Introduction: Acinetobacters are non fermentative gram- negative bacteria involving in various nosocomial infections. These organisms as opportunistic pathogens are resistant to many antibiotics and cause various infections such as bacteremia, meningitis, pneumonia, urinary tract infections and surgical wound infections.
Materials & Methods: During this study, 66 isolates of Acintobacter baumannii and 46 isolates of non- Acinetobacter baumannii were studied. After species were defined by chemical tests, antibiotic susceptibility of the isolates were tested by standard disk diffusion method.
Results: The findings showed that all the Acinetobacter baumannii strains were resistant to Cefoprazone, Ceftizoxime, Ceftazidime, Ticarcillin/ Clavulanic acid, Cephotaxime, Aztreonam, Meropenem, Cefixime, Ceftriaxone, Carbenicillin, Cephotaxime and Ticarcillin and sensitive to Colistin.
Conclusion: It is concluded that clinical Acinetobacter isolates in general and Acinetobacter baumannii in particular enjoy high degrees of resistance to most the antibiotics, for example the third- generation cephalosporins and broad- spectrum penicillins.
