Difference Between Pseudomonas Aeruginosa and Enterobacteriaceae

关键的区别——伪monas Aeruginosa vs Enterobacteriaceae

Bacteriaare microorganisms that cause diseases in animals and plants. They are ubiquitous organisms, meaning they are present everywhere. Enterobacteriaceae is a large family ofgram-negative bacteria. It includes rod-shaped, flagellated motile bacteria. This family consists of most common pathogenic bacteria such asE. coli,Shigella,Salmonella,Klebsiella, etc. Pseudomonas aeruginosa is a gram-negative, rod-shaped motile bacterium of the family Pseudomonadaceae and order Pseudomonadales.P. aeruginosais an aerobic bacterium that is known as a common nosocomialpathogen. Thekey differencebetween P. aeruginosa and Enterobacteriaceae is thatP. aeruginosais a bacterial species while Enterobacteriaceae is a family of gram-negative bacteria.

What is Pseudomonas Aeruginosa?

Pseudomonas aeruginosa is a bacterial species that is gram negative and rod-shaped. It causes diseases in plants and animals including humans.P. aeruginosais an obligate aerobic bacterium. It is common as an opportunistic pathogen.P. aeruginosabelongs to family Pseudomonadaceae and order Pseudomonadales.P. aeruginosaproducesexotoxins and endotoxinsthat are powerful infectious agents.

Aeruginosais a very ubiquitous bacterium that is found in all most all the habitats including soil, water, humans, animals, plants, sewage, and hospitals.P. aeruginosais popular as a nosocomial pathogen.P. aeruginosais a multidrug-resistant bacterial species. Hence, it is caused by hospital-acquired infections such aspneumonia,sepsisetc.

什么是肠杆菌科?

Enterobacteriaceae is a large family of grams negative bacteria. It consists of nonpathogenic and pathogenic bacteria. They are found in soil and plants and are colonizers of the gastrointestinal tract of humans and animals. A well known pathogenic bacteria,Shigella,E. coli,Salmonella,Klebsiellabelong to this family. And also this family consists of disease-causing bacteria such asProteus,Enterobacter,Serratia, andCitrobacteretc.

Enterobacteriaceae belongs to the order Enterobacteriales. This family contains rod-shaped bacteria. Since they are gram-negative, they stain in pink colour during thegrams stainingprocedure. Enterobacteriaceae bacteria are mostly facultativeanaerobic or aerobes. They possess flagella and this family contains many motile bacteria. Some bacteria are non-motile. Bacteria in the Enterobacteriaceae are non-spore forming. Many of the Enterobacteriaceae bacteria produce endotoxins that are harmful and cause diseases. Endotoxins are responsible forinflammatoryandvasodilatoryimmune responses in humans when released into the bloodstream.

One of the most popular Enterobacteriaceae bacterium E. coli is a free-living bacterium that causes urinary tract infection and traveler’s diarrhea and is the most common cause of nosocomial bacteremia.

What are the Similarities BetweenPseudomonas Aeruginosaand Enterobacteriaceae?

• Bothaeruginosaand family Enterobacteriaceae are grams negative.
• Bothaeruginosaand family Enterobacteriaceae are rod-shaped bacteria.
• Both types of bacteria stain in pink colour during the grams staining.
• Both types cause pneumonia and diarrhea.
• aeruginosaand Enterobacteriaceae bacteria produce toxins.
• aeruginosaand Enterobacteriaceae are non-spore forming.

What is the Difference BetweenPseudomonas Aeruginosaand Enterobacteriaceae?

Pseudomonas Aeruginosa vs Enterobacteriaceae
Pseudomonas aeruginosais a common gram-negative rod shaped bacterium.	Enterobacteriaceae is a large family of gram-negative bacteria.
Bacterium or Group of Bacteria
Pseudomonas Aeruginosa is a bacterial species.	Enterobacteriaceae is a family of bacteria.
Motility
Pseudomonas Aeruginosa is a motile bacterium.	Enterobacteriaceae bacteria mostly motile. But it contains nonmotile bacteria as well.
Type
Pseudomonas Aeruginosa is an obligate aerobic bacterium.	Enterobacteriaceae bacteria are aerobic or facultative anaerobic.

Summary –Pseudomonas Aeruginosa vs Enterobacteriaceae

Enterobacteriaceae is a large family of gram-negative bacteria that are non-spore forming, rod-shaped, motile and flagellated. This family includes most common disease-causing pathogenic bacteria such asE. coli,Shigella,Salmonellaandklebsiella. Bacteria that belong to this family are aerobic or facultatively anaerobic. Pseadomonas aeruginosa is a gram-negative, rod-shaped flagellated bacterium family Pseudomonadaceae. It is a ubiquitous bacterium present in everywhere. It is known as an opportunistic pathogen that causes nosocomial diseases in immune-compromised people.P. aeruginosais an obligate aerobic bacterium. And it is not forming spores. It produces exotoxins and endotoxins. This is the difference between P. aeruginosa and Enterobacteriaceae.
