Extreme Antibiotic Resistant Acinetobacter baumannii-Related Pneumonia in a Regional Hospital

1. Background Hospital-acquired infection is an additional problem for the patient who has been admitted to a clinical setting for some serious illness. This infection is caused by pathogens like Acinetobacter baumannii (AB) which are prevalent in hospital environment (1). A. baumannii has emerged as an important pathogen which has received a great interest during the last two decades (2, 3). These bacteria are etiologic agent of various infections, particularly pneumonia; therefore, they represent an emergent public health problem. Furthermore, such infections are challenging to treat because of extensive antimicrobial drug resistance (4-6). The purpose of this study was to report our experience with five cases of A. baumannii- related pneumonia infections, seen in a regional hospital in Karaj, Iran. The bacterium was isolated and identified based on standard procedures. Similarly, all the isolates were tested for their antibiotic susceptibility based on Clinical and Laboratory Standards Institute (CLSI) guideline (7).
