Our vector-borne disease directors
Bobbi Pritt, M.D., is certified by the American Board of Pathology in clinical and anatomic pathology and microbiology. Her research interests include the evaluation and development of novel laboratory methods to aid in the diagnosis of parasitic and vector-borne diseases. Dr. Pritt works collaboratively with academic and public health partners to provide laboratory diagnostics and education in these areas to a global population. Some of her recent work resulted in the implementation of rapid and highly sensitive molecular tests for malaria, microsporidiosis, Lyme disease, and Borrelia miyamotoi infection. Dr. Pritt also played a key role in discovering and describing two new tick-borne pathogens: Ehrlichia muris eauclairensis and Borrelia mayonii. The latter bacterium causes Lyme disease in the upper Midwestern United States.
Elitza Theel, Ph.D., is certified by the American Board of Medical Microbiology. Her research interests include development and evaluation of novel methods for antibody and antigen detection as diagnostics, specifically for vector-borne and fungal diseases. Dr. Theel also spearheads an international laboratory outreach initiative in Belize. This initiative is focused on increasing the in-country diagnostic testing capacity for vector-borne diseases and enhancing the current quality assurance/quality control practices in clinical laboratories throughout the country.
News and updates
The latest
Tick-borne diseases are increasing across the United States as tick populations and their geographic range continue to expand. This presentation reviews current trends in tick-borne diseases, highlights major tick vectors and associated pathogens, discusses prevention strategies, and explores the laboratory's role in supporting accurate diagnosis and patient care.
In this episode of “Answers From the Lab,” host Bobbi Pritt, M.D., chair of the Department of Laboratory Medicine and Pathology at Mayo Clinic, is joined by William Morice II, M.D., Ph.D., CEO and president of Mayo Clinic Laboratories, to talk about the tick season peak that parts of the United States are experiencing, and how to diagnose and prevent Lyme disease.
In this month's "Hot Topic," Elitza Theel, Ph.D., will be discussing laboratory utilization management, specifically for diagnostic testing for tick-borne diseases.
In this month’s “Hot Topic,” Elitza Theel, Ph.D., talks about Mayo Clinic Laboratories’ serologic and molecular testing for the identification of infection with dengue virus. Dengue virus poses a significant public health threat worldwide. Rapid and accurate identification of the infection enables directed monitoring of patients who may be at increased risk of developing hemorrhagic fever of dengue shock syndrome.
Blacklegged ticks (also known as deer ticks) are turning up more frequently in Minnesota, and so are the diseases they carry. Bobbi Pritt, a parasitologist in the Department of Laboratory Medicine and Pathology at Mayo Clinic in Rochester, Minnesota, weighs in on the issue.
In this “Hot Topic,” Bobbi Pritt, M.D., discusses how Lyme disease is the most common vector-borne illness in the United States and Europe and caused primarily by Borrelia burgdorferi in the United States, while B burgdorferi, B afzelii, and B garinii cause Lyme disease in Europe. We will also discuss using PCR and melting curve analysis to identify a new species of Borrelia.
In this “Hot Topic,” Elitza Theel, Ph.D., discusses how common cases of presumed Lyme disease go unreported each year and discusses scenarios in which testing for Lyme disease is indicated and reviews both recommended and inappropriate testing methodologies. The overall focus is on performance of the CDC endorsed two-tiered serologic testing algorithm and the latest CDC recommendations.
During summer activities, it's bound to happen. But how dangerous is it to accidentally swallow a bug? Bobbi Pritt, M.D., a microbiologist, pathologist, and Director of the Clinical Parasitology Laboratory at Mayo Clinic in Rochester, discusses when swallowing an insect is harmless and which ones can be dangerous in The Wall Street Journal column entitled, "Burning Question."
