From: Chronic exposure to ambient particulate matter induces gut microbial dysbiosis in a rat COPD model
Effect of particulate matter exposure on community diversity and richness of the lung microbiota. Operational taxonomic units (OTUs) (a) and microbial diversity (Shannon index (b) and Chao 1 index (c)). Composition and relative abundances of bacterial phyla in different groups after 4, 12 and 24 weeks exposure (d-f). Results are expressed as mean ± SD; n = 6 rat. CON, control group; BMF, biomass fuel exposure group; MVE, motor vehicle exhaust exposure group
