“…As examples, we can mention: A. rotundatum on Boa constrictor constrictor in Rio Grande do Norte (PEREIRA et al, 2012); A. dissimile on Eunectes murinus, in Pará (DO NASCIMENTO et al, 2017); and Amblyomma sculptum Berlese, 1888 -published as Amblyomma cajennense (Fabricius, 1787) on Crotalus durissus, in Goiás (SZABÓ et al, 2007). The species A. dissimile and A. rotundatum are the most common ectoparasites of amphibians and reptiles, both distributed in the Neotropics and highly adapted to anthropic environments (DANTAS-TORRES et al 2008GUGLIELMONE et al, 2014;MORAIS et al, 2017;DE ALCANTARA et al, 2018;ODA et al, 2018;SOUZA et al, 2020).…”

The Caatinga rainbow boa (Epicrates assisi Machado, 1945) is a snake belonging to the order Squamata, family Boidae, and subfamily Boinae. It has a wide distribution in Brazil and can be found in the Caatinga biome. The present study aims to report the first occurrence of Amblyomma rotundatum on E. assisi in the municipality of João Pessoa, Paraíba State (PB). On March 3, 2020, a tick collection was performed on the dorsal region of the head of an E. assisi, which was captive at the Arruda Câmara Zoobotanical Park, João Pessoa-PB. After collecting the tick, it was transferred to a flask containing 70º alcohol and sent to the Laboratory of Animal Parasitology of the Federal Rural University of the Semi-Arid (UFERSA) for analysis. Identification was done with the aid of a stereomicroscope using a taxonomic key. The result identified this specimen as a nymph of A. rotundatum. The occurrence of this tick species on E. assisi is reported for the first time and constitutes new data applicable to the ectoparasites that occur in this host species in Brazil.

“…There are 331 amphibian and 550 reptile species in the Brazilian Amazon (Figure 1), although that faunal records are far from complete [2,19]. Brazil has witnessed an increasing number of reports on tick parasitism of amphibians and reptiles over the past few years [20][21][22][23][24]. However, knowledge of this tick fauna as their hosts remains incomplete.…”

“…However, knowledge of this tick fauna as their hosts remains incomplete. To date, major tick-amphibian associations reported in Brazil are the ixodids Amblyomma dissimile, Amblyomma rotundatum, Amblyomma humerale, Amblyomma fuscum and Amblyomma goeldii [20][21][22][23][24], and the argasids Ornithodoros saraivai and Ornithodoros faccinii associated with species Cycloramphus boraceiensis and Thoropa miliaris, respectively [25,26]. Occasional records on reptiles have also been reported for Ornithodoros mimon and Ornithodoros rietcorreai [22].…”

“…The tick A. rotundatum is an obligate parthenogenetic species, although there are six reports of adult males, two males in the laboratory [44] and six in the Amazon region parasitizing Tropidurus sp., Boa constrictor, Iguana iguana, Chelonoidis denticulatus and B. atrox [30,36,[44][45][46][47]. Most publications on A. rotundatum are simple records of its occurrence with some additional data on prevalence and intensity of infestation in the Cerrado, Atlantic forest and Amazon biomes [22,23,31,34,48]. In the Brazilian Amazon, the families Bufonidae (Amphibian) and Boidae (Reptilia) are the most frequently parasitized by A. rotundatum, but there are reports on other species of Amphibian and Reptiles ( Table 1).…”

Ticks are important ectoparasites and can transmit a wide variety of pathogens to animals and humans worldwide. These ectoparasites are the most important vectors of diseases causing pathogens in domestic and wild animals, and the second for man. In Brazil, Spotted Fever is the only disease transmitted to humans by ticks, while for animals we can highlight babesiosis, ehrlichiosis and anaplasmosis. Although ticks are found in all of Brazil’s biomes, little is known about its diversity and host-relations in the Amazon biome. The existing gaps and the lack of research indicate that the diversity of ticks and their possible pathogens are underestimated in the Brazilian Amazon. Therefore, in order to guide the next studies in the Amazon biome, we present in this chapter a compilation of the records of hard ticks and soft ticks parasitizing wild and domestic animals, and humans. We present the general list of ticks for this biome, their distribution, hosts and importance for public health and veterinary. Finally, the ixodofauna found in the Brazilian Amazon and presented here does not match the vertebrate diversity of this biome, which is one of the largest on the planet. Therefore, more acarologists and epidemiologists are needed in this region.

Amphibians and Squamata reptiles belonging to a zoological collection were screened for ectoparasites, which were removed from the hosts and identified using morphological keys. Descriptive statistics and analysis of the association between the parasite and host characteristics (taxonomic group, capture location and habitat) were done. Among the 1256 animals examined (319 amphibians and 937 reptiles), 86 individuals were parasitized, corresponding to a frequency of 6.9% (6.6% reptiles and 7.5% amphibians). Ticks in the adult and nymph stages were identified to the species level; all of them belonged to the species Amblyomma dissimile. The larvae were identified to the genus level and were all Amblyomma sp. In total 69 larvae, 28 nymphs and eight adults were found. The most parasitized species was the frog Rhinella major: 24 parasitized animals of 65 examined (36.9%). There was a difference (P < 0.001) between parasitism by ticks of the genus Amblyomma with regard to the habitat of capture of the parasitized animal, with a higher parasitism rate in hosts that inhabited open areas as compared to animals ensconced in forest areas and edges of forests. New tick-host associations are given.
