“…In the present study, adults of A. geayi and adults and nymphs of A. varium were identified on B. tridactylus, corroborating the studies of SERRA-FREIRE et al (1993) andMARQUES et al (2002), who also identified adults of these same species of ticks in this same host in the North region of Brazil. Additionally, in the present study, ten nymphs of A. geayi were identified from B. tridactylus for the first time; nymphs of this species of tick had only been previously reported in the Brazilian Amazon region in Bradypus variegatus by MARTINS et al (2013) in the municipality of Belém, state of Pará.…”

Ticks are known worldwide for parasitizing a number of wild hosts. However, few studies have been conducted on ticks in zoos in Brazil. The objective of the present study was to collect, identify, and report the parasitic tick fauna found on wild Amazon animals received and attended at the Santarém Zoological Park from September 2004 to September 2013. In all, 56 animals, including 26 mammals and 30 reptiles, were sampled, from which 1172 ticks were collected and identified, comprising 862 adults, 284 nymphs, and 26 larvae. Nymphs of Amblyomma geayi on three-toed sloth (Bradypus tridactylus), adults of Amblyomma longirostre on black dwarf porcupine (Coendou nycthemera), and nymphs of Amblyomma naponense on southern tamandua (Tamandua tetradactyla) were identified for the first time in the country in the present study. Although, the North region is the largest among the five Brazilian regions, this is the first study conducted with ticks and animals attended in a zoo in the Brazilian Amazon.

“…Neumann (1899) described A. varium (variety albida) from an allegedly Chilean specimen. However, Chile is outside the range of the hosts (sloths of the families Bradypodidae and Megalonchydae) of A. varium (Marques et al 2002). We consider this finding a result of mislabelling rather than an indication of the presence of A. varium in Chile.…”

The tick species recorded from Chile can be listed under the following headings: (1) endemic or established: Argas keiransi Estrada-Peña, Venzal and Gonzalez-Acuña, A. neghmei Kohls and Hoogstraal; Ornithodoros amblus Chamberlin; Otobius megnini (Dugès); Amblyomma parvitarsum Neumann; A. tigrinum Koch; Ixodes auritulus Neumann; I. chilensis Kohls; I. cornuae Arthur, I. sigelos Keirans, Clifford and Corwin; I. stilesi Neumann; I. uriae White; Rhipicephalus sanguineus Koch. (2) Probably established or endemic: Argas miniatus Koch; Ornithodoros spheniscus Hoogstraal, Wassef, Hays and Keirans; Ixodes abrocomae Lahille; I. neuquenensis Ringuelet; I. pararicinus Keirans and Clifford. (3) Doubtfully established: Argas reflexus Fabricius; Ornithodoros talaje (Guérin-Méneville). (4) Exotic: Amblyomma argentinae Neumann; A. latum Koch, Rhipicephalus (= Boophilus) microplus (Canestrini). (5) Erroneously identified as present in Chile: Amblyomma americanum (Linnaeus); A. maculatum Koch; A. varium Koch; Ixodes conepati Cooley and Kohls; I. frontalis (Panzer); I. ricinus (Linnaeus); Margaropus winthemi Karsch. (6) Nomina nuda: Argas reticulatus Gervais; Amblyomma inflatum Neumann; Ixodes lagotis Gervais. Hosts and localities (including new records) are presented. Argas neghmei, O. amblus, O. megnini, I. uriae and R. sanguineus may cause severe injury to their hosts, including humans. The Chilean Ixodes fauna is unique to the Neotropical Zoogeographic Region, and additional research is needed in order to understand the biological importance of these species.

“…Although most of the tick-host reports cited in this study have been reported in earlier studies conducted in Brazil and in Argentina (FONSECA, 1933;ARAGÃO, 1936;LABRUNA et al, 2005LABRUNA et al, , 2007LABRUNA et al, , 2009MARTINS, J., et al, 2006;MARTINS, T., et al, 2009MARTINS, T., et al, , 2013MARTINS, T., et al, , 2015 (MARQUES et al, 2002). The present record of nymphs of A. varium on B. variegatus in the FPZSP is consistent with an earlier study which found that nymphs of this tick species use sloths of the genus Bradypus as hosts.…”

Ticks are ectoparasites of worldwide distribution that affect vertebrates and can transmit pathogens to animals and humans. The Zoological Park Foundation of São Paulo (FPZSP) is located in a Conservation Unit in one of the most important remaining fragments of the Atlantic Rainforest biome in the suburbs of São Paulo, Brazil. The FPZSP houses more than 3,000 wild animals on exhibit, in breeding programs and in environmental education programs, and also attracts migratory birds and free-roaming wildlife. This study focused on identifying the diversity of tick species that infest captive and free-roaming animals at the FPZSP. The collection of ticks kept at the FPZSP contains 523 specimens that were collected from different host species between 1990 and 2017. Ten tick species were found. In addition, Amblyomma aureolatum (Pallas) was found on stray cats living in the Atlantic forest fragment in the FPZSP. This study reveals a low occurrence of parasitism in captive animals and a high diversity of tick species collected from hosts in this Atlantic forest fragment, contributing information about host-parasite relationships and potential vectors of zoonotic diseases, since the vectors of Brazilian spotted fever, A. aureolatum and Amblyomma sculptum Berlese, were found in some hosts.
