Babies' exposure to bacteria could prevent asthma
Being exposed to 'good bacteria' could prevent children from developing asthma.
Scientists reported that children lacking four types of bacteria in their bodies at three months old were at high risk of developing asthma by the time they were three. Eight of 22 of the children with less of this bacteria in their gut developed asthma later in life, and the rest were considered high risk.
The study, published in Science Translational Medicine, suggests a baby's first 100 days of a baby's life are crucial to their developing immune systems.
The children were tested for wheezing and skin allergies for their asthma risk assessment, and further tests on baby mice showed that the four bacteria reduced inflammation in their airways.
Asthma is caused by airways that are more sensitive to irritation and inflammation.
The four bacteria together could form the basis of a cure for asthma – great news considering one in every 11 children in the UK has asthma, and cases have been soaring for the last 60 years.
