Altitude-associated trends in bacterial communities in ultrahigh-altitude residences
Background: Indoor bacterial communities may change with altitude because their major contributors, outdoor bacterial communities, vary with altitude. People’s health effects from bacteria inhalation exposure can also vary with altitude because human respiratory physiology changes with oxygen conten...

| description | Background: Indoor bacterial communities may change with altitude because their major contributors, outdoor bacterial communities, vary with altitude. People’s health effects from bacteria inhalation exposure can also vary with altitude because human respiratory physiology changes with oxygen content in air. Accordingly, adjusting indoor bacterial communities may help to acclimate newcomers from low-altitude environments to ultrahigh-altitude environments. To lay the groundwork for further research, we aimed to first elucidate the bacterial communities in ultrahigh-altitude residences and the effects of altitude on these communities. We collected 187 environmental samples from residential communities at ultrahigh altitudes of 3811–4651 m in Ngari, China and sequenced bacterial 16S rRNA genes. Results: On one hand, when abundant genera in ultrahigh-altitude residences and those reported by previous studies on low-altitude residences were compared, nine genera were shared, whereas other five genera were abundant only at ultrahigh altitudes. On the other hand, when the bacterial communities of residences at different ultrahigh altitudes were further compared, the bacterial composition in indoor surface samples varied significantly with altitude. The relative abundance of five bacterial genera in indoor air samples and 10 genera and three phyla in indoor surface samples varied monotonically with altitude. Conclusions: Altitude may be a long-neglected factor that shapes residential bacterial communities and thus warrants attention. |
