Impacts of Flood Damage on Airborne Bacteria and Fungi in Homes after the 2013 Colorado Front Range Flood

Abstract: Flood-damaged homes typically have elevated microbial loads, and their occupants have an increased incidence of allergies, asthma, and other respiratory ailments, yet the microbial communities in these homes remain under-studied. Using culture-independent approaches, we characterized bacterial and fungal communities in homes in Boulder, CO, USA 2-3 months after the historic September, 2013 flooding event. We collected passive air samples from basements in 50 homes (36 flood-damaged, 14 non-flooded), and we seq… Show more

“…For details on the proportional abundances of these OTUs in male vs. female-occupied rooms, see Figure S1 OTU number Taxonomic Table S1) between female and male rooms. Preliminary evidence suggests that HVAC filters may represent another, relatively lowcost, option for longer-term investigations of airborne microbial communities (Emerson et al, 2015;Noris et al, 2011). Significantly different groups are labeled with an asterisk 2015a).…”

“…DNA extracted from the passive samplers was used for qPCR analyses following the method described in Emerson et al (2015) so we could also assess variation in the amounts of bacteria and fungi recovered in the air of the sampled dormitory rooms. For these analyses, we only focused on the passive samplers as it would have been difficult to extract DNA from the HVAC filters in a manner suitable for quantitative analyses of fungal and bacterial loads.…”

“…Samples were analyzed for microeukayotes and bacteria. Quantitative PCR of bacteria and fungal DNA equivalents were obtained following Emerson et al, 2015. Co-occurrence network analyses preformed on microeukaryotes and bacteria sequences were obtained within samples (N = 19).…”

“…Non-human occupants, including dogs [3,21,22] and household insects [23], can also influence the types of microbes found inside homes. Likewise, there is evidence that the types of bacteria and fungi found inside homes can be affected by differences in ventilation, building design, the environmental characteristics found within buildings [20,22,[24][25][26][27][28] or prior water damage from flooding [29]. If we consider a home to be a microbial ecosystem, the geographical location of a home should also be important in structuring the types of bacteria or fungi found inside the home, just as geography has been known for many decades to structure plant and animal communities across and within continents [30].…”
