Fifty patients(24 female and 26 male)with pressure ulcersassociated with different diseasesand attending AL-yarmouk Teaching Hospital in Baghdad were selected in this study. The duration of sample collection was from March to December 2018. All blood samples collected from patients were submitted to a blood culturing technique to examine bacteremia. The results showed that12 blood bacterial isolates were obtained. The isolated bacteria were subjected to Vitek-2, which is an accurate identification technique. The results of the blood culturing technique revealed that 33.3% were Gram negative bacteria, while 66.6% were Gram positive. Diagnosis by Vitek-2 showed that 33.3% wereStaphylococcus spp. , 33.3% were Enterococcus spp. , 25.1% wereSerratiamarcescens and 8.3% comprised Acinetobacterbaumannii. The results of minimum inhibitory concentration (MIC)by Vitek-2showed that Trimethoprime –Sulfamethazole concentration at 320 µg\ml was the MIC for Acinetobacterbaumanni, while piperacilin, Ticarcillin, and Ticarcillin-Clavulanic acidat 128 µg\ml were the MIC for Serratia marcescens . Acinetobacterbaumanniishowed 100% resistance to all antimicrobial agents, while for the Serratiamarescenceresistancevalues were 54.55%, 54.55%, and 45.45% for isolate numbers 1, 2, and 3, respectively. Gram positive bacteria recorded NitrofurantionMIC of 256 µg\ml against Staphylococcus epidermidisand Enterococcus spp., withboth species showinghigh resistance compared with the others which had a value of87.50%.
