General review of tick species present in Portugal

Abstract

At present, 24 species are known to occur in Portugal: Argas vespertilionis, Ornithodoros maritimus and Ornithodoros erraticus in Argasidae; Ixodes acuminatus, Ixodes bivari, Ixodes canisuga, Ixodes frontalis, Ixodes hexagonus, Ixodes ricinus, Ixodes simplex simplex, Ixodes ventalloi, Ixodes vespertilionis, Dermacentor marginatus, Dermacentor pictus', Haemaphysalis hispanica, Haemaphysalis inermis, Haemaphysalis punctata, Rhipicephalus bursa, Rhipicephalus pusillus, Rhipicephalus sanguineus, Rhipicephalus turanicus, Hyalomma lusitanicum, Hyalomma marginatum marginatum and Boophilus annulatus in Ixodidae. The more relevant diseases transmitted to cattle by ticks, particulary in Ribatejo and Alentejo regions, are the babesiosis due to Babesia bigemina and Babesia bovis, the theileriosis by Theileria annulata and the anaplasmosis due to Anaplasma marginale; the theileriosis by Theileria mutans2 may not be considered significant. The sheep and goats parasitoses transmitted by ticks are of less importance than the cattle diseases. However the babesiosis due to Babesia motasi and Babesia ovis and also theileriosis by Theileria hirci3 are present in some districts of the country.
