Mobility project

Investigating the transmission of Haemonchus contortus between domestic sheep and wild cervids and its potential role in the translocation of anthelmintic resistance mutations between geographical sites

In many parts of the world, livestock and wild mammals share grazing areas, allowing cross-transmission of pathogens, including gastro-intestinal (GI) nematodes. We need to improve our knowledge of the epidemiology of parasitism at the domestic-wildlife interface in order to propose appropriate and sustainable management strategies. Haemonchus contortus is the most common and pathogenic parasitic nematode species of small ruminants worldwide and is a major threat to both domestic livestock and wildlife. This parasite can infect a wide range of ungulates and is an interesting model in which to examine a variety of aspects of livestock-wildlife parasite interactions. Transmission of H. contortus from domestic sheep is potentially a major threat to a number of wildlife species and, conversely, infected wildlife presents a potential mechanism for the translocation of anthelmintic resistant parasites between locations. Southern Alberta is an excellent site in which to address some key questions. Anthelmintic drug resistant H. contortus has emerged as a major pathogen of domestic sheep in this region relatively recently (last 10 years) and sheep pastures are often ranged by wild cervids including white-tailed and mule deer. There are also locations where cervids have no access to sheep pastures providing excellent control populations. Our project aims to use a number of molecular genetic approaches to: (1) investigate the extent of cross-transmission of H. contortus between domestic sheep and wild cervids in southern Alberta, and (2) investigate the role of wild cervids as vectors of anthelmintic resistant H. contortus spread between domestic sheep flocks in southern Alberta.

Biography & research interests

After my veterinary studies, I have decided to continue in research with a master 2 (2004-2005) and a PhD (2005-2008) in ecology. My research during this period focused on the relationships between wild ungulates and their environment, and especially on their time and space use variations in response to resources availability and climatic conditions.
Since 2008, I’m an assistant professor in parasitology at VetAgro Sup – Lyon. I spend half of my time teaching parasitology and supervising vet students. I continue to focus my research on animal behaviour and added additional thematic on host—environment-parasite interactions in wildlife.
