A recent study led by Dr. Alex Mira (FISABIO, Spain) and Dr. Maria C. Jenmalm (Linköping University, Sweden) and researchers at IATA-CSIC (Spain) has presented an analysis of a total of 192 faecal samples from 28 healthy children and 20 children developing allergic symptoms at age seven, from when the children were 1 and 12 months of age. It has found that children who develop asthma or allergies later in life have altered immune responses to intestinal bacteria in the gut mucosal environment at an early age.
