What is the morphology of Enterobacter?
Morphology. Members of the Enterobacteriaceae are bacilli (rod-shaped), and are typically 1–5 μm in length. They typically appear as medium to large-sized grey colonies on blood agar, although some can express pigments. Most have many flagella used to move about, but a few genera are nonmotile.

What causes Enterobacter infection?
– M. – These pathogens are similar to Proteus in all respects except infection of healthy ambulatory hosts is uncommon. – They primarily infect residents of LTCF and less commonly hospitalized patients with indwelling urinary catheters. – Extensive use of polymyxins & tigecycline may select for these genera due to their inherent resistance to these agents.
