Scientists use metagenomics to explore the viral community inhabiting the human body.

A new understanding of one enzyme’s role in assembling a key macromolecule in the bacterial cell wall takes a step toward overcoming antibiotic resistance. 

A bacterial inhibitor enhances conventional antibiotics by killing Staphylococcus aureus and stopping a communication system in Pseudomonas aeruginosa.

Researchers simultaneously increased the potency of a cancer drug while reducing both the required dose and the side effects, all by using a surprising new drug delivery vehicle: bacteria.

Gut bacteria tailored to a child’s diet may help treat malnutrition.

Antibiotic resistance is on the rise and scientists are on the lookout for new therapeutics for treating human pathogens. One promising new venture repurposes antimalarial drugs to treat patients with chronic lung diseases such as cystic fibrosis.

People with COVID-19 sometimes lose their sense of smell. But a clinical researcher has a possible solution: the patient’s own blood.

Nanosyringes produced by some bacterial species naturally inject proteins into eukaryotic cells, paving a new frontier for biologic drug delivery.

A once fringe theory that viral and bacterial infections trigger the neuroinflammation and cognitive decline associated with Alzheimer’s disease is gaining traction. If it proves true, available antimicrobials could be a long sought-after treatment for this neurodegenerative disease.

Researchers face more obstacles studying the lung microbiome than the gut microbiome. One big hurdle is collecting lung samples. In a new study, researchers used an invasive technique to collect fluid from children’s lungs and discovered how the lung’s microbial makeup affects stem cell transplant outcomes.
