What Is Pseudomonas Putida?
Gram-negative bacilli, some strains are oval-shaped, Trichomonas unicellular, lively and active. Obligate aerobic, the optimal growth temperature is 25 ° C ~ 30 ° C, 42 ° C does not grow, 4 ° C grows indefinitely, the colonies are similar to Pseudomonas aeruginosa, but only produce fluorescein (purine) and do not produce pyocyanin Therefore, it can be distinguished from Pseudomonas aeruginosa, and its stale culture has a fishy smell.
Pseudomonas putida
discuss- Chinese name
- Pseudomonas putida
- Foreign name
- Pseudomonas putida

- 25 ~ 30
- Attributes
- A pathogen of fish
- Gram-negative bacilli, some strains are oval-shaped, Trichomonas unicellular, lively and active. Obligate aerobic, the optimal growth temperature is 25 ° C ~ 30 ° C, 42 ° C does not grow, 4 ° C grows indefinitely, the colonies are similar to Pseudomonas aeruginosa, but only produce fluorescein (purine) and do not produce pyocyanin Therefore, it can be distinguished from Pseudomonas aeruginosa, and its stale culture has a fishy smell.
- Macular disease, which is common in twin mushrooms, is one of its main pathogenic factors and is more harmful.
- Clinical significance
- Pseudomonas putida ( Pseudomonas putida ) is a pathogenic bacterium in fish. It is often detected in spoiled fish. It can be used as the normal flora of the human pharynx and is a rare conditional pathogen in humans. Occasionally from the human urethra Infections, skin infections, and osteomyelitis were isolated, and the secretions were fishy.
- Microbiological test
- Different from other Pseudomonas in identification, it only produces fluorescein and does not produce pyocyanin, and it can be distinguished from Pseudomonas aeruginosa if it does not grow at 42 ° C; it does not liquefy gelatin, does not produce lecithin, and is on old culture It has a fishy smell, which is different from Pseudomonas fluorescens.
