Nature conservation in the Republic of Korea (ROK), in addition the effects of global warming has increasingly changed Korea’s weather to a subtropical climate has resulted in increased populations of wild animals in association with their ectoparasites. Increased numbers of animal and bird hosts and warmer climate has resulted in higher populations of members of the Family Ixodidae (hard ticks), in addition to habitat and geographical distributions resulting from reforestation. There are; 6 Genera (Amblyomma, Boophilus, Dermacentor, Haemaphysalis, Ixodes, Rhipcephalus) in the Family Ixodidae, and with 35 species. Studies in the ROK over the past 10 years has resulted in the recognition of 3 Genera of Ixodidae (Haemaphysalis, Ixodes, Amblyomma) and 14 species (H. longicornis, H. flava, H. japonica, H. phasiana, H. ornithophila, H. formosensis, Ixodes nipponensis, I. persulcatus, I. turdus, I. pomerantzevi, I. granulatus, I. vespertilionis, I. simplex, Amblyomma testudinarium). A number of tick-borne pathogens, including severe fever with thrombocytopenia (SFTS) virus, tick-borne encephalitis (TBE) virus, Borrelia, Anaplasma, Ehrlichia, Rickettsia, Bartonella, Theileria and Babesia species, have been detected in ticks collected from the ROK. In addition to detecting these pathogens in zoonotic hosts, they have also been detected from pets, domestic animals, and humans. These pathogens often demonstrate vector and host-specificity, while affecting veterinary and medical health. The analysis of vector and pathogen distributions is crucial for the development of diseased mitigation strategies, requiring additional studies to determine the distributions of animal and bird hosts and vectors and associated pathogens.
