Acinetobacter junii is rarely a cause of disease in humans. A. junii has mainly been associated with bacteremia in preterm infants and pediatric oncologic patients.
Acinetobacter junii is one of more than 50 different species belonging to the genus Acinetobacter, most of which are nonpathogenic environmental organisms. They may cause opportunistic infections only in people with compromised immune status or with an indwelling device (such as urinary catheters, vascular access devices, endotracheal tubes, tracheostomies, enteral feeding tubes and wound drains), or both.
Acinetobacter species are ubiquitous and can be isolated from many sources including soil, water, sewage, and food. Acinetobacter species can colonize skin, wounds, the oral mucosa, and respiratory and gastrointestinal tracts.
Elevated levels of A. junii were found in patients with Crohn’s disease.
Patients with chronic IBS-diarrhea that respond favorably to a short-term low FODMAP diet tend to have higher levels of A. junii compared to non-responders.
