Abstract
During 2011, 1900 clinical specimens (urine, wounds, burns, blood and sputum) and 240 hospital environment specimens were collected from four hospitals in Baghdad/Medical city including: Baghdad Teaching Hospital, The Martyr Gazi Al-Hariry Hospital, Welfare Teaching Hospital and The Burn Specialist Hospital. All specimens were cultured and 128 Acinetobacter baumannii were obtained from clinical and environmental specimens in a ratio of 6.05% (n=115) and 5.42% (n=13), respectively. These isolates were identified using microscopic examination, biochemical tests and Api 20 E system.The slide agglutination technique for rabbit immune sera and A. baumannii bacteria was used and our data analysis revealed a serological relatedness among the isolates. We found 22 different serotypes for 128 clinical and environmental A. baumannii isolates. The most common serotype was serotype 1 which included 34 isolates (26.56%) and there were 40 (31.25%) miscellaneous isolates which isolated from different specimens, departments and hospitals. Notably, they didn’t arrange within any of the 22 serotypes. Upon such findings we may conclude, there is a wide variation in serological characteristics of the locally isolated A. baumannii.
