Resumen

CASTILLO-MARTINEZ, Antonio et al. Amblyomma mixtum Koch (Acari: Ixodidae) in peridomestic environments of the Otomi- Tepehua Region, Hidalgo, Mexico. Rev. chil. entomol. [online]. 2020, vol.46, n.4, pp.661-669. ISSN 0034-740X.  http://dx.doi.org/10.35249/rche.46.4.20.12.

In Mexico, 99 tick species have been registered and 26 species of Amblyomma genus are known; the Hidalgo state does not have updated catalogs of Amblyomma spp. Between October 2019 and March 2020, were samples of ticks done in the Otomi-Tepehua Region directly from cattle, horses, dogs, cats, humans, leaf litter, weeds, resting places of animals and animal corpses. In the municipalities of Huehuetla, Tenango de Doria and San Bartolo Tutotepec were gathered 735 samples from warm weather rangelands; 494 of the no engorged ticks were randomly selected and taxonomically recognized as A. mixtum Koch, 1844 (Acari: Ixodidae). The ticks were caught from domestic hosts (n = 177), horses (n = 172), animals resting places (n = 51), humans (n = 34), animal corpses (n = 31) and cattle (n = 29). The locality that yielded the highest number of ectoparasites was Río Blanco (16.5%), followed by San Antonio (12.7%), El Canjoy (11.1%), San Isidro (9.5%) and La Esperanza Uno (8.9%); the highest infestation rates found were in horses (34.8%) and canines (32.9%), with all other host types under 10%. 13 ixodides A. mixtum were identified from humans that presented a clinical profile of fever (≥ 102.2 °F), severe muscle pain, lethargy, headache, papules and scoriations at the point of the tick bite. The tick A. mixtum is present in peridomestic environments of the Otomi Tepehua Region, where animal horses and canines serve as the principal disseminators from the rangelands to the rural housing.
