The findings suggest that artificial intelligence can help uncover new antibiotics, opening the way for new approaches to antibiotic discovery. The work also offers an open-access resource for antibiotic developers.

New antibiotic kills harmful bacteria while sparing the gut microbiota

The findings of a recent study may inform the development of antibiotics that kill harmful bacteria and not beneficial ones.

Gut microbiota may shape a newborn’s immune system through serotonin production

The findings of a recent study suggest that the infant microbiota produces neurotransmitters that are required for the development of the immune system.

Gut fungi may be linked to inflammation in severe COVID

The findings of a recent study suggest that mycobiota changes during a SARS-CoV-2 infection could contribute to inflammation associated with severe COVID.

Study reveals the microbiota of people with genetic immune deficiency

A recent study analyzed microbial colonization in people with RAG deficiency to shed light on the effects of secondary immunodeficiencies.

How Akkermansia and Lactobacillus plantarum could revolutionize treatment for Lupus through immune regulation

This study demonstrated fundamental mechanisms through which A. muciniphila and L. plantarum modify the gut microbiota and control immune responses in the SLE mouse model.
