Growing Ticks

Growing Ticks

Ticks are one of the most significant vectors of infectious disease in the world, responsible for transmitting, most famously, Lyme disease, but also anaplasmosis, Powassan virus and more. And it isn’t just humans that suffer. Tick-borne illnesses also affect animals including cattle, which can have significant economic impact on farmers. Scientists are investigating these blood suckers in the hope of developing repellents, disease treatments and vaccines, and to do so they need a steady supply of ticks and, therefore, blood – these days, often provided by synthetic tick-feeding systems. The one pictured shows fully engorged Haemaphysalis longicornis ticks, native to Asia, and consists of a thin silicone membrane mimicking skin above a supply of, in this case, bovine blood. These systems enable the feeding and full reproductive cycle of ticks with the advantage of being cheaper, less variable and more ethical than the alternative method: using live animal hosts.

What is BPoD?

BPoD stands for Biomedical Picture of the Day. Managed by the MRC Laboratory of Medical Sciences until Jul 2023, it is now run independently by a dedicated team of scientists and writers. The website aims to engage everyone, young and old, in the wonders of biology, and its influence on medicine. The ever-growing archive of more than 4000 research images documents over a decade of progress. Explore the collection and see what you discover. Images are kindly provided for inclusion on this website through the generosity of scientists across the globe.
