Vector-Borne Diseases

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."
