Abstract Background Nosocomial infections pose significant threats to hospitalized patients especially the immunocompromised ones such as cancer patients. Methods This study examined the microbial spectrum of gram-negative bacteria in various infection sites in patients with leukemia and solid tumors. The antimicrobial resistance patterns of the isolated bacteria were studied. Results The most frequently isolated gram-negative bacteria were Klebsiella pneumonia followed by Escherichia coli . We report the isolation and identification of a number of less-frequent gram negative bacteria Chromobacterium violacum Burkholderia cepacia Kluyvera ascorbata Stenotrophomonas maltophilia Yersinia pseudotuberculosis and Salmonella arizona . Most of the gramnegative isolates from Respiratory Tract Infections RTI Gastro-intestinal Tract Infections GITI Urinary
