This is notably expressed through the classification into Gram positive and Gram negative bacteria.

Acetobacter aceti is a Gram negative bacterium that moves using its peritrichous flagella.

Gram negative bacteria have two membranes, thus making secretion topologically more complex.

There are at least six specialized secretion systems in Gram negative bacteria.

The resulting filamentous phages can infect Gram negative bacteria once again to produce phage libraries.

Pseudomonas pseudoalcaligenes is an aerobic, Gram negative soil bacterium that was first isolated from swimming pool water.

Phenotypically, B. kururiensis is a Gram negative bacterium with an oval cell morphology.

These mice were also found to be hypersusceptible to infection by Gram negative bacteria.

Introduction Endotoxin is a major component of the cell wall of Gram negative bacteria.

Gram negative bacteria trigger human intestinal mast cells for histamine and cytokine production.
