Abstract
Blood culture is one of the most important clinical examinations for infectious diseases. In this report, we review our blood culture test in recent a couple of years. From April 2014 to June 2016, 4482 blood culture test were ordered in National Center for Geriatrics and Gerontology in Obu, Japan. In these cases, 611 teste were positive result (positive rate 13.6 %). The percentage for obtaining multiple blood culture sets was 76.6 % during study period. There were 217 male and 144 female with age 80.4 years old. The cultured bacteria were Escherichia coli 68 cases (17.75 %), S.aureus 32 (8.36), S. epidermidis (MRS) 28 (7.31 %), Klebsiella pneumoniae 24 (6.27), Escherichia coli (ESBL) 22 (5.74), S.aureus (MRSA) 16 (4.18 %), β-Streptococcus (group-G) 11 (2.87 %), Enterococcus faecalis 9 (2.35 %), Serratia marcescens 8 (2.09), Corynebacterium spp. 8 (2.09), St.pneumoniae 6 (1.57), St.agalactiae (B) 6 (1.57 %), S.epidermidis 6 (1.57 %), S. homins (MRS) 6 (1.57 %), Prop.acnes 6 (1.57 %), E.aerogenes 6 (1.57 %), Proteus mirabilis 5 (1.31 %), Enterococcus faecium 5 (1.31 %), E.cloacae 5 (1.31 %), Bacillus spp. 5 (1.31 %), St.bovis 4 (1.04 %), S. parasanguinis 4 (1.04 %), S. hominis 4 (1.04 %), Corynebacterium striatum 4 (1.04 %), Bacillus cereus 4 (1.04 %), A.baumannii 4 (1.04 %) and others 77 (20.1 %), respectively. In our institute, reasonable blood culture test was performed as acute care hospital. However we try to obtain more multiple blood culture sets.
