ARGs, animal husbandry related cluster, hospital cluster identified study. Although most may be wide variety which abundant aadA1 eukaryocytes need furtherly make sure if they risks for researchers.
