Background and Aim: Septicemia or blood infections (Bloodstream infection) are significant as one of the most important causes of mortality among admitted patients in hospitals. In the lack of appropriate treatment will be accompanied by high mortality. The growth of resistance bacteria to common antibiotics is increasing which cause the medical society face lots of problems. The aim of this study was to determine the prevalence of various bacterial blood infections and antibiotic resistances patterns.

Materials and Methods: This cross-sectional study were performed on 195 patients with positive blood culture over three years in the hospital of the Hamadan. The obtained results were analyzed using the software SPSS-V 19.

Results  and Conclusions: Most pathogens isolated from blood cultures were Coagulase-negative Staphylococci (30.77%), 52 (26.67%) Escherichia coli, 12 (6.66%) Proteus Vulgaris, 18 (9.24%) Acinetobacter spp, 10 (5.13%) Enterobacter spp. 8 (4.09%) Staphylococcus aureus, 10 (5.13%) Pseudomonas aeruginosa, and Citrobacter spp. 2 (1.02%), respectively. According to results, Gram-negative bacteria are the most sensitive to Nitrofurantoin, Norfloxacin and Tetracycline whereas Gram-positive bacteria were sensitive to the Vancomycin and ceftriaxone. In this study most bloodstream infections made up patients in the partition of infectious diseases and children. Bacteria causing blood infections in the studied areas mostly belong to the family of coagulase- negative S. aureus and gram-negative bacilli. According to the determination of antibiotic sensitivity patterns of common bacteria in this region, reporting  to physicians can be considered in an experimental treatment which can prevent the phenomenon of antibiotic resistance and therefore the high cost of treatment for patients, reduce health centers.
