Mycoplasma pneumoniae with pathogenic genes replaced by biofilm-degrading ones enhance survival in a mouse model of ventilator-associated pneumonia.

Studies are finding that a single course of antibiotics alters the gut microbiomes of healthy volunteers—and that it can take months or even years to recover the original species composition.

Use of the drugs in children under the age of two was associated with lower antibody levels after the jabs—perhaps, researchers suggest, due to microbiome alterations.

Making specific alterations to the bacterial population in a rat’s lungs either better protects the animals against multiple sclerosis–like symptoms or makes them more vulnerable, a study finds—the first demonstration of a lung-brain axis.

A new study has identified a molecular tradeoff between growth and immunity in moths in response to the administration of subtherapeutic doses of antibiotics, a common practice in animal husbandry.

Levels of pharmaceuticals considered unsafe for aquatic organisms were found at more than one-quarter of sampling sites.

The health of the microbial community is associated with COVID-19 severity, but it’s not yet clear if the relationship is causal.

The UCSF microbiologist pioneered investigations into the deadly disease starting in the late 1960s that have led to the near eradication of trachoma, a chlamydia-related eye infection.

Researchers could one day use the method to deliver antibiotics to topical wounds infected by hard-to-treat masses of bacteria.

Researchers used a machine-learning platform to test more than 100 million molecules for antibacterial activity.

Metabolic disrupters, phages, and other approaches are going to be needed to treat the broadest possible range of patients infected by bacterial pathogens resistant to multiple drugs.

Bacteria grow and divide in microfluidic channels.

The Tufts University biologist and physician sounded the alarm on the effects of antibiotic use in animals.
