Lyme disease, also known as Lyme borreliosis, is a tick-borne disease. It is the most widespread vector-borne disease in the entire northern hemisphere. Its incidence continues to rise at global level as a result of demographic and environmental factors, including climate change.

Lyme borreliosis is a disease caused by bacteria of the genus Borrelia that are transmitted by a bite from a tick of the genus Ixodes. Scientists from the Institut Pasteur used mice to study the transmission of bacteria by ticks infected with various European and North American species of Borrelia. They found evidence of rapid bacterial transmission following a bite, with infection occurring...

Lyme disease is caused by bacteria transmitted by the bite of an infected tick of the Ixodes genus. Researchers from the Institut Pasteur have investigated tick infection when Siberian chipmunks are present, as these rodents are thought to be a reservoir for the bacteria. This pet, which was popular in the 1970s, was introduced to some forests where it now thrives, like in Sénart Forest, south-...

The impact of climate change on the emergence of diseases is well established. This is particularly true of diseases transmitted by blood-feeding insects, of which the tiger mosquito is now a well-known vector in mainland France. The Fondation Crédit Mutuel Alliance Fédérale is working alongside the Institut Pasteur to combat these diseases, as part of its commitment to the public interest and to...

The Institut Pasteur and INRAE are strengthening their partnership to tackle infectious and toxic risks and prevent zoonotic diseases. Christophe d'Enfert, Senior Executive Scientific Vice-President at the Institut Pasteur, tells us about the importance of this partnership that focuses on the biology of living systems with the aim of improving animal and human health.

Mathieu Picardeau is Head of the Biology of Spirochetes Unit and the National Reference Center for Leptospirosis at the Institut Pasteur. Mathieu is warm, friendly and well-read, with a passion for contemporary art in his free time – but what really gets him excited is a very specific family of bacteria, some of which are fatal for humans. Despite his many responsibilities, he spends time in the...

As a leading biomedical research center in many fields of health, the Institut Pasteur also has an education center which contributes to the dissemination of scientific and medical knowledge. Some of the Education Center's course offerings are digital, including three MOOCs whose registration period is currently underway, on the topics of medical entomology, epidemiology and...

Sarah Bonnet is a "tickologist" – she specializes in the study of ticks. More broadly, she is a veterinarian entomologist and medical, a professor and scientist with a passion for field work. Her research is focused on the little-known field of ticks and their many species. She is an enthusiastic educator who loves sharing her expertise and plans for future research. The upheavals we are...
