Study Notes
Pseudomonas Overview
- Pseudomonas belongs to the family Pseudomonadaceae, which is characterized by rod-shaped bacteria.
- Pseudomonas aeruginosa grows optimally at a temperature of 37°C (98.6°F), which aligns with human body temperature.
Pigments of Pseudomonas
- When Pseudomonas aeruginosa combines pyoverdine (a green pigment) and pyocyanin (a blue pigment), it produces a distinctive blue-green pigment.
- Pseudomonas fluorescens produces the pigment fluorescein, known for its bright yellow-green color.
Characteristics and Requirements
- Pseudomonas aeruginosa is known for its opportunistic pathogenicity, ability to thrive in diverse environments, and resistance to antibiotics.
- Pseudomonas bacteria have minimal nutritional requirements and can utilize a wide array of organic compounds, often acting as saprophytes.
Pathogenicity and Motility
- The most significant pathogenic organism within the genus Pseudomonas is Pseudomonas aeruginosa, commonly linked to infections in immunocompromised patients.
- Pseudomonas bacteria are motile due to the presence of polar flagella, enabling rapid movement.
Additional Features
- The characteristic odor associated with Pseudomonas bacteria is often described as sweet or fruity, attributed to the volatile organic compounds they produce.
