A recent randomized double-blind placebo-controlled trial, led by Dr. Ellen Blaak from the Department of Human Biology at Maastricht University Medical Centre in Maastricht (The Netherlands), has found that a 7-day antibiotic treatment does not affect host metabolism in obese humans in the short term, despite profound changes in gut microbial diversity and composition.

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.
