Emergence of lyme disease in Quebec

Combined impact of habitat fragmentation and climate change on the emergence of Lyme disease in Quebec

Wildlife diseases are generating growing concern on a global scale, for human health as well as for the health of wild and domestic animals. Lyme disease is one of the threat drawing the attention of authorities in Quebec. This disease discovered in the United States in the early 1980s is caused by a bacterium (Borrelia burgdorferi) which is transmitted by a vector, the black-legged tick (Ixodes scapularis). The white-footed mouse (Peromyscus leucopus) is the preferred host of this tick and is also known to be very effective to transmit the bacteria to larval ticks feeding on it. Our project aims to better understand the progression of the Lyme disease vector in Quebec, in time and space, as well as to assess the extent to which climate change and habitat fragmentation promote this expansion.

Restoring contaminated soils

Bio and phytoremédiation

Mining, oil and gas extraction, agriculture and industrial processes can all contaminate soil with discharges of heavy metals and organic products, thus creating a significant problem worldwide. Genome Canada and Genome Quebec fund research on phytoremediation - a promising new biotechnology that uses plants and their associated microorganisms to rehabilitate contaminated sites. Part of the research aim at testing the effectiveness of phytoremediation of willow cultivars and at characterizing bacteria and fungi as well as the biological processes involved in the degradation of pollutants using approaches of genomics and metagenomics. The sequencing of dozens of genomes of microorganisms that are the most effective in detoxifying the soil, will be done. Cleaning services for contaminated soils represent a market of more than $ 30 billion in Canada. Click here for more info.
