Genera of Enterobacteriaceae

Examples of genera that are part of the Enterobacteriaceae family include Escherichia, Salmonella, Shigella, Klebsiella, Proteus, and Enterobacter.

Lactose Fermenters

Genera of Enterobacteriaceae that are part of the lactose fermenters group include Escherichia and Klebsiella.

Pathogenic Genera

Genera of Enterobacteriaceae that are regularly pathogenic for humans include Escherichia, Salmonella, and Shigella.

Common Antigen

The common antigen shared by the genera of Enterobacteriaceae is the lipopolysaccharide (LPS) O antigen.

Non-Lactose Fermenters

Examples of Enterobacteriaceae genera that are lactose non-fermenters include Salmonella and Shigella.
