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.

Three of these six pathogens are antibiotic-resistant Gram-negative bacteria. Recently, antibacterial drugs against ESBL-producing Gram-negative bacteria accounted for ∼15% (2 out of 13 ...

All patients with suspected Gram-negative endocarditis should undergo transesophageal echocardiography (TEE) to confirm the diagnosis and assess for cardiac complications such as intracardiac ...

Some Pseudomonas species use specialized microscopic membrane devices to fight back against competing bacteria.

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 ...

and the production of the building blocks for membrane phospholipids is precisely regulated to match the rate of cell division. Bacteria control the homeostasis of membrane lipid biophysical ...
