Abstract

Background: Infectious diseases are problematic in all around the world especially in the developing countries and early diagnosis of infections and one etiologic agent has a major role in the treatment of one patients. There are some culturing methods consist of CONVENTIONAL, semiautomatic and automatic. One of automatic methods is BACTEC system worked by fluorescent technology and Co2 production of organisms in CULTURE media.Methods: This study is based on observational-descriptive method with simple convenient sampling. We analyzed 262 samples of body STERILE fluids of patients admitted in pediatric and internal wards of a university (Rasol- Acram) Hospital. They are consisting of 150 blood, 46 synovial, 32 CSF, 24 pleural, and 10 peritoneal samples.Results: There were no differences between two sexes in BACTEC and CONVENTIONAL methods. Average age of patients with positive and negative CULTURE in two methods had not differences. 72 (27.5%) samples were positive that 32 (12.2%) samples only in BACTEC method, 4 (1.5%) in CONVENTIONAL method and 36 (13.7%) in two methods had statistical differences (p=0.003). That means positive CULTUREs are seeing in BACTEC more than CONVENTIONAL method. Comparison of two methods in positive blood CULTURE samples had statistical differences (p=0.02) but no statistical differences in other BODY FLUIDS were seen. i. e. positive CULTUREs were seen in BACTEC more than CONVENTIONAL method.Positive CULTURE in these two methods had statistical differences in antibiotic utilization (p<0.001). Positive CULTURE in antibiotic utility was seen in BACTEC more than CONVENTIONAL method. The average time of CULTURE to become positive was 17.5+ 5.88 hours in BACTEC against 62.36+ 13.98 hours in CONVENTIONAL method. Contamination was seeing in 4 samples in BACTEC and 2 in CONVENTIONAL method that had no significant differences.Conclusion: According to these data organism detection in BACTEC CULTURE media from body STERILE fluids overall and specially from blood is more successful than CONVENTIONAL method. It is a better method in antibiotic utilization. BACTEC can isolate organism in shorter duration than CONVENTIONAL method. BACTEC can facilitate early and accurate diagnosis of infectious etiology, shorten duration of hospital stay and decrease mortality and morbidity and cost.
