A case of autochthonous canine leishmaniasis in the Netherlands

The transmission of visceral leishmaniasis (VL) in the absence of its natural vector, the sandfly, is considered exceptional. This report describes VL in a 12-month-old dog which had never been in an area in which VL is endemic but was born in the Netherlands from a bitch that had been infected in Spain. Although the mode of transmission, via the placenta or otherwise, is unknown, it can be concluded that bitches with VL can be a source of infection for their pups, even in a sandfly-free non-endemic area. The dog was successfully treated with allopurinol.
