Abstract
To investigate the performance of a nucleic acid amplification test (NAAT) for the diagnosis of Mycobacterium tuberculosis bacteremia, 5-ml aliquots of blood were inoculated into bioMérieux mycobacterial (MB) bottles and incubated, and 5-ml aliquots of blood were extracted and tested by real-time PCR. Of 25 samples from patients with M. tuberculosis bacteremia, 9 (36.0%) were positive and 1 (1.5%) of 66 control samples was positive by NAAT. The NAAT shows promise, but modifications should focus on improving sensitivity.

John Andrew Crump
I am an Adjunct Professor of Medicine, Pathology, and Global Health. My work with Duke University is primarily based in northern Tanzania where I am former Site Leader and current Principal Investigator on projects linked to Duke University’s collaborative research program at Kilimanjaro Christian Medical Centre. I oversee the design and implementation of research studies on infectious diseases, particularly febrile illness, invasive bacterial disease, zoonotic infections, and infectious diseases diagnostics. In addition, I am Professor of Medicine, Pathology, and Global Health at the University of Otago and a medical epidemiologist with the US Centers for Disease Control and Prevention (CDC). My CDC work focuses on non-malaria febrile illness.
