Researchers have revealed how polymyxins, crucial last-resort antibiotics, break down bacterial armor by forcing cells to overproduce and shed it. Astonishingly, the drugs only kill bacteria when they ...

Our bodies are a constant battlefield between pathogens and our immune system. But beyond this battle, there’s a larger war being fought between humans and drug-resistant bacteria. When antibiotics ...

Scientists have released new images showing, in incredible detail, antibiotics defeating disease-causing bacteria by piercing the microbes' membranes and infiltrating their innards. The antibiotics, ...

For the first time, researchers have been able to take a series of 3D images of a large section from a medicine-synthesizing enzymes in action. The researchers believe that the images they have ...

Physicians have relied on a class of antibiotics called polymyxins to fight potentially life-threatening Gram-negative bacterial infections for more than 80 years. These drugs are typically reserved ...

This immunofluorescence picture shows an arrested, mature malaria parasite inside its first host cell in the human body, a liver cell. Despite antibiotic prophylaxis a sporozoite enters a liver cell ...

Taking clear pictures of megaenzymes isn’t easy. But it’s definitely worth it. These proteins play an active role in creating many common antibiotics. They are in constant motion, with sections that ...

This electron micrograph shows a Plasmodium sporozoite, the infectious stage transmitted upon a mosquito bite. Antibiotic prophylaxis arrests the parasite life cycle only after maturation of parasite ...
