“…Immature specimens of Amblyomma nodosum, mostly nymphs, have been described previously on several passerine bird species (LABRUNA et al, 2007;OGRZEWALSKA et al, 2009a;TOLESANO-PASCOLI et al, 2010;LUZ et al, 2012), and these hosts seem to be important for its life cycle. Adult A. nodosum ticks feed almost exclusively on anteaters (Tamandua tetradactyla and Myrmecophaga tridactyla) (ARAGÃO, 1936;JONES et al, 1972;BECHARA et al, 2002) and, as stated previously (LABRUNA et al, 2007), this tick's distribution seems to be associated with that of its adult hosts. Since anteaters are widely distributed in the Cerrado (REIS et al, 2006), A. nodosum is expected to be present throughout this biome.…”

We report tick infestations on birds, in the environment and on domestic animals in a non-forested phytophysiognomy, the savanna-like Cerrado sensu stricto, in a natural reserve on the outskirts of the urban area of Uberlândia, Minas Gerais, Brazil. Overall, 238 birds within 50 species, 15 families and six orders were caught. Passeriformes were the most numerous, with 216 birds (90.75%), among which 22 had ticks (n = 31). Within this order, the prevalence of tick infestation was 10.2%, and the abundance and mean intensity were 0.14 and 1.41, respectively. Only immature ticks of the species Amblyomma nodosum were found on the birds. The tick species found both on animals (Rhipicephalus sanguineus, Rhipicephalus (Boophilus) microplus, Amblyomma cajennense and Dermacentor nitens) and in the environment (Amblyomma dubitatum, Rhipicephalus (B.) microplus and Amblyomma cajennense) were as expected. This difference in tick species between the environment and birds possibly occurred because the sampling of the environment was limited to the ground. This study also highlights the importance of the diverse microenvironments used by ticks and hosts in the same area and the complex ecology of bird-tick relationships. Ecological and epidemiological aspects of the findings are discussed.Keywords: Bird, cerrado, tick, passeriformes, ecology. ResumoNesse trabalho relatam-se infestações de carrapatos em aves, meio ambiente e em animais domésticos em uma fitofisionomia não florestal, o Cerrado stricto sensu, de uma reserva natural na periferia da área urbana de Uberlândia, Minas Gerais, Brasil. Para tal, 238 aves de 50 espécies foram capturadas, pertencentes a 15 famílias e seis ordens. Passeriforme foi a mais numerosa, com 216 indivíduos (90,75%), dos quais 22 estavam parasitados com 31 carrapatos. Nos Passeriformes a prevalência de infestação de carrapatos foi de 10,2%, a abundância e intensidade média foi de 0,14 e 1,41, respectivamente. Apenas carrapatos imaturos da espécie Amblyomma nodosum foram encontrados em aves. As espécies de carrapatos encontradas tanto em animais (Rhipicephalus sanguineus, Rhipicephalus (Boophilus) microplus, Amblyomma cajennense, Dermacentor nitens) como no ambiente (Amblyomma dubitatum, Rhipicephalus (B.) microplus, Amblyomma cajennense) foram aquelas já esperadas. Esta diferença de espécies de carrapatos entre ambiente e de aves possivelmente ocorreu porque a amostragem do ambiente se restringiu ao solo. Esse estudo também destaca a importância dos diversos microambientes usados por carrapatos e hospedeiros em uma mesma área e a complexa ecologia das relações ave-carrapato. Aspectos ecológicos e epidemiológicos dos achados são discutidos.

Ticks (Acari: Ixodidae) are obligatory hematophagous ectoparasites of a variety of vertebrate hosts and play an important role in the transmission and ecology of infectious pathogens causing diseases in humans and animals worldwide. Sixty-eight species of ticks exist in Brazil, and at least 23 are found parasitizing wild birds. This number is increasing with the advent of new studies highlighting the underestimated role of birds in the life cycle of these arthropods. In South America, many of these ticks are involved in epidemiology of the life-threatening spotted fever diseases caused by bacteria from the genus Rickettsia (Rickettsiales: Rickettsiaceae). The aim of this paper is to present up-to-date knowledge about the bird-tick fauna of Brazil and their association with rickettsioses. The available literature concerning ticks on birds and tick-borne diseases related to these ticks in Brazil has been revised. It could be concluded that birds play a primary role in life cycles of various tick species, especially during immature stages (larvae and nymphs). The best known is a bird-tick fauna from the Atlantic Forest and from Brazilian savannah called Cerrado in southern and central Brazil, respectively. On the other hand, the knowledge about bird tick parasitism from other Brazilian biomes such as the Amazon, Caatinga, Pantanal and Pampas regions is very scarce and requires further study. Moreover, no studies about the role of birds as mobile hosts for spreading ticks to new areas exist, nor has their role in the natural life cycle of Rickettsia been thoroughly examined.Keywords: Ticks. Ectoparasites. Rickettsia. Disease. Birds. Brazil. ResumoOs carrapatos (Acari: Ixodoidea) são ectoparasitas obrigatórias de uma variedade de hospedeiros vertebrados e têm um papel importante na ecologia e transmissão de diversos patógenos causadores de doenças em humanos e animais no mundo todo. No Brasil existem 68 espécies de carrapatos e pelo menos 23 espécies são encontradas parasitando aves silvestres. Esse número tem crescido com o advento de novos estudos ressaltando o papel das aves nos ciclos de vida desses artrópodes. Na América do Sul alguns desses carrapatos estão envolvidos na epidemiologia de doenças graves para o ser humano, como a febre maculosa, causada por bactérias do gênero Rickettsia (Rickettsiales: Rickettsiaceae). O alvo desse artigo é apresentar o estado atual de conhecimento sobre a fauna de carrapatos encontrados em aves no Brasil e as associações estabelecidas com as riquetsioses. A literatura disponível sobre carrapatos em aves e ocorrência de riquétsias foi revisada e pôde ser concluído que aves têm um papel importante nos ciclos de vida de várias espécies de carrapatos, sendo especialmente importantes para os estágios imaturos (larvas e ninfas). A maior parte do conhecimento sabrecai na fauna de carrapatos de aves dos biomas Mata Atlântica e Cerrado no sudeste e centro-oeste do Brasil. Já o conhecimento sobre o parasitismo por carrapatos em aves dos outros biomas: Amazônia, Caatinga, Pantanal...

“…Campos Pereira et al (2000) reported that Amblyomma species were abundant in the Pantanal, finding a predominance of nymphs in August and September. Although other species of Amblyomma have been reported associated to yellow armadillos (Botelho et al 1989, Guglielmone & Viñabal 1994, Campos Pereira et al 2000, Bechara et al 2002, Robins et al 2003, our data indicate A. cajennense as the predominant tick of yellow armadillos in Pantanal.…”

-Tick species parasitizing yellow armadillo, Euphractus sexcinctus, were recorded from October 2006 to October 2007 in Pantanal. A total of 89 ticks were collected from 23 yellow armadillos. Most ticks (n = 50) were identified as Amblyomma cajennense (Fabricius) (32 males and 18 females). The only other species found was Amblyomma parvum (Aragão) (three females and two males). The remaining ticks were immatures of Amblyomma (29 nymphs and five larvae). The prevalence of A. cajennense was 55%, the mean intensity was 2.7 ± 0.5 (SE) (n = 17) and the mean abundance was 1.5 ± 0.4 (n = 31).
