Estudo descritivo: histopatologia e imuno-histoquímica para a detecção de patógenos em amostras de fauna selvagem recebidas pelo Instituto Adolfo Lutz, Brasil

Objective: describe wild fauna casuistry data evaluated in 2019, in a reference laboratory in the State of São Paulo, Brazil, through histopathological and immunohistochemical analysis after the implementation of a pilot project of wildlife disease laboratory surveillance. Methods:descriptive study with survey of samples of non-human primates, birds and other mammals, received from two screening centers in the city of São Paulo. For this purpose, the referral forms and the issued histological and immunohistochemical reports were reviewed and data was tabulated and analysed by frequency and percentage distribution. Results: 233 animals of 20 distinct genera and/or species were received, being 191 (81,9%) non-human primates, 25 birds (10,7%) and 17 other mammals (7,3%); zoonotic pathogens were detected among the studied population, with a prevalence of bacterial conditions among the conclusive cases. Conclusion:histological and immunohistochemical analysis of wild fauna samples due the implementation of a wildlife disease laboratory surveillance pilot program contributed to the detection of some pathogens of public health relevance in São Paulo city, Brazil.

Ticks (Acari: Ixodidae) on wild raptors in Brazil

This research reports ticks on wild raptors in Brazil. Between the years 1936 and 2019, 127 larvae, 230 nymphs and 34 adult ticks were collected on 92 raptors (among 27 different species) from 35 localities in distinct Brazilian biomes. Additionally, an extensive literature review on ticks on wild raptors has been carried out, demonstrating that from 1993 to 2016, 29 larvae, 81 nymphs, 29 adults and 186 indeterminate immature ticks (larvae or nymphs) were collected on 41 raptors (16 different species) in 17 distinct localities in the Brazilian territory. The following tick species were identified on wild raptors in the country: Amblyomma aureolatum (Pallas, 1772), Amblyomma auricularium (Conil, 1878), Amblyomma brasiliense Aragão, 1908, Amblyomma cajennense (Fabricius, 1787) sensu stricto, Amblyomma calcaratum Neumann, 1899, Amblyomma coelebs Neumann, 1899, Amblyomma dubitatum Neumann, 1899, Amblyomma longirostre (Koch, 1844), Amblyomma nodosum Neumann, 1899, Amblyomma ovale Koch, 1844, Amblyomma parkeri Fonseca & Aragão, 1952, Amblyomma sculptum Berlese, 1888, Haemaphysalis juxtakochi Cooley, 1946, Rhipicephalus microplus (Canestrini, 1888), and Rhipicephalus sanguineus (Latreille, 1806) sensu lato. This study is therefore a significant contribution to our knowledge of the ticks associated with Brazilian raptors.
