Experiments in mice show that some gut bacteria can absorb toxic PFAS chemicals, allowing animals to expel them through feces.

Gram-negative bacteria show pink or red on staining and have thin walls. They release different toxins and affect the body in different ways. Gram-positive and Gram-negative are types of bacteria.

A living motor made by combining different parts from bacteria is one of the smallest ever built, and could one day power tiny robots. Many types of bacteria are propelled by natural motors that ...

Clostridium perfringens is a spore-forming bacteria that can function without oxygen (anaerobic bacteria). These gram-positive bacteria are typically found in human and animal intestines. Bacteria ...

Most species of bacteria can be broadly divided into two groups, known as gram-positive and gram-negative. These categories ...

Researchers have developed a compound that shows promise against Gram-positive bacteria, such as necrotizing fasciitis.

The compound, designated PS757, represents the first of an entirely new class of GmPcide (gram-positive-icide) antibiotics, and targets Gram-positive bacteria, which can cause drug-resistant staph ...

These fast-spreading infections usually involve multiple types of gram-positive bacteria. Necrotizing fasciitis –or flesh-eating disease–is the best known of these infections.

Importantly, the antibiotic also appeared to leave commensal bacteria alone, since many are gram-positive bacteria that don’t have the Lol complex that lolamicin exploits.

Gram-positive and gram-negative bacteria differ in the composition of their cell walls. Gram-negative bacteria have a double layer of protection, making them more difficult to kill, Muñoz said.
