ABSTRACT Gastrointestinal disturbance is frequently reported for individuals with autism. We used quantitative real-time PCR analysis to quantify fecal bacteria that could influence gastrointestinal health in children with and without autism. Lower relative abundances of Bifidobacteria species and the mucolytic bacterium Akkermansia muciniphila were found in children with autism, the latter suggesting mucus barrier changes.

Human Respiratory and Gut Microbiomes—Do They Really Contribute to Respiratory Health?

Frontiers in Pediatrics (2020)

Juliana Durack C. Christophersen

Human gastrointestinal and respiratory tracts are colonized by diverse polymicrobial communities shortly after birth which are continuously molded by environmental exposure. The development of the resident microbiota in early life is a critical factor in the development of a healthy immune system. Disturbances to the intricate relationship between environmental exposure and maturation of the microbiome have been increasingly identified as an important component of a range of childhood diseases. This review details recent evidence that implicates the contribution of gut and airway microbiome to pediatric respiratory health.
