Mycobacterium ulcerans ecovar Liflandii infection in new host in a Cuban crocodile (Crocodylus rhombifer).

Mycobacterium ulcerans ecovar Liflandii has recently been described as the causative agent of fatal disease in different frog species. This is the first report of this pathogen in a Cuban crocodile (Crocodylus rhombifer), which died suddenly in a Hungarian zoo. The authors' findings suggest that M. ulcerans ecovar Liflandii does not exclusively infects anurans and highlights the zoonotic risk posed by this emerging pathogen.
