Lyme disease: a study on the speed of transmission by infected ticks
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 – chipmunks may affect tick infection but the risk of transmission is more complex
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-...

Climate and health: anticipating tomorrow's vector-borne diseases in France
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...

Mathieu Picardeau: tackling the trio of water, rats and leptospirosis
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...
