Pseudomonas putida
Pseudomonas putida is a Gram-negative, rod-shaped bacterium of the family Pseudomonadaceae.
Pseudomonas putida causes increased nosocomial infection, including among intensive care patients and in the event of immunodeficiency. The following diseases can be caused by this pathogen:
Wound infections
Pneumonia
Urinary tract infections
Skin infections
Meningitis
Sepsis
Pseudomonas putida is ubiquitously distributed in soil, water, plants, and in animals. The bacterium is a biofilm former.
Relevance of pathogen in transmission in endoscopy
Gastroenterology: Not relevant
Pulmonology: High
Ear, nose, and throat: Not relevant
Urology: Low
Relevance for endoscope surveillance
High concern organism
Transmission route
Transmission occurs via contact infection, via contaminated water, contaminated infusion or transfusion solutions, and possibly aerogenic.
Poor water quality can also cause the spread and transmission of this pathogen in healthcare facilities. Break-offs of Pseudomonas putida biofilms in water pipes can contaminate the water and lead to the spread of the pathogen. Thus, a recontamination of a previously reprocessed endoscope may also occur during final rinsing.
Resistance to antibiotics
Pseudomonas putida shows high rates of resistance up to multi-resistance to beta-lactams, carbapenems, and aminoglycosides, among others.
