Description
Summary:In 2018, more than 10 million people visited natural parks and reserves (http://www.brasil.gov.br/noticias/turismo/2018/12/parques-nacionais-batem-recorde-de-visitantes-em-2018), thus identifying areas where human-aggressive ticks occur in nature is a fundamental task in order to prevent tick bites. Some Ornithodoros species are implied in the transmission of relapsing fever Borrelia to humans [2]. [...]inoculation of salivary components after the bite of one of these ticks can trigger toxicosis, that is to say, hypersensitivity and immunological responses ranging from mild dermal lesions to systemic disease [3]. [...]this is the first report of human parasitism by O. rietcorreai in Maranhão state that highlights the role of this tick as an emerging agent of toxicosis, and expands its the distribution towards pre-Amazonian ecosystems.Acknowledgments Fieldwork and collection of ticks was funded by CNPq and FAPEMA (grant #Edital 09/2016 DCR).
