Difference Between Pseudomonas aeruginosa and Pseudomonas fluorescens

Thekey differencebetween假单胞菌铜绿和假单胞菌fluorescensis that theP.铜绿is an opportunistic humanpathogenwhile thePfluorescensis not a human pathogen.更明确地说,P.铜绿是植物和动物在内的病原体，包括人类Pfluorescenceis a plant growth promoting bacterial species.Another important difference between假单胞菌铜绿和假单胞菌fluorescensis that theP铜绿has the ability to grow even at 42°C.

假单胞菌是一个细菌属，包括gram-negative, rod-shaped and polar flagellated bacteria. They are有氧细菌是非棘突，过氧化氢酶阳性和氧化酶阳性的。此外，该属有许多物种P.铜绿,Pfluorescens,P. Putida,Psyringae,etc.

What is假单胞菌Aeruginosa?

P.铜绿是假单胞菌属的细菌。这是一种革兰氏阴性棒状细菌，具有极地鞭毛。该细菌存在于土壤，水，皮肤和大多数人造环境中。如认可, P. aeruginosais a disease-causing pathogen of plants and animals. Furthermore, it serves as an opportunistic human pathogen that has the property of multidrug resistance. SinceP.铜绿has antibiotic resistance ability; it is responsible for serious illnesses of hospital-acquired infections such as ventilator-associated pneumonia and various sepsis syndromes.

It is difficult to cure diseases caused byP.铜绿because this pathogen is resistant to most of the antibiotics. However, compared to other pathogenic bacteria strains,P.铜绿is not an extremely virulent pathogen. It also has the ability to form biofilms as it is capable of colonizing extensively on surfaces.

什么是假单胞菌荧光症？

Pflourescens是another bacterial species of the genus Pseudomonas. It is not a pathogen, but a plant growth promoting bacterium found mostly in the soil. Therefore, it hardly causes diseases to human.

Pfluorescensexists in a wide range of habitats including soil, rhizospheres, and surfaces of plants, nonsterile pharmaceuticals, showerheads, and even indoor wall surfaces. As recognized, it is an environmentally important bacterium since it is capable of promoting plant health via secreting antimicrobials, secondary metabolites, sidarophores, etc.

之间有什么相似之处假单胞菌铜绿和假单胞菌fluorescens?

• Pfl铜绿和Pfluorescens是革兰氏阴性细菌。
• 它们都是非棘手形成的细菌。
• Also, both are aerobic bacteria.
• 此外，它们都是棒状细菌。
• 鞭毛is in both.
• Both are flagellated and motile.

What is the Difference Between假单胞菌铜绿和假单胞菌fluorescens?

假单胞菌铜绿vs假单胞菌
P.铜绿is a bacterial species of the genus Pseudomonas, and it is a plant and animal pathogen.	Pfluorescens是假单胞菌属的细菌种类，它是促进细菌的植物生长。
Disease-Causing Ability
Well established as a pathogen	不被描述为导致严重疾病的病原体
鞭毛
有一个鞭毛	Has multiple flagella
Growth
The growth is enhanced at 25°C to 37°C but it can grow at 42°C as well, which is a factor that distinguishes it from other假单胞菌	The optimal temperature for growth is 25-30°C. However, the biofilm forms at 37°C
Virulency
一个致命的物种	不是强大的物种
Oxygen Requirement
有氧，但有时变成facultative anaerobic	Obligate aerobe
产生次生代谢物
Does not produce secondary metabolites that are important for plant growth promotion	产生抗疾病和生物防治剂的二级代谢产物
Rapid Nitrate Test
Shows positive for rapid nitrate test	Shows negative for the rapid nitrate test
Sensitivity to Low Levels of Kanamycin and Resistant to Carbenicillin
Low sensitive to low levels of kanamycin and susceptible to carbenicillin	对低水平的卡纳霉素非常敏感，对卡替霉素的抗性

概括– Pseudomonas aeruginosa vs Pseudomonas fluorescens

P.铜绿和Pfluorescensare two bacterial species of the genus Pseudomonas.P.铜绿is a pathogen causing disease in plants and animals including human.Pfluorescensis a non-pathogenic species, and it can promote plant growth and also has biocontrolling properties. This is the difference betweenP.铜绿和Pfluorescens。更远，P.铜绿有一个极地鞭毛Pfluorescens是多弹性的。
