Recovery of Streptococcus pneumoniae from positive blood culture bottles may be difficult due to autolysis of pneumococci. Therefore, we evaluated the performance of the Binax NOW S. pneumoniae antigen test with samples from positive blood culture bottles and defined the duration of detectable pneumococcal antigen in these bottles. Use of the S. pneumoniae antigen test is an alternative method for identifying S. pneumoniae from positive blood culture bottles and may enable a diagnosis of pneumococcal bacteremia despite negative subcultures.
由于肺炎链球菌的自溶作用,从阳性血培养瓶中分离出肺炎链球菌可能会很困难。因此,我们用来自阳性血培养瓶的样本评估了Binax NOW肺炎链球菌抗原检测的性能,并确定了这些瓶子中可检测到的肺炎球菌抗原的持续时间。使用肺炎链球菌抗原检测是从阳性血培养瓶中鉴定肺炎链球菌的另一种方法,并且即使在亚培养结果为阴性的情况下也可能有助于诊断肺炎球菌血症。
