The contribution of wildlife species to pathogen maintenance in multi-host communities has seldom been quantified. To assess the relative contribution of the main wildlife hosts of animal tuberculosis (TB) to its maintenance, we estimated the basic reproduction number (R0) of Mycobacterium tuberculosis complex in wild boar and red deer at 29 sites...
Article
Non‐tuberculous mycobacteria (NTM) circulate between the environment, animals and humans entailing a double concern: their ability to interfere with tuberculosis diagnosis and their potential to cause infections in their hosts. However, published records on NTM infections in animals are still scarce. The aims of the present study were to describe t...
Article
In recent years, many non-tuberculous mycobacteria (NTM) species have been recognized as pathogens for humans and animals. Molecular diagnostic techniques enable rapid identification and characterization of the different species of mycobacteria. NTM are inhabitants of the soil and water, and enter the body through a defect in the skin or mucosa, ca...
