The tick was removed and sent to the S\u00e3o Paulo State Department of Health, where it was identified as a male of the species Dermacentor variabilis (Say, 1821), according to the literature and taxonomic keys. The tick was subjected to a PCR test to search for rickettsiae, but the result was negative. The fact that a human entered Brazilian territory unaware that he was parasitized by a hard tick not belonging to the national tick fauna is significant because of the possibility that an exotic species could be introduced and take hold in this country. Another major risk to public health is that this arthropod could be infected with the bacterium Rickettsia rickettsii, as this ectoparasite is the main vector of Spotted Fever on the East Coast of North America.<\/jats:p>","DOI":"10.1590\/s1984-29612021093","type":"journal-article","created":{"date-parts":[[2022,1,12]],"date-time":"2022-01-12T19:32:26Z","timestamp":1642015946000},"source":"Crossref","is-referenced-by-count":5,"title":["Human parasitism by the exotic tick Dermacentor variabilis (Parasitiformes: Ixodida) in Brazil: report of an imported case"],"prefix":"10.1590","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7325-3362","authenticated-orcid":false,"given":"Thiago Fernandes","family":"Martins","sequence":"first","affiliation":[{"name":"Secretaria de Estado da Sa\u00fade de S\u00e3o Paulo,  Brasil; Universidade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriano","family":"Pinter","sequence":"additional","affiliation":[{"name":"Secretaria de Estado da Sa\u00fade de S\u00e3o Paulo,  Brasil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"530","published-online":{"date-parts":[[2022]]},"reference":[{"issue":"14","key":"ref1","first-page":"355","article-title":"Caso \u00edndice de Amblyomma crassum Robinson, 1926 (Acari: Ixodidae) em sucuri (Reptilia: Ophidia) no Brasil","volume":"6","author":"Amorim M","year":"2013","journal-title":"Rev Uniabeu"},{"issue":"4","key":"ref2","doi-asserted-by":"crossref","first-page":"759","DOI":"10.1590\/S0074-02761936000400004","article-title":"Ixodidas brasileiros e de alguns paizes limitrophes","volume":"31","author":"Arag\u00e3o HB","year":"1936","journal-title":"Mem Inst Oswaldo Cruz"},{"key":"ref3","series-title":"Ticks, a monograph of the Ixodoidea.
