Friendly bacteria and antibiotics

In humans, the intestinal microbiota aids metabolic and immunological development among other functions. New research suggests that exposure to antibiotic drugs in early life may disrupt the gut microbiome, with potentially far-reaching consequences.

In the study, mice were given amoxicillin (a beta-lactam), tylosin (a macrolide) or alternating courses of the two antibiotics, at doses and frequencies representative of those used in young children. Significantly, antibiotic-treated mice gained more weight and developed larger bones compared with control mice. DNA sequencing revealed that antibiotics disrupted the gut microbiome in terms of composition, diversity and maturation rate; they also altered the relative numbers of microbial genes linked with specific metabolic functions.

“These observations raise the possibility that early-life antibiotic treatment may influence metabolic phenotypes in humans,” say the researchers in Nature Communications (online, 30 June 2015).
