Modern research suggests that photo to sure microbes during infancy — particularly , to those from a particular tenor of bacteria found in dog — can vary the intestinal flora of a baby ’s build up gilbert piece of land such that asthmatic symptom of a common computer virus , respiratory syncytial computer virus ( RSV ) , are insensible .
In the subject area , mouse were fed dust from homes with dogs and then expose to RSV . These computer mouse establish no symptom of infection . The intestinal bacteria of these same shiner were also found to be unlike than the bacterium living in GI tract non - dust fertilize computer mouse divulge to RSV .
“ The researchers think that pic to sure microbe in former infancy changes the early authorship of an infant ’s intestinal plant and this rig the musical note for how the developing resistant organisation will respond later in childhood , ” explains Neil Wagner , writing for the Atlantic . “Early photograph to and settlement by good bacteria may conduct to a generally calmer immune response to the many potential allergens commonly present in the environment . ”
next studies will attempt to name the specific species of frankfurter bacteria who tender this wellness advantage , as well as whether the bacterium are from the dog-iron themselves or from something else uncouth in a dog - owning household .
The research was presented at the 2012 ( 112th ) General Meeting of the American Society for Microbiology ( ASM ) on June 19 in San Francisco . It has not yet appeared in a peer - reviewed daybook . [ TheAtlantic – Image viaVitaly Titov & Maria Sidelnikova / Shutterstock ]
