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.

Recebimento de apuim-de-costas-pretas, Touit melanonotus (Aves: Psittacidae) no Centro de Recuperação de Animais Silvestres do Parque Ecológico do Tietê, São Paulo

O apuim-de-costas-pretas (Touit melanonotus), é um psitacídeo neotropical de pequeno porte, que vive aos pares ou em grupos e encontra-se ameaçado de extinção. Em março de 2020, um bando com 33 indivíduos de T. melanonotus foi entregue pela equipe de resgate de fauna do Aeroporto Internacional de São Paulo no Centro de Recuperação de Animais Silvestres do Parque Ecológico do Tietê (CRAS-PET), após colidir contra vidraça.

Occurrence of parasitism by Dioctophyma renale in ring-tailed coatis (Nasua nasua) of the Tiete Ecological Park, São Paulo, Brazil

Dioctophymosis is a worldwide renal parasitosis caused by the Dioctophyma renale nematode, which results in progressive destruction of renal tissue. Aquatics annelids are considered the main intermediate hosts and the literature refers as permanent hosts of dogs, wild mammals and even humans. During procedures for population control of coatis (Nasua nasua) in the Ecological Park of Tietê (PET), was noticed the presence of parasitosis by D. renale. From 68 animals, males and females, young and adults, submitted to exploratory laparotomy, 51 were positive for the presence of worms, 9 were found only in the right kidney. In 10 cases, in addition to right kidney parasitism, worms were also observed in the abdominal cavity. In 24 cases D. renale was found only in the abdominal cavity and in 8 animals the right kidney was reduced to a small rigid structure. The study showed that the preferred site for parasitism of the worm, considered erratic, was the abdominal cavity in 66.66% of the cases.
