“…After the reassessment of the taxonomic status and distribution of A. cajennense in Brazil (Nava et al 2014;Estrada-Peña et al, 2014;Martins et al, 2016) we assume that all records from Brazilian Pantanal are A. sculptum. Moreover, we review our field samples and all ticks are A. sculptum.…”

ABSTRACT. This is a commented list of tick's species collected on various wild and domestic animals, including the reports on scientifi c literature for the studied region. Most of animals were small or medium mammals. Carnivores were the main taxa group examined. Although, the pampas deer (Ozotocerus bezoarticus) and giant anteater (Mymercophaga tridactyla) also has a good representation on study. Among domestic animals, dogs, horses and cattle were examined. Summing up, 18 tick species were listed for the region. Sixteen were hard ticks (Ixodidae) and two soft ticks (Argasidae). Amblyomma sculptum was the most common and abundant hard tick. Ornithodoros rostratus (Argasidae) was very abundant, being the more important Argasidae tick on the study region. The following species were colleted or reported on scientifi c literature: KEYWORDS. Nhecolândia, Argasidae, Ixodidae, Pantanal, Biota-MS P rogram. RESUMO. Estado atual dos carrapatos em relação a seus animais-hospedeiros domésticos e selvagens do Pantanal no Estado do MatoGrosso do Sul, Brasil. Este artigo consiste de uma lista comentada das espécies de carrapatos coletadas em diversas espécies de animais selvagens e domésticos incluindo aquelas espécies já reportadas na região. Os animais capturados são em sua maioria mamíferos de pequeno e médio porte. Os carnívoros foi o grupo com maior número de observações. Entretanto, o veado campeiro (Ozotocerus bezoarticus) e o tamanduá bandeira (Mymercophaga tridactyla) também tiveram um número signifi cativamente de amostras. Dentre os animais domésticos, cães, equinos e bovinos foram examinados. No total foram listadas 18 espécies de carrapatos para a região. Dezesseis delas são carrapatos duros (Ixodidae) e duas, carrapatos moles (Argasidae). Dentre os Ixodidae, Amblyomma sculptum foi a espécie mais encontrada, sendo considerada a mais abundante na região. Ornithodoros rostratus (Argasidae) mostrou-se frequente e abundante, sendo o principal representante da família. Somando as coletas com os resultados de literatura, as seguintes espécies foram catalogadas para a região:

“…The related A. sculptum, used in this work, was recently classified as one of the species of the Amblyomma cajennense complex. This species is widely distributed in central and southern Brazil, Paraguay and northern Argentina, and it is the leading species that humans are frequently exposed to in the study area (Beati et al, 2013; Estrada-Pena et al, 2014; Nava et al, 2014). As ixodid ticks constitute an assorted group of more than 720 species (Barker and Murrell, 2004; Nava et al, 2014), it is common for their parasitism to extend to a wide range of animals including humans.…”

The anaphylaxis response is frequently associated with food allergies, representing a significant public health hazard. Recently, exposure to tick bites and production of specific IgE against α-galactosyl (α-Gal)-containing epitopes has been correlated to red meat allergy. However, this association and the source of terminal, non-reducing α-Gal-containing epitopes have not previously been established in Brazil. Here, we employed the α-1,3-galactosyltransferase knockout mouse (α1,3-GalT-KO) model and bacteriophage Qβ-virus like particles (Qβ-VLPs) displaying Galα1,3Galβ1,4GlcNAc (Galα3LN) epitopes to investigate the presence of α-Gal-containing epitopes in the saliva of Amblyomma sculptum, a species of the Amblyomma cajennense complex, which represents the main tick that infests humans in Brazil. We confirmed that the α-1,3-galactosyltransferase knockout animals produce significant levels of anti-α-Gal antibodies against the Galα1,3Galβ1,4GlcNAc epitopes displayed on Qβ-virus like particles. The injection of A. sculptum saliva or exposure to feeding ticks was also found to induce both IgG and IgE anti-α-Gal antibodies in α-1,3-galactosyltransferase knockout mice, thus indicating the presence of α-Gal-containing epitopes in the tick saliva. The presence of α-Gal-containing epitopes was confirmed by ELISA and immunoblotting following removal of terminal α-Gal epitopes by α-galactosidase treatment. These results suggest for the first known time that bites from the A. sculptum tick may be associated with the unknown etiology of allergic reactions to red meat in Brazil.

“…Tick surveys in Georgia (Hanson and Karstad 1959) and Florida (Greiner et al 1984;Allan et al 2001) Amblyommma mixtum and A. tenellum are reported by these names on feral swine here for the first time, but previously, these two species names were treated as synonyms of A. cajennense until their recent resurrections (Nava et al 2014 a, b). Geographically, both species occur in the U.S.A. only in South Texas, and the range of each also includes much of east-central Mexico, but A. mixtum further occupies southern Mexico, all of Central America, and northeastern coastal South America as far south as Ecuador (Estrada-Peña et al 2014;Rivera-Páez et al 2016), whereas the singular, disjunct, and southern-most record for A. tenellum is from Honduras (Becklund 1959). Within this geographic area, all previous references to A. cajennense on feral swine probably refer to A. mixtum, although some limited confusion with A. tenellum ticks cannot be ruled out entirely.…”

We collected ticks from feral swine, Sus scrofa L., during 1-3 September 2015, in pastures known to be infested by southern cattle ticks, Rhipicephalus (Boophilus) microplus (Canestrini), at the Laguna Atascosa National Wildlife Refuge in Cameron County, Texas, U.S.A. All 81 examined feral swine were infested by ticks, but none was infested by R. microplus. Tick species collected were Amblyomma maculatum Koch, Amblyomma mixtum Koch, Amblyomma tenellum Koch, Dermacentor halli McIntosh, and Dermaentor variabilis (Say). This is the first formal report of A. tenellum infesting feral swine.
