چکیده مقاله:

Introduction and objectives: Septicemia is one of the main causes of mortality and morbidity especially in neonates and children. Blood culture is the most common and important method for diagnosis of bacterial systemic infections. The mortality rate is reported from 20% to 50% in cases of bacteremia. Emergence of multidrug resistant bacterial strains is a main problem in the management of the disease. The current research was undertaken to study the common bacterial pathogens isolated from blood cultures and to determine their antibiotic susceptibility pattern Materials and Methods: In this cross-sectional study, blood specimens were collected from patients referring to emam hospital in Jiroft, south of Iran. The isolated bacteria were identified using conventional methods. Antibiotic susceptibility testing was performed by modified Kirby-Bauer disk diffusion method. Results: In this study, gram-positive bacteria were isolated from 38.1 % of blood cultures and gram-negative bacteria were recovered from 61.9 % of blood cultures. Streptococcus spp were the most common bacteria isolated from blood cultures. Streptococcus spp were the most common gram-positive bacteria and Escherichia coli were the most common gram-negative bacteria isolated from blood cultures. It was found to be 87.5%-gram positive bacteria were sensitive to Nitrofurantoin. About 61.5% of gram-negative bacteria were sensitive to Gentamicin. Conclusion: Present study showed that both gram positive and gram-negative bacteria were responsible for blood stream infections. Streptococcus spp and Escherichia coli were the most common bacteria isolated from blood cultures.
