Researchers at Bar-Ilan University have identified a potential link between autism spectrum disorder (ASD) and the composition of the gut microbiome. The study found significant differences in the diversity of the gut microbiome in individuals with ASD compared to those without. Specifically, they identified an increase in alpha diversity and a rise in the abundance of the phylum Bacteroidetes and the genus Bacteroides in individuals with ASD. The researchers also conducted experiments on newborn mice, finding that those treated with Bacteroides fragilis exhibited social behavior dysfunction and increased repetitive behaviors. The study's lead researcher, Prof. Evan Elliott, believes that an overabundance of Bacteroides, particularly in early life, may have functional consequences for individuals with ASD.
