What type of colonies does Pseudomonas stutzeri produce?

• A. Dry and wrinkled colonies that are tough and adhere to media
• B. Mucoid colonies that are smooth and slippery
• C. Flat and shiny colonies
• D. Colony types resembling Stenotrophomonas maltophilia

Answer: (A)

Pseudomonas stutzeri is known for producing dry and wrinkled colonies that have a tough consistency and adhere well to the culture media. This characteristic is significant as it reflects its ability to thrive in various environments, particularly where it may face stressors, contributing to its resilience as a bacterium. The appearance of colonies being dry and wrinkled also aligns with the typical morphological features associated with Pseudomonas species, aiding in differentiation from other bacteria based on colony morphology in laboratory settings. The adherence of these colonies to the media hints at the presence of biofilm-forming capabilities, which is common among bacteria within the Pseudomonas genus, contributing to their pathogenic potential and environmental persistence.
