White-tailed deer, Odocoileus virginianus, are significant reservoir hosts of Borrelia burgdorferi, the causative agent of Lyme disease. Hard ticks serve as vectors of both B. burgdorferi and Borrelia lonestari, a species reported from the southeastern United States and associated with Southern Tick Associated Rash Illness or STARI. Winter ticks, Dermacentor albipictus, were collected from hunter-killed deer in Cheatham County, Tennessee in October and November of 2005. Six of 18 (33%) pooled tick samples tested positive for Borrelia species; two of six were identified as B. burgdorferi and four as B. lonestari. This investigation demonstrates that both B. burgdorferi and B. lonestari are present in O. virginianus populations in Cheatham County, Tennessee. It is noteworthy that D. albipictus is capable of harboring Borreliae from infected white-tailed deer. This is the first report of Borrelia detection in D. albipictus in Tennessee.

Work process redesign is an effective tool to assist laboratories in identifying areas for improvement. This article presents the experiences and results of Vanderbilt University Medical Center's Transfusion Service in undergoing a work process redesign project to reduce costs and increase growth potential. Opportunities for improvement were identified, and processes were redesigned to enhance efficiencies and increase workload capacity. Areas where opportunities for improvement were identified included work-flow, work process, personnel usage, task delegation, information transfer, physical layout, and communication. The thorough review and redesign of the work processes resulted in a greater demonstrated workload capacity of 381% for pretransfusion testing (antibody screens ABO/D typing, and immediate-spin crossmatches), using no additional FTEs.
