EFFECTS OF BACTERIA ON AUTISTIC LIKE BEHAVIOUR

27th May 2020

In this study, scientists have shown the protective capabilities of good bacteria to prevent autistic like symptoms.

The pups of mice stressed during pregnancy and given a heat treated “good” bacteria did not show autistic behaviours unlike the untreated group.

Having a healthy microbiome at the start of life is so important to long term health and well-being.

RESEARCH ON TRAINSITION OF MICROBES FROM MOTHER TO INFANT

10th May  2020

“Researchers at the University of Alabama at Birmingham now have used their microbiome “fingerprint” method to report that an individualized mosaic of microbial strains is transmitted to the infant gut microbiome from a mother giving birth through vaginal delivery. They detailed this transmission by analyzing existing metagenomic databases of fecal samples from mother-infant pairs, as well as analyzing mouse dam and pup transmission in a germ-free, or gnotobiotic, mouse model at UAB, where the dams were inoculated with human fecal microbes. “The results of our analysis demonstrate that multiple strains of maternal microbes — some that are not abundant in the maternal fecal community — can be transmitted during birth to establish a diverse infant gut microbial community,”

INFANTS INTRODUCED EARLY TO SOLID FOODS SHOW GUT BACTERIA CHANGES THAT MAY PORTEND FUTURE HEALTH RISKS

21st April 2020

GUT MICROBIOME SHIFTS MAY EXPLAIN HOW EARLY DIETARY FACTORS BRING LATER HEALTH RISKS

Infants who were started on solid foods at or before three months of age showed changes in the levels of gut bacteria and bacterial byproducts, called short-chain fatty acids, measured in their stool samples, according to a study from researchers at Johns Hopkins Bloomberg School of Public Health.

Prior studies have linked the early introduction of solid foods to a higher chance of being overweight in childhood. The new study, published in BMC Microbiology, suggests that early solid food introduction may predispose infants to being overweight at least in part by altering the gut bacterial population.

“How the early introduction of solid foods would cause the later development of obesity has been unknown, but our findings suggest that disruptions to gut bacteria may be one explanation,” says Noel Mueller, PhD, assistant professor in the Department of Epidemiology at the Bloomberg School.
