A nationwide survey of ixodid ticks was performed in 2011, during which a total of 4237 and 298 ticks were recovered from 1162 dogs and 136 cats, respectively. Haemaphysalis longicornis was the most frequently found tick species on canine hosts (739 dogs), followed by H. flava (166), Ixodes ovatus (139), and Rhipicephalus sanguineus sensu lato (70). H. hystricis, H. japonica, H. megaspinosa, H. formosensis, H. campanulata, H. ias, I. nipponensis, I. persulcatus, and Amblyomma testudinarium were also recovered. H. longicornis was also the most frequently found species on feline hosts (52 cats), followed by I. ovatus (34), A. testudinarium (19), and H. flava (12). H. hystricis, H. japonica, H. megaspinosa, I. nipponensis, I. persulcatus, I. granulatus and R. sanguineus sensu lato were also recovered from cats. The three major species of ticks found on dogs and cats, H. longicornis, H. flava, and I. ovatus, displayed a wide geographical distribution, with specimens found throughout northern and southern Japan. R. sanguineus sensu lato was primarily recovered in Okinawa, but was also found in Kanagawa, Wakayama, Hiroshima, and Yamaguchi Prefectures. A. testudinarium was mainly distributed throughout western Japan, but small numbers were also recovered from Gumma and Shizuoka Prefectures. H. longicornis was more frequently found on dogs in rural areas than those in urban or suburban areas. Exposure to woodland environments was significantly associated with H. flava and I. ovatus in dogs. Dogs in urban or suburban areas encountered R. sanguineus sensu lato more often than other tick species. Most of the cats surveyed in the present study were from rural areas. In the present study, H. hystricis and R. sanguineus sensu lato were found on cats for the first time in Japan.
2011年开展了一项全国性的硬蜱调查，期间分别从1162只狗和136只猫身上采集到4237只和298只蜱。长角血蜱是犬类宿主上最常见的蜱种（739只狗），其次是黄褐血蜱（166只）、卵形硬蜱（139只）和血红扇头蜱（狭义）（70只）。还采集到了猬血蜱、日本血蜱、巨刺血蜱、台湾血蜱、铃头血蜱、伊氏血蜱、日本硬蜱、全沟硬蜱和龟形花蜱。长角血蜱也是猫类宿主上最常见的蜱种（52只猫），其次是卵形硬蜱（34只）、龟形花蜱（19只）和黄褐血蜱（12只）。从猫身上也采集到了猬血蜱、日本血蜱、巨刺血蜱、日本硬蜱、全沟硬蜱、粒形硬蜱和血红扇头蜱（狭义）。在狗和猫身上发现的三种主要蜱种，即长角血蜱、黄褐血蜱和卵形硬蜱，分布广泛，在日本北部和南部均有采集到标本。血红扇头蜱（狭义）主要在冲绳采集到，但在神奈川、和歌山、广岛和山口县也有发现。龟形花蜱主要分布在日本西部，但在群马和静冈县也采集到少量标本。长角血蜱在农村地区的狗身上比在城市或郊区的狗身上更常见。狗接触林地环境与感染黄褐血蜱和卵形硬蜱显著相关。城市或郊区的狗比其他蜱种更常遇到血红扇头蜱（狭义）。本研究中调查的大多数猫来自农村地区。在本研究中，猬血蜱和血红扇头蜱（狭义）在日本首次在猫身上被发现。
