Infants with severe RSV infections have an increased likelihood of developing childhood asthma.
The researchers fed mice house dust from homes with dogs. They then exposed these mice to RSV and found that the mice did not show symptoms of infection -- airway inflammation and increased mucus production. They also compared the intestinal bacteria of dust-fed mice to mice that hadn't been fed dust and found differences in the types of bacteria living in the GI tract. These differences were seen whether or not the non-dust fed mice had been exposed to RSV.
