Abstract Background : Human parvovirus B19 infection has been known to cause chronic anemia, pure red cell aplasia, glomerulopathy and allograft dysfunction in kidney transplant (KT) recipients. The aim of this study was to evaluate the prevalence and clinical significance of B19 infection in KT recipients. Methods : Five hundred and thirty seven serum samples from 167 KT recipients were included in the present study. The prevalence of B19 infection was based

Abstract Background: The erythromycin (EM) resistance rates and emm genotypes of Streptococcus pyogenes could vary by geographical location and study period. The purpose of this study, involving a large number of children, was to determine EM resistance rate and its resistance mechanism of S. pyogenes, and to compare these results with those of previous studies performed at the same area. Methods: Throat cultures were taken from 2,351 healthy children of four elementary schools from October through December, 2004 in Jinju. A total

Abstract Background: This study compared the growth of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Streptococcus pneumoniae, and Haemophilus influenzae in blood culture bottles containing anticoagulants, sodium polyanethol sulfonate (SPS) and sodium citrate. Methods: One hundred and fifty colony forming units of five different bacterial species were inoculated into standard aerobic (SA) and standard anaerobic (SN) bottles and were combined with 5 mL of human blood in solution with SPS or sodium citrate. Time to detection (TTD) was then monitored using the BacT/ Alert 3D

Abstract Background: Blood culture is essential for the diagnosis and management of bloodstream infections. Blood volume is a key parameter determining the success of blood cultures. Studies comparing compliance between physicians and phlebotomists regarding optimal blood culture procedure are very rare in Korea.  Methods: After educating physicians (interns) and phlebotomists about the correct procedure for blood culturing, the blood volumes of forty-three percent of randomly selected aerobic and anaerobic culture sets for adult patients (≥18 years old) were compared between these two groups over a period of three months. Physicians obtained blood from all admitted patients except those in the

Abstract Background: By varying the collected blood volume and storage temperature of the blood culture bottles prior to entry in an automated blood culture system, growth of organisms will be affected. Methods: Blood culture bottles with a 20 mL blood volume per set were stored at 37oC (1st period) and room temperature (RT, 2nd period) upon arrival at the laboratory after working hours compared to baseline period (10 mL, RT). The time to detection (TTD) for all strains and the number of days until the final report after bottle entry were compared among the three periods. Results: The median TTD for all strains was 13.5 h, 10.6
