Pseudomonas infection

Pseudomonas is a genus of gamma proteobacteria, belonging to the larger family of pseudomonads.

Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas.

P. aeruginosa is an opportunistic human pathogen, most commonly affecting immunocompromised patients, such as those with cystic fibrosis or AIDS. Infection can affect many different parts of the body, but infections typically target the respiratory tract (e.g. patients with CF or those on mechanical ventilation), causing bacterial pneumonia. Treatment of such infections can be difficult due to multiple antibiotic resistance.

P. oryzihabitans can also be a human pathogen, although infections are rare. It can cause peritonitis, endophthalmitis, septicemia and bacteremia. Similar symptoms although also very rare can be seen by infections of P. luteola.

P. plecoglossicida is a fish pathogenic species, causing hemorrhagic ascites in the ayu (Plecoglossus altivelis). P. anguilliseptica is also a fish pathogen.

Due to their hemolytic activity, even non-pathogenic species of Pseudomonas can occasionally become a problem in clinical settings, where they have been known to infect blood transfusions.
