Dual infection with Ehrlichia chaffeensis and a spotted fever group rickettsia: a case report.

Abstract

Well-documented cases of simultaneous human infection with more than one tick-borne pathogen are rare. To our knowledge only two dual infections have been reported: simultaneous human infection with the agent of human granulocytic ehrlichiosis and Borrelia burgdorferi and simultaneous human infection with B. burgdorferi and Babesia microti (1-2). Rocky Mountain spotted fever has long been known to be endemic in North Carolina; cases of human ehrlichial infection were recognized there soon after Ehrlichia chaffeensis was recognized as an important cause of tick-borne disease in the southeastern United States. Because both Rocky Mountain spotted fever and ehrlichiosis are prevalent in North Carolina, occasional cases of simultaneous human infection by rickettsial and ehrlichial agents would not be surprising; however, no such cases seem to have been reported.

During the past 8 years my research interests have changed from a focus on tick-borne disease and endocarditis to a primary focus on healthcare-associated infections (HAIs). Specifically, I have been interested in HAIs in community hospitals. Using prospective data collected as part of our surveillance activities in the Duke Infection Control Outreach Network (DICON), I and my colleagues have focused on these specific areas of research:

• The accuracy and reliability of surveillance definitions used to document and trend rates of HAIs
• Outcomes of HAIs (both financial and clinical) with particular emphasis on bloodstream and surgical site infections
• Trends in HAIs due to pathogens resistant to common antimicrobial agents
• Temporal and geographic variations in the occurrence of pathogens such as methicillin-resistant S. aureus, E coli and Klebsiella pneumonia
• The prevention and control of HAIs with particular emphasis on the potential role of the environment in the transmission of HAIs

As the principal investigator on one of the 5 national epicenter grants funded by the Centers for Disease control I, along with my co-investigators from the Duke and University of North Carolina Division of Infectious Disease, are involved in a 5-year prospective study of the potential benefit of enhanced cleaning methods (such as the use of ultraviolet light emitters) in the prevention of HAIs. This study involves 9 hospitals in North Carolina and Virginia and will include a trial of 4 different cleaning methods utilized sequentially but randomly in these study hospitals over a 28-month time period. Additionally the Duke Epicenter is also undertaking prospective trials investigating the utility and reliability of new (streamlined) definitions of ventilator-associated pneumonia.


Key words that characterize my work: surgical site infections and nosocomial infections.
