It was long thought that when the membrane of a cell lost its integrity and broke down, the cell would die; cells cannot survive without a cell wall. Many antibiotics target the cell wall of bacteria, ...

Bacteria are evolving to elude our drugs at an alarming rate, so much so that the UN has declared antibiotic resistance a global health emergency with the expectation that it could kill millions upon ...

For bacteria, the first line of defense is the cell wall, which keeps toxins such as antibiotics out. Now, researchers have discovered a key mechanism that bacteria use to build their cell walls, ...

A transporter which some bacteria use to recycle fragments of their cell wall has been discovered by researchers at Umeå university, Sweden. They found that the transporter controls resistance to ...

Researchers at Umeå University in Sweden published a study “Breaking barriers: pCF10 type 4 secretion system relies on a self-regulating muramidase to modulate the cell wall” in mBIO that describes ...

In tight spaces that trap most microbes, one bacterium keeps moving by reconfiguring how it swims, revealing a new biological ...

The bacterial cell wall must be constantly remodeled in order to grow and divide. This involves the close coordination of lytic enzymes and peptidoglycan synthesis. Researchers led by Martin ...

Each year, bacterial infections are responsible for roughly 7.7 million deaths worldwide, with this problem further exacerbated by rising antibiotic resistance. Not only are wound infections ...

Textbook images show peptidoglycan as straight and ordered. The biopolymer peptidoglycan that makes up bacterial cell walls was always assumed to be highly ordered. Textbook images like the one below ...
