Keywords: A. baumannii, Multidrug-resistance and Resistotyping patterns


Acinetobacter baumannii regard one of the most important nosocomial bacterium that may infect hospitalized patients especially in ICU, and can cause severe infections

The sensitivity pattern of A. baumannii revealed that the organism was highly sensitive to Colistin (93%), followed by Tigecycline (82 %). A high resistance rate (100%) was reported for Ceftriaxone, Cefixime, Ceftazidime, and Cefoxitin, while for Cefuroxime (92%) and for both Cefepime and Cefotaxime (98 %), also low sensitivity rate was shown by both Imipenem and Meropenem antibiotics against this bacteria with a sensitivity rate (17%), and due to resistotyping, a total of 9 different resistotype patterns were obtained; the most common resistotype was number (3) which include the following antibiotics : (PRL/TAZ,  CAZ, CFP, AZT, MEM, IMP, AK, CN, NET, CIP, AMC, SXT, CRO, CFUR, LEV).

Finally, this study demonstrated the significance of Acinetobacter baumannii as a nosocomial bacterium that may infect hospitalized patients and cause severe illnesses, such as pneumonia, wound infections, bloodstream infections, meningitis, and urinary tract infections
