Acinetobacter spp. are aerobic, non-fermentative, Gram-negative rod-shaped bacteria. The genus Acinetobacter belongs to the Moraxellaceae family.
In the context of nosocomial infections, the species Acinetobacter baumannii is of particular importance. This pathogen can also form biofilms.
As nosocomial pathogens, Acinetobacter species cause, among others:
Urinary tract infections
Acinetobacter spp. are ubiquitous. In particular, the bacteria are found in the soil and water. They are also found in the skin and mucous membrane flora of humans and animals.
Relevance of pathogen in transmission in endoscopy
Ear, nose, and throat: Low
Relevance for endoscope surveillance
High concern organism
Nosocomial transmission of Acinetobacter spp. occurs through direct or indirect contact such as staff hands and via medical materials. Acinetobacter spp. can also be transmitted through the air or via contaminated food.
In healthcare facilities, Acinetobacter spp. can also be spread and transmitted through water. The water used for final rinsing of endoscopes must therefore be microbiologically controlled.
Resistance to antibiotics
Acinetobacter spp. are resistant to a variety of antibiotics. Increasingly, Acinetobacter spp. are also multidrug-resistant, including to beta-lactams, fluoroquinolones, and aminoglycosides.
