    Purpose: Nosocomial infections develop after 48-72 hours of hospitalization. Gram negativebacilli are generally the causative agent. 25% of all nosocomial infections develop in theintensive care units. Therefore, patients in the intensive care units are at high risk. This studyaimed to determine the prevalence of nosocomial infections and causative gram negative bacilliin the Intensive Care Unit (ICU).Materials and Methods: 269 patients who were hospitalized in internal medicine intensivecare unit (IMICU) of Dicle University Faculty of Medicine between june 2010- December 2010were included in this study. Culture samples were taken from all of the patients who developsfever ( ?38.5 C) after the hospitalization to the IMICU. Culture of blood, urine, sputum, centralvenous catheters, open wounds and deep tracheal aspirate were taken. Source and the prevalenceof infection and distribution of the isolated causative pathogens were determined in the patientswith gram negative bacilli reproduction.Results: 158 of the patients were male ( 58.7%) and 111 of the patients were female ( 41.3%).The mean ages of men and female were 58.81±16.91 and 56.44±19.16 years, respectively (p=0.286). culture samples were taken from blood (16%), urine ( 8.6%), central venous cathetertips ( 6.3%), deep tracheal aspirates (10%), sputum (2.2%) and wound stabs (2.2%). Nosocomialinfections were detected in 109 patients ( 40.5%). Pneumonia, urinary tract infections andgastrointestinal system infections were the most frequent infections respectively.Microorganisms were isolated from one sample in 97 patients, while 12 patients had more thanfocus. The most commonly isolated organisms were E.Coli (13.8%) and PseudomonasAeruginosa (7.4%), followed by Acinetobacter Baumannii (6.3%) and StenotrophomonasMaltophilia (3.3%). Conclusion: Nosocomial infections in intensive care units have proved to be a serious problem.Surveillance studies should be performed for the isolated causative pathogens and measuresshould be taken to prevent the development of the ICU infections
