RESUMO
BACKGROUND: Analysis of the species and antimicrobial susceptibility trend of bacterial and fungal isolate from blood can provide the clinicians with important informations for the treatment of the patients. METHODS: We analyzed the species and antimicrobial susceptibility trends of microorganisms isolated from blood cultures from 1986 to 1996 at Kyunghee Medical Center. Identification of organism was based on conventional methods or commercial kit systems. Antimicrobial susceptibility test was done by the NCCLS disk diffusion method. RESULTS: The positive blood culture was obtained from 3,559 patients. Among the patients 95.6% showed aerobic and facultative anaerobic bacteria, 0.9% anaerobes, and 3.6% fungi. Escherichia coli was isolated most frequently, followed by Coagulase-negative staphylococcus, Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Enterococcus, alpha- hemolytic Streptococcus and Serratia. The proportion of patients with E. coli decreased from 34.5% in 1986 to 22.1% in 1996, while that of S. aureus increased from 9.7% to 13.9%. Proportion of methicillin-resistant S. aureus and the third generation cephalosporin-resistant K. pneumoniae increased during the study period. CONCLUSIONS: We conclude that E. coli is the most common cause of bacteremia at Kyunghee Medical Center. The third generation cephalosporin-resistant K. pneumoniae and methicillin- resistant S. aureus are increasing in proportion.

We experienced two AB3 and a B3 from a 27-year-old student and his family. B3 subgroup was confirmed by delayed and weak mixed-field agglutination with anti-B serum, adsorption-elution test, serum and saliva hemagglutination inhibition test and family study. We report a family case of AB3 and B3 with brief review of literatures.
