Overview

A team of researchers from the University of B.C. has uncovered extraordinary connections between micronutrient deficiencies and the composition of gut microbiomes in early life that could help explain why resistance to antibiotics has been rising across the globe.

The team primarily investigated how deficiencies in crucial micronutrients such as vitamin A, B12, folate, iron, and zinc affected the community of bacteria, viruses, fungi, and other microbes that live in the digestive system.

The study, published this week in Nature Microbiology, offers critical insights into the far-reaching consequences of micronutrient deficiencies in early life. It underscores the need for comprehensive strategies to address undernutrition and its ripple effects on health. Addressing micronutrient deficiencies is about more than overcoming malnutrition, it may also be a critical step in fighting the global scourge of antibiotic resistance.

They discovered that these deficiencies led to significant shifts in the gut microbiome of mice most notably an alarming expansion of bacteria and fungi known to be opportunistic pathogens. Importantly, mice with micronutrient deficiencies also exhibited a higher enrichment of genes that have been linked to antibiotic resistance.

“Our findings are particularly concerning as these children are often prescribed antibiotics for malnutrition-related illnesses. Ironically, their gut microbiome may be primed for antibiotic resistance due to the underlying micronutrient deficiencies." They concluded.
