Farm-like indoor microbiota may protect children from asthma also in urban homes

ScienceDaily | 6/17/2019 | Staff
"We now discovered that the presence of farm-like microbiota in an early-life home seemed to protect from asthma also in urban homes. The effect was not based on the presence of large number of different microbial species but rather differences in the relative abundance of certain bacterial groups," says Pirkka Kirjavainen, Senior Researcher at the Finnish National Institute for Health and Welfare.

The study found that the microbiota in homes protecting from asthma contained a wealth of bacteria typical of the outdoor environment, including bacteria in soil. On the other hand, the proportion of microbes normally occurring in the human respiratory tract and associated with respiratory tract infections was small.

Characteristic - Microbiota - Homes - Abundance - Bacteria

"The key characteristic of microbiota in homes protecting from asthma appears to be large abundance of bacteria which originate from the outdoor environment and are beneficial or harmless to health, relative to bacteria that are a potential threat to health," Kirjavainen comments.

In urban homes, factors that increased the farm-like features in...
