What is Pseudomonas Bacteria?

Pseudomonas is a straight or slightly curved Gram-negative bacterium. It is a nucleus-free bacterium. It moves with extremely flagella and does not form spores. Some strains produce fluorescent pigments or (and) water-soluble pigments such as red, blue, yellow, and green ^[1] . Both oxidase and catalase were positive (except for a few strains) ^[1] . Blue-green or fluorescent-colored colonies with a gingery smell. ^[2]

Pseudomonas is aerobic Gram-negative microbacilli. The fungus is rod-shaped or slightly curved, with a single

Pseudomonas is a non-fermenting bacterium, does not ferment sugars, has no special nutritional requirements, and can grow on ordinary media. The optimum growth temperature is 35 ° C. A few species can grow at 4 ° C or 42 ° C. ^[1]

It is mainly distributed in water, soil, and air. It has a high detection rate in clinical specimens such as wound wound secretions, pus, and blood. It is a common condition-causing pathogen in hospital infections. ^[1]

There are many species of Pseudomonas, containing more than 200 species. ^[1]

P. aeruginosa ^[9] , P. fluorescens ^[9], and P. Pseudomallei ^[9] , Pseudomonas putida ^[1] and Pseudomonas alkaloids ^[1] .

Pseudomonas aeruginosa is a conditional pathogen that can cause disease under certain conditions and is one of the main pathogens that cause nosocomial infections. The bacteria can naturally resist a variety of antibiotics; it has a strong ability to form biofilms and can form biofilms on wounds or medical implants. In the course of treatment, resistance is easy to appear. ^[3]

Pseudomonas fluorescens is a conditional pathogen. It can cause bacteremia, urinary tract infections and other diseases. This bacterium is sensitive to kanamycin and polymyxin. Resistant to common antimicrobials. ^[6]

Pseudomonas putida can cause respiratory and urinary tract infections and wound infections, as well as septic arthritis and bacteremia, and often contaminates blood bank products. ^[6]
