Deciphering the role of host species for two <i>Mycobacterium bovis</i> genotypes from the European 3 clonal complex circulation within a cattle‐badger‐wild boar multihost system

Bovine tuberculosis is a common disease affecting cattle and wildlife worldwide. Mycobacterium bovis circulation in decreases the efficacy of surveillance control programs cattle. Strains European 3 clonal complex are most frequent France. The aim our work was hence to investigate role played by species two M. strains circulation. WGS collected between 2010 2017 distinct areas (Nouvelle-Aquitaine region, NAq, Côte-d'Or département, CdO), from badgers, wild boars, were used an evolutionary model infer transition three species. We computed host persistence consecutive nodes average number transitions per tree. In total, 144 218 samples respectively CdO NAq. CdO, between-species rates stood out: badgers boars NAq additional fourth rate identified: However, remained rare event. Our results suggest that could be intermediary studied also highlight differences these areas, suggesting pattern does not only depend on other ecological, landscape anthropic factors important.
