Cercopithifilaria species are tick-transmitted filarial parasites of mammals. In Europe, three Cercopithifilaria spp. are known to parasitize dogs, all occurring mainly in the Mediterranean countries. In Romania, Cercopithifilaria bainae has been reported in a single dog in eastern Romania but the occurrence in other parts of the country is not known. To further elucidate the geographic distribution of Cercopithifilaria spp. infection, 544 ticks were collected from dogs in several locations across Romania. The presence of Cercopithifilaria spp. was investigated with real-time PCR. A single Dermacentor reticulatus female tick was found to be infected with Cercopithifilaria bainae. The finding in the present study is geographically separated from the previous finding in Romania by 800 km, as well as by the Carpathian mountain range. Hence, C. bainae is more geographically widespread in Romania than previously recognized. However, the single detection does suggest that infection is rather uncommon in Romanian dogs. Nevertheless, further studies on Cercopithifilaria spp. distribution and prevalence are needed.
