Bacteroides fragilis Isolated from Blood Culture. First Case In Our Hospital

The latest guidelines indicate that both an aerobic and an anaerobic bottle should be present in a blood culture set. In our laboratory, aerobic and anaerobic bottles have been used together for more than 10 years. Here we report a case of Bacteriodes fragilis isolated from blood culture of an 88-year-old patient with colon adenocarcinoma. Although this isolate could not be shown to be the causative agent of true bacteremia, it being the first anaerobic agent isolated from blood culture in our laboratory, we aimed to draw attention to the importance of using anaerobic blood culture bottles in blood culture sets.
