Q

Lipopolysaccharide

A

contains O-antigen - increases the negative charge of cells, provides structural integrity and protects from different chemicals.
(Lipid A + A/B antigens)

Q

Secretion of toxins

A

A prolific producer of exoproducts, secretion pathways export from the cytoplasm to the external environment, 5 different secretion systems.
