Abstract
Over the last decade, Acinetobacter baumannii has emerged as one of the main causes of infections acquired in the hospital setting. Outbreaks associated with this pathogen are caused mainly due to contamination and transmission in hospital territories. However, the natural habitats of A. baumannii of clinical significance still remain unclear. In this study, we highlight the isolation and identification of multidrug-resistant environmental strains of A. baumannii from the soil of Mangaluru city. All the recovered isolates were biofilm formers, and two isolates were multidrug-resistant and showed resistance to fluoroquinolone, aminoglycosides, sulfonamide, tetracycline, and carbapenems. In addition, they exhibited protease activity, and produced phospholipase C and siderophore. To the best of our knowledge, this is the first study to isolate and identify drug-resistant strains of A. baumannii from the soil.
