BERNIER Rachelle

PhD student (Chemistry, biology, parasitology)

I have an initial training in biology, biochemistry, specialising in health biology in tropical environments.

After a Master 2 internship on the characterisation of the gastrointestinal parasite Haemonchus Contortus for its resistance to synthetic anthelmintics and its sensitivity to condensed tannins. I followed up with 2 fixed-term contracts in the continuity of the work carried out during the internship, this time evaluating the efficacy of other secondary metabolites of local plants.

I am now engaged in a PhD thesis on the valorisation of tropical plant species in the fight against ruminant ticks in Guadeloupe : towards the design of a natural acaricide.

Through this thesis project I wish to respond to the therapeutic impasse posed by chemical treatment, particularly that of resistance, with an agroecological solution : phytotherapy.

Research questions :
  • Which local plants can control the infestation of farmed ruminants by Senegalese and Creole ticks, and improve the health and production of Guadeloupean animals? 
  • What are the biological and chemical characteristics of tropical plants with anti-tick acaricide potential, and what use is associated with them?

This work is part of a one health approach. In the long term, the aim is to provide farmers with access to new products and therefore new services in order to ensure the sustainability of the ruminant sector and to guarantee quality meat to consumers.
