We study these host-parasite interactions and the impact of associated environmental perturbations, with a multi-faceted approach:<\/p>\n<ol style=\"text-align: left;\">\n<li style=\"text-align: left;\">Molecular\/cellular: with which mechanisms do parasites manipulate the flow and precision of intra-host biological information transfer, thus expanding their phenotypic diversity? What are the implications in terms of pathogenicity?<\/li>\n<li style=\"text-align: left;\">Individual\/populations: the study of communities and associated perturbations \u2013 be they environmental (hydrological cycles, etc.) or anthropogenic (urbanisation, trade, agro-pastoral practices, public health policies) \u2013 provides a integrative vision of transmission and the risks of infection.\n<\/li>\n<\/ol>\n<p style=\"text-align: left;\">Monitoring a system&#8217;s responses to perturbations often provides a better understanding of it. Predicting the consequences of environmental\/anthropogenic changes is also a major societal expectation, both in terms of conservation ecology (epidemics, invasive species), public health (vaccination, treatments, etc.), or veterinary health (replacement of traditional breeds).<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=&#8221;1&#8243;

experimental and mechanistic approaches for molecular and cellular biology; as well as bioinformatics analyses of large observational or experimental datasets.<\/p>\n<p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=&#8221;1&#8243;
