Uncovering the hidden world of parasites inside ticks
When I tell people I study parasites that live inside ticks, I usually get one of two reactions: a shudder of disgust or a puzzled look that says, "Don't ticks already carry enough diseases?"
Disease vectors are living organisms, typically arthropods such as mosquitoes, ticks, fleas, sandflies, and triatomine bugs, that biologically or mechanically transmit pathogenic agents between hosts, thereby enabling the spread of infectious diseases within populations and ecosystems. In vector-borne disease systems, pathogens often undergo essential developmental or replication stages within the vector (biological transmission), or are passively carried on contaminated body parts (mechanical transmission). Research on disease vectors encompasses their ecology, population dynamics, host-feeding behavior, vector competence, insecticide resistance, and interactions with environmental and climatic factors, informing surveillance, risk modeling, and integrated vector management strategies for disease control.

Leishmaniasis is a parasitic disease that affects up to 1 million people worldwide each year. It is caused by the protozoan Leishmania, transmitted through the bite of a sandfly. Once inside its host—human or animal—the parasite ...
