Despite the many studies conducted on the skeletons of birds belonging to the superorder Ratiatae in the subclass Palaeognathae
, such as ostrich or emu, and morphologically large ones, there is no reference to exact measurements of their vertebrae and spinal canal (Sales, 2006; Leite et al, 2012) or they are only insignificant and not very precise mentions (Cobley et al.; Kumar & Singh, 2014).
We describe a new avian HBV causing severe hepatitis in the elegant-crested tinamou (Eudromia elegans), a member of the ancient group of birds the Palaeognathae
, which includes emus (Dromaius novaehollandiae) and ostriches (Struthio spp.).
