“…According to literature data (Aragão, 1936;Guimarães et al, 2001;Souza et al, 2016) (Canestrini, 1888). According to Labruna et al (2005), previous reports of A. incisum from the Amazonian region require confirmation, as they could be misidentified with Amblyomma scalpturatum Neumann, 1906or Amblyomma latepunctatum Tonelli-Rondelli, 1939; hence, we do not consider valid the report by Aragão (1936) of A. incisum in Acre.…”

Ticks and tick-associated spotted fever group Rickettsia from birds in the Southwestern Brazilian Amazon ¤ Garrapatas y su infección por Rickettsia del grupo de la fiebre manchada en aves del sudoeste de la Amazonía Brasileña Carrapatos e sua infeção por Rickettsia do grupo da febre maculosa em aves do sudoeste da Amazonia BrasileiraAbstract Background: South American birds are known to play a significant role in life cycles of various hard ticks, particularly within Amblyomma genus. However, the tick fauna from the Amazon region has been poorly studied, being limited to very few studies. Objective: To report tick infestations on wild birds captured in a region of the Amazon forest, Acre state, Brazil, and to evaluate rickettsial infection in these ticks. Methods: Wild birds were captured by mist-nets and examined for the presence of ticks, which were all collected and identified to species level by taxonomic keys and/or molecular methods. In addition, part of these ticks was individually tested by PCR targeting portions of three rickettsial genes (gltA, ompA, ompB). Results: Among 1,322 captured birds, ¤ To cite this article: Lima MA, Fernandes MT, Muñoz-Leal S, Guilherme E, Ogrzewalska M, Labruna MB.

Ticks and Rickettsia in Amazon birds 79 individuals (6.0%) were infested by one of the following ticks species: Amblyomma nodosum Neumann, 1899 (72 nymphs), Amblyomma longirostre (Koch, 1844; seven larvae, 13 nymphs), Amblyomma humerale Koch 1844 (four nymphs), Amblyomma geayi Neumann, 1899 (two larvae, two nymphs), and 421 larvae of Amblyomma spp Rickettsia sp strain NOD was detected in 3/26 A. nodosum, and Rickettsia amblyommatis in 5/8 A. longirostre and 1/2 A. geayi ticks tested. Conclusion: This is the first study about ticks parasitizing wild birds in Acre state, adding new host-parasite relationships, new tick species records (A. humerale and A. nodosum) and two rickettsial agents (R amblyommatis and Rickettsia sp strain NOD) for the first time in Acre.

“…In Southern America, Brazilian zoo-animal infection cases have been connected to the following tick species of the Amblyomma and Rhipicephalus genera: A. dubitatum , A. calcaratum , A. aureolatum , A. sculptum or R. sanguineus in Southeastern regions of Brazil [ 21 ]. More Amblyomma species were collected from animals kept in zoos located in Northern and Northwestern Brazil: A. dissimile , A. variatum , A. geayi , A. longirostre , A. goeldii , A. humerale , A. naponense or A. nodosum [ 29 , 30 ]. In Europe, Ixodes ricinus is the most common tick found in zoos and wildlife parks or farms [ 20 , 31 , 32 , 33 , 34 ].…”

Role of Zoo-Housed Animals in the Ecology of Ticks and Tick-Borne Pathogens—A Review

et al. 2021

Ticks are ubiquitous ectoparasites, feeding on representatives of all classes of terrestrial vertebrates and transmitting numerous pathogens of high human and veterinary medical importance. Exotic animals kept in zoological gardens, ranches, wildlife parks or farms may play an important role in the ecology of ticks and tick-borne pathogens (TBPs), as they may serve as hosts for local tick species. Moreover, they can develop diseases of varying severity after being infected by TBPs, and theoretically, can thus serve as reservoirs, thereby further propagating TBPs in local ecosystems. The definite role of these animals in the tick–host-pathogen network remains poorly investigated. This review provides a summary of the information currently available regarding ticks and TBPs in connection to captive local and exotic wildlife, with an emphasis on zoo-housed species.

This study aimed to expand knowledge about tick parasitism on wild birds in western Amazonia and provide additional records of species parasitized by ticks in the state of Acre. Birds were captured with mist nets from September 2016 to February 2017 at the Fazenda Experimental Catuaba, in Senador Guiomard, Acre State, Brazil, identified, and thoroughly inspected. Detected ticks were removed with tweezers, stored in labeled collectors containing 70% alcohol, and identified using a stereomicroscope with incident lighting and taxonomic keys at the Department of Preventive Veterinary Medicine and Animal Health of the School of Veterinary Medicine and Animal Science of the University of São Paulo. In total, 203 wild birds were captured, comprising nine orders and 24 families. Among them, 24 birds (11.82%) belonging to 13 species were parasitized by 44 ticks at different stages: 26 Amblyomma sp. larvae, 10 Amblyomma nodosum nymphs, four Amblyomma longirostre nymphs, and four Amblyomma humerale nymphs. This study reports for the first time nine new species of birds as hosts of ticks of the genus Amblyomma in the state of Acre, namely: Monasa nigrifrons, Hypocnemis subflava, Dendrocincla fuliginosa, Sittasomus griseicapillus, Xiphorhynchus guttatoides, Poecilotriccus latirostris, Hemitriccus flammulatus, Ramphotrigon megacephalum, and Turdus amaurochalinus. This study also records, for the first time, A. nodosum ticks parasitizing R. megacephalum and A. humerale parasitizing Momotus momota, S. griseicapillus, and X. guttatoides.
