What is E. Coli?

E. coliis a gram-negative, rod-shaped, facultative anaerobic bacterium that belongs to family Enterobacteriaceae. It is a faecal coliform bacterium commonly found in the lower intestine of warm-blooded organisms. ManyE. colistrains are harmless, and they are a part of the normal microbiota of the gut that keeps the gut healthy. But, some serotypes cause serious food poisoning, severe abdominal cramps, bloody diarrhoea, kidney failure and vomiting. Especially the strainE. coliO157:H7 produces a powerful toxin known as Shiga, which is responsible for severe food poisoning.E. colienter to us through the faecal-oral route. Water, raw vegetables, unpasteurized milk and uncooked meat, are several common sources ofE. coli. Thus, it is possible to minimizeE. coliinfections mainly by proper food preparation and good hygiene.

E. coliis one of the key prokaryotic model organisms used in the fields of biotechnology and microbiology. Hence, in many recombinant DNA experiments,E. coliserves as the host organism. The reasons behind using E. coli as the primary model organism are some characteristics ofE. colisuch as fast growth, availability of cheap culture media to grow, easiness to manipulate, extensive knowledge of its genetics and genomics, etc.

What is Pseudomonas Aeruginosa?

Pseudomonas aeruginosais gram-negative rod-shaped bacterium present in the soil, water and other moist locations. Similar toE. coli,P. aeruginosais an encapsulated bacterium. Moreover, it is a motile bacterium. It possesses a single flagellum. Furthermore,P. aeruginosais a part of the skin flora. It is not a harmful bacterium. But, it acts as an opportunistic pathogen. WhenP. aeruginosais virulent, it causes cancer, cystic fibrosis, and burns.

One of the characteristic features ofP. aeruginosais the fluorescence it produces under UV light. It is due to the production of fluorescent pigment pyoverdin by this bacterium.

What are the Similarities Between E. Coli and Pseudomonas Aeruginosa?

• Both E. coli andPseudomonas aeruginosa是两个bacteria that are gram-negative and rod-shaped.
• They are encapsulated bacteria.
• Moreover, they are opportunistic pathogens in humans.
• Both bacteria are motile.

What is the Difference Between E. Coli and Pseudomonas Aeruginosa?

E.coliis a coliform bacterium that belongs to genusEscherichia. On the other hand,P. aeruginosais a non-coliform bacterium that belongs to the genusPseudomonas. So, this is the key difference betweenE. coliandPseudomonas aeruginosa.

Furthermore,E. coliis a part of normal gut flora whileP. aeruginosais a part of normal skin flora. Besides, a further difference betweenE. coliandPseudomonas aeruginosais thatE. colihas peritrichous flagella whilePseudomonas aeruginosahas a single flagellum.

Summary – E. Coli vs Pseudomonas Aeruginosa

E.coliandP. aeruginosa是两个bacterial species belonging to genusEscherichiaand genusPseudomonas, respectively. Both are grams negative, rod-shaped, encapsulated motile bacteria. Moreover,E. coliis facultative anaerobic, whileP. aeruginosais mainly aerobic. So, this is the key the difference betweenE. coliandPseudomonas aeruginosa. Furthermore,E. colihas peritrichous flagella whileP. aeruginosahas a single polar flagellum.
