Validation and Identification of Invasive Salmonella Serotypes in Sub-Saharan Africa by Multiplex Polymerase Chain Reaction.

Abstract

Salmonella enterica serovar Typhi and nontyphoidal Salmonella (NTS) cause the majority of bloodstream infections in sub-Saharan Africa; however, serotyping is rarely performed. We validated a multiplex polymerase chain reaction (PCR) assay with the White-Kauffmann-Le Minor (WKLM) scheme of serotyping using 110 Salmonella isolates from blood cultures of febrile children in Ghana and applied the method in other Typhoid Fever Surveillance in Africa Program study sites. In Ghana, 47 (43%) S. Typhi, 36 (33%) Salmonella enterica serovar Typhimurium, 14 (13%) Salmonella enterica serovar Dublin, and 13 (12%) Salmonella enterica serovar Enteritidis were identified by both multiplex PCR and the WKLM scheme separately. Using the validated multiplex PCR assay, we identified 42 (66%) S. Typhi, 14 (22%) S. Typhimurium, 2 (3%) S. Dublin, 2 (3%) S. Enteritidis, and 4 (6%) other Salmonella species from the febrile patients in Burkina Faso, Guinea-Bissau, Madagascar, Senegal, and Tanzania. Application of this multiplex PCR assay in sub-Saharan Africa could advance the knowledge of serotype distribution of Salmonella.

John Andrew Crump

Adjunct Professor in the Department of Medicine

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.

Julian T Hertz

Associate Professor of Emergency Medicine

Julian Hertz, MD, MSc, is an Associate Professor of Emergency Medicine & Global Health. He graduated summa cum laude from Princeton University and attended medical school at Duke University, where he received the Dean's Merit Scholarship and the Thomas Jefferson Award for leadership. He completed his residency training in emergency medicine at Vanderbilt University Medical Center and his fellowship in Global Health at Duke.

Dr. Hertz's primary interests include global health, implementation science, and undergraduate and graduate medical education. Dr. Hertz's research focuses on using implementation science methods to improve cardiovascular care both locally and globally. His current projects involve developing interventions to improve acute myocardial infarction care in Tanzania, to improve management of hypertension among Tanzanians with HIV, and to improve post-hospital care among patients with multimorbidity in East Africa.

Dr. Hertz has received numerous awards for clinical, educational, and research excellence, including the Duke Emergency Medicine Faculty Teacher of the Year Award, the Duke Emergency Medicine Faculty Clinician of the Year Award, and the Duke Emergency Medicine Faculty Researcher of the Year Award. He has also received the Golden Apple Teaching Award from the Duke medical student body, the Duke Master Clinician/Teacher Award, and the Global Academic Achievement Award from the Society of Academic Emergency Medicine.
