Antibiotics are drugs used to treat infections caused by bacteria and other microorganisms.

Researchers Use Bacterium’s Own Defenses to Amplify Antibiotic Power

Scientists at St. Jude Children's Research Hospital have found a way to use a bacterium's own drug resistance mechanisms against itself, presenting a potentially safer and more effective way to treat certain antibiotic-resistant infections.

Unexpected Enzyme Strategy Behind Antibiotic Resistance

Researchers at McGill University have identified two enzymes that employ an unprecedented mechanism to provide resistance, thereby introducing a new dimension in the fight against antimicrobial resistance (AMR), which ranks among the top 10 global public health challenges.

Researchers Uncover How Pseudomonas Bacteria Sense and Build Biofilms

The bacterium known as Pseudomonas aeruginosa is an unwelcome visitor in the human body. Serious infections can result when a bunch of these bugs settle together on a surface to form a biofilm - a community of microbes like the slime on spoiled food, but in this case residing inside a person.

Soil DNA Reveals Hundreds of Unknown Bacterial Genomes

Most bacteria cannot be cultured in the lab-and that's been bad news for medicine. Many of our frontline antibiotics originated from microbes, yet as antibiotic resistance spreads and drug pipelines run dry, the soil beneath our feet has a vast hidden reservoir of untapped lifesaving compounds.
