Asthma is a common condition and is characterized by shortness of breath, wheezing and difficulty in breathing in.  Whether bacterias may be protective of the development of asthma is not known.


To investigate whether gut bacteria may correlate with asthma development in children.


Researches from the University of British Columbia in Vancouver, Canada, looked for four types of bacteria (Faecalibacterium, Lachnospira, Veillonella, and Rothia) in stool samples of 319 infants at 3 months of age.

Of these, 22 children with low levels of these bacteria at age 3 months also had low levels at age 1 year and were at the highest risk of developing asthma, and eight have been diagnosed with it so far, the experts said.


These results enhance the potential for future bacterial diagnostics and therapies, potentially in the form of probiotics, to prevent the development of diseases such as asthma and other related allergic diseases in children.
