Скачать или смотреть Colony morphology of Citrobacter freundii on CLED Agar

Citrobacter freundii is a type of bacteria that can be cultured on various types of agar, including CLED (Cysteine Lactose Electrolyte-Deficient) Agar. CLED Agar is a differential medium commonly used for the isolation and differentiation of urinary bacteria. Here's a general description of what you might observe in terms of colony morphology when culturing Citrobacter freundii on CLED Agar:

Colony Shape:

Citrobacter freundii colonies on CLED Agar are typically round or circular in shape.
Colony Size:

The size of the colonies can vary, but they are often medium-sized.
Color:

Citrobacter freundii colonies on CLED Agar may appear pale or colorless.
Opacity:

The colonies might have a translucent or opaque appearance.
Surface:

The colonies may have a smooth or slightly irregular surface.
Texture:

The texture could be mucoid or dry, depending on the specific strain.
Lactose Fermentation:

Citrobacter freundii is capable of fermenting lactose. On CLED Agar, lactose fermenters produce acid, causing a change in pH that is detected by the pH indicator in the medium. This can lead to a color change in the colonies. Citrobacter freundii colonies that ferment lactose may appear yellow due to acid production.
It's important to note that variations in colony morphology can occur due to differences in strains of Citrobacter freundii or variations in laboratory conditions. For accurate identification and characterization, additional biochemical tests, such as Triple Sugar Iron (TSI) agar or biochemical profiling, may be required. Always follow laboratory protocols and consult relevant microbiological references for precise information.
