Conclusions PD0325901 price Fecal colonisation at age 3 weeks with either a Bacteroides fragilis subgroup or a Clostridium coccoides subcluster XIVa species is an early indicator of possible asthma later in life. These findings need to be confirmed in a new longitudinal follow-up study. The effect of pre- and probiotics on the intestinal colonization with Clostridium and Bacteroides requires further attention in future trials for the prevention of asthma in infants and children.
