  • Introduction: Acinetobacter baumannii is one of the gram-negative and non-fermenting bacteria that cause opportunistic infections, especially in hospitals. Due to the emergence of resistance of this bacterium to all types of antibiotics, the periodic study of the resistance pattern is of particular importance. The aim of this study is to determine the frequency of the ESBL gene (SHV) in Acinetobacter baumannii over a period of 6 months.
  • Methods: This study was carried out on 105 isolates of Acinetobacter baumannii collected from different departments of a general hospital over a period of 6 months. The frequency of the SHV gene was tested by PCR.
  • Results: Of a total of 105 isolates, 77 (73.33%) were reported as SHV gene resistant.
  • Conclusion: The spread of ESBL isolates is increasing and represents a major challenge for the treatment of many diseases in the future. Considering that microbial resistance is increasing in the world and especially in Iran, studying the resistance pattern of hospital bacteria is of great importance..
