Infants who lack certain types of gut bacteria in the first few months of life may be at increased risk for asthma when they’re older, a new study from Canada suggests.
In the study, researchers examined the gut bacteria of more than 300 infants when they were 3 months old. Those who had low levels of four specific types of gut bacteria were much more likely to be diagnosed with asthma at age 3 than were infants who had normal levels of these gut bacteria.
The four bacteria are Faecalibacterium, Lachnospira, Veillonella and Rothia, which the researchers combined into the acronym FLVR.
