ABSTRACT: The Wildlife Screening Center (CETAS) of the Tietê Ecological Park (PET), situated at the municipality of São Paulo, receives, treats and rehabilitates wild animals that have been dislodged from their natural environment due to different reasons. This study analyzed the ixodid fauna, and the rickettsial infection in these ticks, collected on wild animals received at the PET’s CETAS. During the period from March 2003 to November 2016, 936 ticks were collected from 96 wild animals (16 bird and 18 mammal species) that were sent to CETAS. The following 12 ixodid species were identified: Amblyomma aureolatum, Amblyomma brasiliense, Amblyomma calcaratum, Amblyomma dubitatum, Amblyomma longirostre, Amblyomma ovale, Amblyomma parkeri, Amblyomma sculptum, Amblyomma varium, Haemaphysalis juxtakochi, Ixodes loricatus and Rhipicephalus microplus. From 67 tick specimens tested by the Real Time PCR for rickettsiae, none were positive. The present research records for the first time in Brazil the following association between the tick stages and hosts that have never been reported before: Amblyomma sculptum nymphs on Caprimulgus parvulus, Asio clamator, Buteo brachyurus, Coragyps atratus, Amazona aestiva and Aramus guarauna, Amblyomma dubitatum nymphs on Alouatta guariba and Sphiggurus villosus, Amblyomma aureolatum adults on Bradypus variegatus, Amblyomma longirostre larvae and nymphs on A. clamator, and nymphs on Megascops choliba and Pyroderus scutatus, besides Amblyomma parkeri nymphs on Penelope obscura and Callicebus nigrifrons, and adult on Nasua nasua.
