統計2002年1月1日至2003年6月30日本科現有的血液培養系統BacT/Alert的20908瓶（10454套）成人血液培養瓶中，評估厭氧血瓶的價值。若不考慮革蘭氏陽性桿菌與稀有分離菌，則其他總共有1740套（2695瓶）為陽性，其中30.1%套（523瓶/1740套）僅需氧瓶有長，另外僅15.1%套（262瓶/1740套）僅需厭瓶有長，54.8%(955/1740)需氧與厭氧皆長。97.4% (38/39) yeast like、88.5% (23/26) Acinetobacter baumannii、84.6%(22/26) Burkholderia cepacia、68.8% (22/32) Pseudomonas aeruginosa 與96.8% (30/31)micrococcus 僅需氧瓶才長。對於厭氧菌的分離，19.4%(7/36)厭氧菌僅長在需氧瓶，75%(27/36)厭氧菌僅長在厭氧瓶，另外5.6%(2/36)厭氧菌在需氧與厭氧瓶皆能生長。

To evaluate the use of routine anaerobic blood cultures with the BacT/Alert system, results of 20908 blood culture vials processed from 1 January 2002 through 30 June 2003 for adults were reviewed. There were 2695 positive vials from 1740 sets not inclusive of Gram positive bacillus and few isolation strains. 30.1% (523/1740) sets grew only in the aerobic bottles, another 15.1% (262/1740) sets did only in the anaerobic bottles. 54.9% (955/1740) were culture positive in both aerobic and anaerobic bottles. 97.4% (38/39) yeast like, 88.5% (23/26) Acinetobacter baumannii, 84.6% (22/26) Burkholderia cepacia, 68.8% (22/32) Pseudomonas aeruginosa and 96.8% (30/31) micrococcus strains of sets were almost only isolated from aerobic blood vials. For the isolation of anaerobes, 19.4% (7/36) anaerobes grew only in aerobic vials and 75% (27/36) grew positive only in anaerobic bottles and 5.6% (2/36) both vials positive. 30.4% (290/955) anaerobic bottle grew earlier than the aerobic bottle. Among these 290 earlier anaerobic bottles, 10.3% (30/290) earliers were at least one day. My findings suggested that omitting the use of the anaerobic blood culture vial will seriously compromise the recovery of some anaerobes and will delay blood culture reports.
