The diagnosis of blood-borne infections in immunocompromised patients is a major challenge for the clinical microbiology laboratory. Isolation of bloodborne pathogens in these patients has profound clinical implications, yet is fraught with technical problems, including the presence of unusual and difficult to isolate pathogens. Coupled with this is the problem of false-positive blood culture signals from automated blood culture systems which further delays the definitive diagnosis. Here, we present a case of an 8-year-old boy with Ph +ve acute lymphoblastic leukaemia who has repeated 'false positive' blood cultures and later grew an uncommon organism.

假阳性血培养：需要随访


免疫功能低下患者血源性感染的诊断是临床微生物实验室面临的主要挑战。在这些患者中分离血源性病原体具有深远的临床意义，但充满技术问题，包括存在异常且难以分离的病原体。与此相伴的是来自自动化血培养系统的假阳性血培养信号的问题，这进一步延迟了明确诊断。在这里，我们介绍了一个患有 Ph + ve 急性淋巴细胞白血病的 8 岁男孩的案例，他反复出现“假阳性”血培养，后来生长出一种罕见的微生物。
