First, gram-negative bacteria have a thin cell wall that is about 1.5 to 10 nanometers across, whereas gram-positive bacteria have a thick cell wall measuring about 20 to 80 nanometers.

When exposed to antibiotics, approximately one out of every 10 8 -10 9 bacteria develops resistance due to spontaneous ...

What Is Quorum Sensing? Individual bacteria use quorum sensing to detect and respond to changes in cell density as a coordinated group. For example, the first reported evidence of quorum sensing was ...

Not all cases of non-HACEK Gram-negative bacterial endocarditis necessarily require surgical intervention. Indications for surgical intervention in patients with Gram-negative endocarditis are ...

Using this approach, they have uncovered that bacteria assemble their nanoweapons in response to cell envelope damage and rapidly strike back with high precision. Some bacteria deploy tiny ...
