It is already known that a reduction in gut microbial richness is the hallmark change of human immunodeficiency virus (HIV) infection, but how this dysbiosis is established in the HIV-exposed uninfected infant is poorly understood. A recent cross-sectional study, led by Dr. Grace M. Aldrovandi from the Children’s Hospital Los Angeles in Los Angeles (USA), suggests that perturbations in the infant gut microbiome may explain the greater risk of morbidity and mortality in uninfected babies born to HIV-positive mothers.

A recent review, published by Dr. Thierry Hennet and Dr. Lubor Borsig from the Department of Physiology and Centre for Integrative Human Physiology at University of Zürich (Switzerland), describes the up-to-date data regarding the unique biology of human breast milk as a multifunctional fluid.

Childhood undernutrition affects millions of children worldwide and has long-term severe effects, which include stunted growth and impaired cognitive development, among others. A recent study, led by Dr. Jeffrey Gordon from the Centre for Genome Sciences and Systems Biology at Washington University School of Medicine in St. Louis (USA), found that gut bacteria could be considered a useful tool for ameliorating the harmful side effects of malnutrition in mice.

In this study, researchers characterized the gut microbiota of breastfeeding mothers after collecting fecal samples from 2 days to 6 months postpartum. They found that the women's gut bacterial communities were similar to those found in other adults; the gut

One of the probiotic strains was recovered in the stool of the children at 10 days and 3 months of age, but there were no differences between the gut microbiota of the children in the control group and those in the probiotic group at 1 and 2 years of age.
