Title

Frequency of The Bloodstream Infection in Central Hospital of Arak University of Medical Sciences

English Abstract

Background & Objectives: Bacteremia means existence of live bacteria in the bloodstream. Isolation of bacteria from blood can lead to death, hence epidemiologically is important. Therefore the purpose of this study is to determine the frequency of bacteria isolated from blood cultures at Arak university hospital center. Methods: This cross sectional study has been done in period of one year study. Of 4420 blood culture specimen obtained from 2125 patients, 445 specimens were found to be positive in term of bacteremia. These specimens belonging to 229 patients that their blood culture sampling were positive once for 124 persons, twice for 96 persons and three times for 9 persons. Results: A total of 229 strain isolated from clinical specimens include Staphylococcus epidermidis 114(47.5%), Escherichia coli 38 (16.72), Staphylococcus aureus 20 (9.12%), Klebsiella pneumonia 10(4.17%), Brucella species 7(2.92%), Pseudomonas aerogenosa 10(4.17%), Alcaligenes faecalis 10 (4.17%), Enterococcus 9(3.75%), Acinetobacter 4(1.67%), Staphylococcus saprophyticus 3(1.25%), Proteus mirabilis 2(0.84%), Proteus vulgaris 1(0.417%) and Salmonella typhi 1(0.417%). Conclusion: In Conclusion, the most isolated organisms among septicemic cases were belonging to the gram-positive class. This finding is in agreement with most of the international studies. Nevertheless the burdens of highly pathogen gram negative bacteria like E.coli, Brucella and Acinetobacter can cause complications should be taken seriously. In addition sample collection procedure needs to be revised.
