Lyme and Tickborne Diseases Research and Education Institute
About the Institute
The Johns Hopkins Lyme and Tickborne Diseases Research and Education Institute (LTBDI) is led by inaugural director Nicole Baumgarth, PhD, DVM. The Institute resides in the Bloomberg School’s Department of Molecular Microbiology and Immunology (MMI). Baumgarth leads the Institute’s research in four areas: vector/tick biology, epidemiology, microbiology, and host immune defense. The Institute focuses on research training and public outreach centered around the increasing threats of Lyme and other tickborne diseases to public health. In addition to Lyme disease, ticks play a role as carriers and reservoirs in over a dozen lesser-known diseases. Some, like Rocky Mountain spotted fever, are caused by bacteria, while others are caused by parasites or viruses.
Mission
Leading research and education on Lyme and other tickborne diseases to advance public health
Vision
To create a society in which an informed public will be protected from tick bites and the diseases they carry through education and provision of effective prophylaxes; and to ensure healthcare providers have access to improved and new diagnostics and therapies to better help those affected by a tickborne illness.

Find a Tick? Send it to LTBDI!
LTBDI has partnered with Maryland Department of Health to identify ticks sent in by the public. Doug Norris and his team are identifying the type of tick and informing the individuals who submit. If you or anyone you know finds a tick(s) and wish for them to be identified, please follow these instructions:
- Use a piece of transparent tape (used for gif wrapping) to suspend/trap the tick.

Tickborne Diseases Research at Johns Hopkins
Johns Hopkins is home to several entities that focus on tickborne diseases research, diagnosis, and treatment.
In addition to LTBDI at the Bloomberg School of Public Health, the , led by Frank Curriero at the Johns Hopkins Spatial Science for Public Health Center, harnesses the power of geography in tickborne diseases research.
In the Johns Hopkins School of Medicine, the , led by Paul Auwaerter, is dedicated to the clinical research of environmental pathogens which improve the diagnosis and treatment of these infections. In addition, the , led by John Aucott, is pioneering patient-based multidisciplinary research in all manifestations of Lyme disease.
