Lecture 9: Order Enterobacterales

Flashcards covering the key characteristics, biochemical properties, and environmental presence of the order Enterobacterales.

Characteristics of Enterobacterales

Ferment glucose, reduce nitrates to nitrites, non-sporulating, anaerobic, oxidase negative, and gram-negative rods.

Ferment glucose

A key characteristic of Enterobacterales indicating their ability to metabolize glucose.

Reduce nitrates to nitrites

A biochemical process important in UTI testing associated with Enterobacterales.

Non-sporulating

Refers to organisms that do not form spores, a characteristic of Enterobacterales.

Anaerobic, oxidase negative

Characteristics of Enterobacterales indicating they do not require oxygen for growth and do not produce cytochrome oxidase.

Gram-negative rods

The cellular morphology of Enterobacterales, which are rod-shaped and do not retain the crystal violet stain used in the Gram staining protocol.

Where are Enterobacterales found?

In the environment, showcasing their widespread presence.
