Abstract

Nova hantavirus (NVAV) was first identified in a captured European mole (Talpa europaea) in Hungary. Analysis of lung tissues from 94 moles captured in France revealed NVAV in 50% of the animals. Based on the genetic diversity of the cytochrome b mtDNA, moles collected in Poitiers and Bordeaux were more closely related to the Iberian mole (T. occidentalis), a species previously assumed to be restricted to the Iberian Peninsula. Several hypotheses are discussed to explain these observations: 1) the presence of hitherto unnoticed T. occidentalis in southwestern France; 2) the existence of an ancient mitochondrial introgression phenomenon between the two Talpa species, producing a particular phenotype in some hybrids; 3) the existence of a hybrid zone between the two species; and 4) the existence of a new Talpa species. NVAV was not detected in the southwestern moles, which raises the question of the possible presence of a particular Hantavirus species in this population and/or in the Iberian moles.
