Pets may contribute to lowering the risk of childhood allergies

This was the conclusion made by Canadian researchers from the University of Alberta, in a study published in the journal Microbiome.


In a study involving 746 infants from the Canadian Healthy Infant Longitudinal Development Study (CHILD) birth cohort, the researchers explored the impact of pet exposure, either during pregnancy or within the first three months after birth, on the composition of infant gut microbiota.


They found that pet exposure, mainly dogs and cats, during pregnancy or the postpartum period up to three months after birth, resulted in a twofold increase in the presence of beneficial gut bacteria:


▶ Ruminococcus

▶ Oscillospira


These bacteria have been associated with lower rates of childhood allergies.


The authors suggest that early-life exposure to household pets may contribute to a decreased risk of childhood metabolic and atopic diseases. Further research is necessary to fully elucidate the impact of household pets on the human microbiome.
