Researchers at Mayo Clinic have identified a possible cause for a rare infection in heart and lung transplant recipients: the donor.

Bobbi Pritt, M.D., a Mayo Clinic parasitic diseases expert, says, as the last of the winter's snow melts, ticks start coming up from under the grass looking for a "blood meal." She says that this year, after a relatively mild winter, ticks got an early start. This means that tick season could be particularly busy. In this "Mayo Clinic Minute," Dr. Pritt explains an easy trick to remember the best ways to protect yourself from tick bites.

On the April 22 broadcast of Mayo Clinic Radio, co-hosts Tracy McCray and Tom Shives, M.D., spoke with Bobbi Pritt, M.D., Director of the Clinical Parasitology Laboratory, about an update on Lyme disease predictions for 2017.

With tick season underway in parts of the United States, it's important to understand the signs and symptoms of Lyme disease to determine when to seek medical treatment. Bobbi Pritt, M.D., Director of the Clinical Parasitology Laboratory in Mayo Clinic’s Department of Laboratory Medicine and Pathology, identifies Lyme disease signs and symptoms at AccuWeather.com.

Bobbi Pritt, M.D., Director of the Clinical Parasitology Laboratory in Mayo Clinic’s Department of Laboratory Medicine and Pathology, discussed how to safety remove ticks from skin with AccuWeather.com.

On March 21, Bobbi Pritt, M.D., Director of the Clinical Parasitology Laboratory in Mayo Clinic’s Department of Laboratory Medicine and Pathology, presented “Advances in Diagnosing Tickborne Diseases” during a live webcast for the Centers for Disease Control Public Health Grand Rounds session.

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.

The new Gastrointestinal Pathogen Panel, PCR, Feces test is now available to the Mayo Clinic practice and Mayo Medical Laboratories clients.

Infectious diarrhea is a common and usually self-limited illness. While most patients with infectious causes of diarrhea will get better on their own, there are certain scenarios in which testing is indicated. The The FilmArray gastrointestinal panel is a multiplex PCR test delivering rapid and cost-effective testing results. It is capable of detecting DNA or RNA of 22 pathogens in approximately 1 hour from stool submitted to the laboratory.

Helicobacter pylori (H pylori) infection is among the most common bacterial infections worldwide with approximately one-half of the world’s population infected. Several invasive and noninvasive testing methods are available to detect H pylori infection.

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."
