由于肺炎球菌的自溶，从阳性血培养瓶中恢复肺炎链球菌可能很困难。因此，我们用阳性血培养瓶中的样本评估了Binax now肺炎链球菌抗原检测的性能，并确定了这些瓶中可检测到肺炎链球菌抗原的持续时间。肺炎链球菌抗原试验是从阳性血培养瓶中鉴定肺炎链球菌的另一种方法，即使传代培养阴性，也可以诊断肺炎链球菌菌血症。
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 pnemmococcal 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.
