Title

ASSESSMENT OF ANTIBIOTIC RESISTANCE PATTERN IN ACINETOBACTER BAUMANNII CARRYING BLA OXA TYPE GENES ISOLATED FROM HOSPITALIZED PATIENTS

Pages

  54-61

Abstract

 Background & Objective: ACINETOBACTER BAUMANNII is a Gram-negative coccobacillus and one of the most opportunistic pathogens responsible for serious infections in hospitalized patients.Materials and Methods: During a 12 months study, 221 clinical isolates and 22 environmental ACINETOBACTER BAUMANNII isolates were collected. In vitro susceptibility of ACINETOBACTER BAUMANNII isolates to 13 antimicrobial agents: amikacin, cefepime, ceftazidime, ciprofloxacin, meropenem, piperacillin/tazobactam, sulfamethoxazole/ trimethoprim, imipenem, tigecycline, colistin, gentamycin, ceftriaxone, levofloxacin was performed by the disk diffusion method. Also Minimum Inhibitory Concentration (MICs) of imipenem, levofloxacin and cefepime was performed by the E-test according to Clinical and Laboratory Standards Institute (CLSI) criteria. blaOXA-23, blaOXA- 24, blaOXA-58, blaOXA-51 genes were detected by polymerase chain reaction and sequencing.Results: The result of antimicrobial susceptibility test of clinical isolates by the disk diffusion method revealed that all strains of ACINETOBACTER BAUMANNII were resistant to piperacillin/tazobactam. The rates of resistance to the majority of antibiotics tested varied between 69% and 100 %, with the exception of tigecycline and colistin. Of 221 isolates tested 99 (44.8%) were XDR. All strains carried a blaOXA-51 -like gene. blaOXA-23 gene was the most prevalent among blaOXA-types Conclusion: Colistin and tigecycline can be effective drugs for treatment of ACINETOBACTER BAUMANNII infections.Continuous Surveillance for ACINETOBACTER BAUMANNII multidrug-resistant strains is necessary to prevent the further spread of resistant isolates.
