Abstract
The efficacy of gelatin for the recovery of Neisseria meningitidis from blood cultures was evaluated in a clinical setting. The organism was isolated from seven patients with meningococcal infections in blood culture media containing 1% gelatin. In contrast, only two blood cultures from these patients were positive in media without gelatin (P less than 0.05). Gelatin did not influence the recovery of other organisms isolated during this study. Conventional blood culture media may be supplemented with gelatin when meningococcemia is suspected.
摘要
在临床环境中评估了明胶对从血培养物中分离脑膜炎奈瑟菌的效果。在含有1%明胶的血培养基中，从7例脑膜炎球菌感染患者中分离出了该菌。相比之下，在不含明胶的培养基中，这些患者只有两份血培养呈阳性（P<0.05）。明胶不影响本研究期间分离出的其他微生物的分离。当怀疑有脑膜炎球菌血症时，传统血培养基可添加明胶。
