From: Agricultural dust derived bacterial extracellular vesicle mediated inflammation is attenuated by DHA

Dust-derived EVs contain DNA from both Gram (+) and Gram (−) bacterial species, as well as viral (bacteriophage) signatures. The 50 most prevalent signatures originated predominantly from Gram (+) bacteria (65%) commonly found in feces, soil, and as part of the normal swine gut flora. Several pathologic species were also identified.
