Differential clustering of bacterial groups is observed with ME exposures. β-diversity calculations using (A) unweighted and (B) weighted analyses. Each circle is representative of one animal in each of the groups of C57Bl/6 mice placed either on regular chow (LF) or a high-fat (HF) diet and exposed to either filtered air (FA) or whole-body inhalation to a mixture of gasoline and diesel engine exhaust (ME: 30 μg PM/m3 gasoline engine emissions + 70 μg PM/m3 diesel engine) for 6 h/d, 7 d/wk for a period of 30 days.
