“…Considering that, in the area studied, there is frequent activity of horses and capybaras, which are preferred hosts of this ixodid, the possibility of occurrence of A. cajennense in other host species is reduced. This can be correlated with the low mean intensity of ticks associated with the birds found in the present study, which was close to the intensities reported by Ogrzewalska et al (2009) from studying birds in the Atlantic Forest, and Tolesano-Pascoli et al (2010) among birds in the cerrado. Their studies indicated that these birds could be used as alternative hosts for the immature stages of this species.…”

“…Both of these stages are commonly found infesting birds (BARROS-BATTESTI et al, 2006). The absence of adult ticks infesting birds was also mentioned by Labruna et al (2007) and Ogrzewalska et al (2009) after studying birds in Atlantic Forest areas in the state of São Paulo.…”

“…Many bird species have been reported to be their hosts, not only during the larval and nymph stages (BARROS-BATTESTI et al 2006) Few published papers have addressed parasitism of ticks on wild birds. The recent studies by Labruna et al (2007), Ogrzewalska et al (2009Ogrzewalska et al ( , 2010 and Tolesano-Pascoli et al (2010) in Brazil, as well as those carried out by Graham et al (2010) and Jordan et al (2009) can be highlighted. As stated by Ogrzewalska et al (2009), studies on species of ticks carried by wild birds in different ecosystems may help towards understanding their dispersion as possible vectors for disease transmission.…”

Thus, the objective of the present study was to identify the tick species that infested wild birds that are present on the campus of the Federal Rural University of Rio de Janeiro, in the municipality of Seropédica, state of Rio de Janeiro, in remnant fragments of the Atlantic Forest biome, which might provide complementary information for mapping the tick species that infest these animals.…”

“…This association was probably due to the presence (or inclusion among the birds caught) of V. chilensis. It should be highlighted that in most inventories involving parasitism among wild birds, there are reports of greater, and sometimes exclusive, parasitism of the order Passeriformes in areas with typical cerrado vegetation (PASCOAL, 2009;TOLESANO-PASCOLI et al, 2010) and typical areas of Atlantic Forest (LABRUNA et al, 2007;OGRZEWALSKA et al, 2009OGRZEWALSKA et al, , 2010. This order has also been considered to be important for maintaining the lifecycle of ticks such as A. nodosum, playing the role of host for their immature stages (OGRZEWALSKA et al, 2009).…”

The prevalence of parasitic infections, particularly those caused by ectoparasites, may influence the biology and ecology of wild birds. The aim of this study was to investigate occurrences and identify the species of ticks collected from wild birds caught on the campus of the Federal Rural University of Rio de Janeiro. The birds were caught using mist nets between October 2009 and December 2010. In total, 223 birds were caught, represented by 53 species and 19 families in nine orders. Nineteen birds (n = 7 species) were parasitized by immature ticks (prevalence of 8.5%). Forty-four ticks were collected, of which 23 were nymphs and 21 were larvae. There were associations between parasitism by ticks and non-Passeriformes birds, and between parasitism and ground-dwelling birds, which was possibly due to the presence (or inclusion among the captured birds) of Vanellus chilensis (Charadriiformes: Charadriidae). All the nymphs collected were identified as Amblyomma cajennense. In general terms, we must emphasize that wild birds in the study area may play the role of dispersers for the immature stages of A. cajennense, albeit non-preferentially.

The aim of the study was to report tick infestations on wild birds in a region of the eastern Brazilian Amazon and evaluate the rickettsial infection of these ticks. Wild birds captured by mist nets were examined for the presence of ticks, which were collected and identified to species by morphology or molecular methods. In addition, part of these ticks was individually tested by polymerase chain reaction targeting portions of the rickettsial genes gltA and ompA. Among 331 captured birds, representing 56 species, 133 individuals (40.2%) from 34 species were found infested by 443 ticks, being Amblyomma longirostre (Koch) the most common (103 larvae, 12 nymphs), followed by Amblyomma humerale Koch (15 larvae, 3 nymphs), Amblyomma geayi Neumann (seven larvae, one nymph), Amblyomma calcaratum Neumann (one larva, four nymphs), Amblyomma coelebs Neumann (two larvae), and Haemaphysalis juxtakochi Cooley (one larva, two nymphs). Other 285 larvae and 7 nymphs collected from birds could not be identified to species and were morphologically identified as Amblyomma spp. The species A. humerale and A. geayi are recorded for first time parasitizing birds in the Neotropical region. Among 67 A. longirostre and 7 A. geayi, 38 (56.7%) and 4 (57.1%), respectively, were found infected by Rickettsia amblyommii. In spite of R. amblyommii being not currently recognized as human or animal pathogen, there has been serological evidence for human and canine infection by this agent in the USA and in the Brazilian western Amazon.
