Particular combinations of bacteria found in dust at day care facilities have been linked to wheezing in young children. Wheezing in young children is often an early sign of asthma. The new research offers some clues as to why attending day care can affect children's lung health that could, in turn, point to measures for lowering the risk of asthma.
Particular combinations of bacteria found in dust at day care facilities have been linked to wheezing in young children in a study presented at the European Respiratory Society International Congress in Milan, Italy. Wheezing in young children is often an early sign of asthma.
The study was presented by Dr Annabelle Bédard, a researcher at Inserm , Paris, France. She said:"We find mixtures of different bacteria and other microbes living everywhere - outside, inside our homes, on our skin and even inside our bodies. These communities of bacteria, known as microbiota, can have beneficial or harmful effects on our health.
The researchers used an adapted vacuum cleaner to collect samples of dust from the floor of 103 different day care settings in the Paris region. They used genetic analysis in the laboratory to identify the different types of bacteria found in each sample.
