First report of adult Hyalomma marginatum rufipes (vector of Crimean-Congo haemorrhagic fever virus) on cattle under a continental climate in Hungary

BACKGROUND: South Hungary is being monitored for the northward spreading of thermophilic ixodid species, therefore ticks were collected from cattle and wild ruminants (red, fallow and roe deer) in the autumn of 2011. FINDINGS: Besides indigenous species (1185 Dermacentor reticulatus and 976 Ixodes ricinus), two Hyalomma marginatum rufipes males were found on two cows, in September eight days apart. CONCLUSIONS: This is the northernmost autochthonous infestation of the type host (cattle) with H. m. rufipes, vector of Crimean-Congo haemorrhagic fever virus. The present findings are suggestive of the moulting success of this Afro-Mediterranean tick species in a continental climate in Central Europe.
