Temporal changes in the size resolved fractions of bacterial aerosols in urban and semi-urban residences.

ABSTRACT: Despite the significant amount of time spent in the domestic environment, culture-independent size distribution data of bioaerosols are largely missing. This study investigated the temporal changes in size-resolved bacterial aerosols in urban and semi-urban residential settings. Overall, airborne bacterial taxa identified in both sites were dispersed across particles of various sizes. qPCR analysis showed that outdoors bacteria dominated particles > 8 μm, whilst indoor bacterial loadings were greater with 1-2 μm (winter) and 2-4 μm (summer) ranges. Indoor and outdoor aerosols harboured distinct bacterial communities due to the dominance of human-associated taxa (Staphylococcus, Micrococcus, Corynebacterium) in indoor air. The aerosol microbiome exhibited significant temporal variation, wit
