Mapping Lyme disease enzootic risk and linking to disease outcomes in the United States

Lyme disease is the most commonly reported vector-borne disease in the US, with approximately 30,000 cases reported annually. Human Lyme disease risk is determined by the density of I. scapularis nymphs infected with Borrelia burgdorferi.

Babesiosis emergence in the United States

Human babesiosis is a rapidly emerging tick-borne zoonosis in the United States caused by the protozoan Babesia microti and transmitted by Ixodes scapularis, the Lyme disease vector. Unlike Lyme disease, babesiosis is a potentially fatal disease and poses a threat to blood transfusion recipients.

Role of host community composition on the prevalence and genetic makeup of tick-borne pathogens

The composition of the vertebrate host community has been proposed to influence both the prevalence and genetic makeup of B. burgdorferi. We are examining this effect by comparing three host communities with contrasting host diversities.

Babesiosa-Lyme disease co-infection

Tick-borne diseases are increasingly becoming an important public health issue as is evidenced by the current national epidemic of Lyme disease and the increasing prevalence of human babesiosis, a more serious malaria-like illness caused by the same tick vector.

Human Borrelia miyamotoi Infection in the United States

Borrelia miyamotoi, a spirochete that is genetically related to the species of borrelia that cause relapsing fever, has been detected in all tick species that are vectors of Lyme disease.

Host Diversity and West Nile Virus Transmission in the United States

Increased host diversity has been proposed to decrease human risk for infection with certain zoonotic diseases.

Everglades Arbovirus Project

This project seeks to determine the diversity and abundance of mosquitoes and arboviruses in the regions in and around Everglades National Park, their relationships with the major plant communities and their potential impact on public health.
