Air Pollution, Early Life Microbiome, and Development

Air Pollution, Early Life Microbiome, and Development SUMMARY: This is a short review of how environmental factors during pregnancy could possibly affect the baby’s development after birth. Effects include being more prone to allergies, obesity, and autism. Many of the results turned out to be inconclusive. The authors give the following reasons: gut microbiota changes… Continue reading Air Pollution, Early Life Microbiome, and Development

Long-term Impacts of Antibiotic Exposure on the Human Intestinal Microbiota

Long-term impacts of antibiotic exposure on the human intestinal microbiota SUMMARY: This review looked the long-term effects of taking antibiotics. If one is looking at the microbiota as a whole, the effects seem to be short term (a few months); however, if one looks at the population of specific species of bacteria, the numbers don’t… Continue reading Long-term Impacts of Antibiotic Exposure on the Human Intestinal Microbiota

B-GOS Prebiotic and Its Affect on Gut Bacteria

In vitro fermentation of B-GOS: impact on faecal bacterial populations and metabolic activity in autistic and non-autistic children SUMMARY: B-GOS stands for galactooligosaccharide and it is a prebiotic. In this experiment, B-GOS was fed to the fecal microbiota of children with and without autism, in vitro. Results showed that this prebiotic increased the number of… Continue reading B-GOS Prebiotic and Its Affect on Gut Bacteria

Gut Bacteria and Parkinson’s

Gut Microbiota Regulate Motor Deficits and Neuroinflammation in a Model of Parkinson’s Disease SUMMARY: This study looked at whether or not gut bacteria could cause symptoms of Parkinson’s. A protein called α-Syn collects and clumps together in the brain, causing the symptoms and affecting the amount of dopamine that is released. There are 8 sections… Continue reading Gut Bacteria and Parkinson’s

Prebiotic Intervention for Children with Autism

A prebiotic intervention study in children with autism spectrum disorders (ASDs) SUMMARY: This study tested the effects of diet and prebiotic on children with autism. The exclusion diet was a gluten-free, casein-free diet and the prebiotic was a galactooligosaccharide that selects for beneficial bacteria in the gut. The study found that the combination of the… Continue reading Prebiotic Intervention for Children with Autism

How the Microbiome Can Change Brain Development

Early Disruption of the Microbiome Leading to Decreased Antioxidant Capacity and Epigenetic Changes: Implications for the Rise in Autism SUMMARY: This is a rather long, but very interesting, article about all the ways gut microbiome can be disrupted. The products of the the gut microbiome can affect brain development, but the article also focuses on… Continue reading How the Microbiome Can Change Brain Development
