The Study of Blood Culture for Prevalent Bacteria and Antibiotic Resistance on Hospitalized Patients

Abstract

Background: Bacteremia means invasion of bacteria to coronary- arthery system. One third of these cases lead to septicemia and in 40-50% cases, it causes patient’s death. Therefore information about resistance and prevalent of bacteria isolated from blood culture is important for deciding about suitable therapeutic management. Methods: This retrospective study was done on all positive blood cultures for typing and detecting of antibiotic resistance during 2001- 2005. Data was analyzed by statistical procedure. Results: In 252 (4.35%) of studied blood cultures, the most prevalent bacteries were Staph. epidermidis (35.2%) and E. Coli (18.5%). The greatest and the least resistance antibiotics were βLactam (75.2%) and glycopeptide (7.8%) groups, respectively. Conclusion: With regard to antibiotic resistance increased during these years, awaring of the last changes about it in every therapeutic center is necessary.
