Jun 25, 2022 · Schema of P. aeruginosa pathogenesis.P. aeruginosa can be traced everywhere including hospital environments and cause serious infection of almost any organ. LPS induces TLR-4-dependent and ...
Aug 8, 2023 · Pseudomonas aeruginosa is a gram-negative, aerobic, non-spore forming rod that is capable of causing a variety of infections in both immunocompetent and immunocompromised hosts.[1] Its predilection to cause infections among immunocompromised hosts, extreme versatility, antibiotic resistance, and a wide range of dynamic defenses makes it an extremely challenging organism to treat in modern-day ...

Oct 10, 2019 · Abstract. Pseudomonas aeruginosa is a Gram-negative opportunistic pathogen and a model bacterium for studying virulence and bacterial social traits. While it can be isolated in low numbers from a wide variety of environments including soil and water, it can readily be found in almost any human/animal-impacted environment.

As with most bacteriological specimens, a Gram stain is performed, which may show Gram-negative rods and/or white blood cells. P. aeruginosa produces colonies with a characteristic "grape-like" or "fresh-tortilla" odor on bacteriological media.
The genus Pseudomonas contains more than 140 species, most of which are saprophytic. More than 25 species are associated with humans. Most pseudomonads known to cause disease in humans are associated with opportunistic infections. These include P aeruginosa, P fluorescens, P putida, P cepacia, P stutzeri, P maltophilia, and P putrefaciens. Only two species, P mallei and P pseudomallei, produce ...

Pseudomonas aeruginosa is a Gram-negative, rod-shaped, motile organism (polar flagella) which characteristically produce water-soluble pigments which diffuse through the medium. The best known are pyocyanin (blue-green), pyoverdine (yellow-green, fluorescent), and pyorubin (red-brown, produced by a small proportion of strains).
