“…This finding highlights the necessity of future studies to asses the risk of tick-borne pathogen transmission in this state. Amblyomma fuscum was regarded, until recently, as a rare South American tick whose distribution is restricted to Brazil Barros-Battesti et al 2005). This tick was not listed by Horak et al (2002), in their list of valid tick species of the world.…”

From 2005 to 2009, 147 ticks found on 32 wild animals from or referred to two zoobotanical parks (Parque Zoobotânico Arruda Câmara and Parque Estadual Dois Irmãos) located in northeastern Brazil were identified. Ticks found on two veterinarians working in one of the parks (i.e., Parque Estadual Dois Irmãos), after return from forested areas within the park's territory, were also identified. The following tick-host associations were recorded: Amblyomma fuscum Neumann on Boa constrictor L.; Amblyomma longirostre Koch on Ramphastos vitellinus ariel Vigors and Coendou prehensilis (L.); Amblyomma varium Koch on Bradypus variegates Schinz; Amblyomma rotundatum Koch on Chelonoidis carbonaria (Spix), Chelonoidis denticulata (L.), Micrurus ibiboboca (Merrem), Python molurus bivittatus Kuhl, Iguana iguana (L.) and B. variegatus; Amblyomma nodosum Neumann on Myrmecophaga tridactyla L. and Tamandua tetradactyla (L.); and Rhipicephalus sanguineus (Latreille) on Nasua nasua (L.). The ticks found on the veterinarians were identified as nine Amblyomma larvae. The presence of Am. nodosum in Pernambuco and Am. rotundatum and Am. varium in Paraíba is recorded for the first time and the occurrence of Am. longirostre in Pernambuco is confirmed. Ramphastos vitellinus ariel is a new host record for Am. longirostre whereas M. ibiboboca and B. variegatus are new host records for Am. rotundatum. Finally, the human parasitism by Amblyomma ticks is reported for the first time in Pernambuco, highlighting the potential of tick-borne pathogen transmission in this state.

“…This tick was not listed by Horak et al (2002), in their list of valid tick species of the world. However, this species was recently re-described by Barros-Battesti et al (2005), leaving no doubts about its validity (Guglielmone et al 2009). Adults of Am.…”

“…The basis capituli of is rectangular in shape in A. fuscum (Barros-Battesti et al 2005a), in Bothriocroton oudemansi ) and in A. varium (Onofrio et al 2008), spatulate in the larva of A. longirostre (Barros-Battesti et al 2005b), while flask-shaped in A. geochelone, in A. gervaisi and trapezoidal in A. romitii (Barros-Battesti et al 2007). In male A. geochelone, basis capituli is ornate dorsally with variable brownish and golden yellowish patterns, while it is smooth dorsally with pores and few small sharply pointed spines and two light, straight, diagonal striations are present in male A. gervaisi.…”

The scanning electron microscope (SEM) studies on both male and female tick, Amblyomma gervaisi (Lucas 1847) inhabiting the snake Naja naja were made. Detail of the surface structures as seen under SEM exhibit sexual dimorphism and were compared with other tick species as reported. SEM observations show characteristic alloscutal ornamentation, inornate festoons, triangular licking organ, size of the hypostome, round Haller's organ, genital plate oval in male and slit-like in female, and prominent marginated anal plate. The findings of the present study address the diversity in surface ultrastructure among snake ticks which would help in tick biosystematics.

“…Several different hosts species other than Carnivora are considered the main primary hosts for the adult stage of these tick species in Brazil; i.e. deer are primary hosts for adults of Ixodes aragaoi and Amblyomma triste (Barros-Battesti and Knysak 1999;Szabo et al 2003), capybaras for Amblyomma dubitatum ), reptilia for Amblyomma fuscum (Barros-Battesti et al 2004), tapirs for Amblyomma oblongoguttatum (Labruna et al 2000), horses for Dermacentor nitens, amphibia and snakes for A. rotundatum, porcupines for Amblyomma longirostre, anteater for Amblyomma calcaratum, armadilhos for A. auricularium, and small rodents for I. loricatus nymphs (Guimara˜es et al 2001). The fact that these other animals are the primary hosts for these tick species means that Araga˜o and Fonseca (1961), Barros and Baggio (1992) All records refer to the tick adult stage except when stated.…”

The present study reports field data of ticks infesting wild carnivores captured from July 1998 to September 2004 in Brazil. Additional data were obtained from one tick collection and from previous published data of ticks on carnivores in Brazil. During field work, a total of 3437 ticks were collected from 89 Cerdocyon thous (crab-eating fox), 58 Chrysocyon brachyurus (maned wolf), 30 Puma concolor (puma), 26 Panthera onca (jaguar), 12 Procyon cancrivorus (crab-eating raccoon), 4 Speothos venaticus (bush dog), 6 Pseudalopex vetulus (hoary fox), 6 Nasua nasua (coati), 6 Leopardus pardalis (ocelot), 2 Leopardus tigrinus (oncilla), 1 Leopardus wiedii (margay), 1 Herpailurus yagouaroundi (jaguarundi), 1 Oncifelis colocolo (pampas cat), 1 Eira barbara (tayara), 1 Galictis vittata (grison), 1 Lontra longicaudis (neotropical otter), and 1 Potus flavus (kinkajou). Data obtained from the Acari Collection IBSP included a total of 381 tick specimens collected on 13 C. thous, 8 C. brachyurus, 3 P. concolor, 10 P. onca, 3 P. cancrivorus, 4 N. nasua, 1 L. pardalis, 1 L. wiedii, 4 H. yagouaroundi, 1 Galictis cuja (lesser grison), and 1 L. longicaudis. The only tick-infested carnivore species previously reported in Brazil, for which we do not present any field data are Pseudalopex gymnocercus (pampas fox), Conepatus chinga (Molina's hog-nosed skunk), and Conepatus semistriatus (striped hog-nosed skunk). We report the first tick records in Brazil on two Felidae species (O. colocolo, H. yagouaroundi), two Canidae species (P. vetulus, S. venaticus), one Procyonidae species (P. flavus) and one Mustelidae (E. barbara). Tick infestation remains unreported for 5 of the 26 Carnivora species native in Brazil: Oncifelis geoffroyi (Geoffroy's cat), Atelocynus microtis (short-eared dog), Pteronura brasiliensis (giant otter), Mustela africana (Amazon weasel), and Bassaricyon gabbii (olingo). Our field data comprise 16 tick species represented by the genera Amblyomma (12 species), Ixodes (1 species), Dermacentor (1 species), Rhipicephalus (1 species), and Boophilus (1 species). Additional 5 tick species (3 Amblyomma species and 1 species from each of the genera Ixodes and Ornithodoros) were reported in the literature. The most common ticks on Carnivora hosts were Amblyomma ovale (found on 14 host species), Amblyomma cajennense (10 species), Amblyomma aureolatum (10 species), Amblyomma tigrinum (7 species), Amblyomma parvum (7 species), and Boophilus microplus (7 species).
