A questionnaire survey for which there were 538 respondents from American clinical microbiology laboratories was used to assess the need for prolonged incubation of Septi-Chek blood culture bottles for the recovery of HACEK bacilli, Brucella species, Francisella tularensis, and nutritionally deficient streptococci from blood. Among a total of 219 reported isolates of these bacteria, in only 6 cases (2.7%) was incubation longer than 7 days required. Only 2 of 136 patients (1.5%) were noted to be bacteremic exclusively following incubation of Septi-Chek blood culture bottles for periods of greater than 7 days. It appeared from the results of this study, that incubation of Septi-Chek blood culture bottles for 7 days is usually sufficient in patients suspected of having bacteremia due to fastidious bacteria.
一项问卷调查收集了来自美国临床微生物实验室的538份反馈，旨在评估延长Septi-Chek血培养瓶孵育时间对从血液中分离嗜二氧化碳噬纤维菌属-心杆菌属-埃肯菌属-金氏杆菌属（HACEK）杆菌、布鲁氏菌属、土拉弗朗西斯菌和营养缺陷型链球菌的必要性。在总共报告的219株这些细菌的分离株中，只有6例（2.7%）需要孵育超过7天。在136例患者中，只有2例（1.5%）是在Septi-Chek血培养瓶孵育超过7天后才被检测出血液细菌感染。从这项研究结果来看，对于疑似因苛养菌导致菌血症的患者，将Septi-Chek血培养瓶孵育7天通常就足够了。
