RESUMO
Toxoplasmosis has been reported in many avian species, but little information is available from wild penguin populations. Leptospira can infects domestic and wild animals. Spheniscus magellanicus belong to the order Sphenisciformes, family Spheniscidae, and are colonial birds. These seabirds live in temperate waters along the Atlantic shores of South America, and their total population has been estimated to be 1,300,000 breeding pairs. Magdalena Island (Chile) hosts an important breeding colony but, over recent decades, a marked decline in the number of birds has been seen. The objective of this study was to determine occurrences of antibodies against T. gondii and Leptospira spp. in penguins (Spheniscus magellanicus) on Magdalena Island, from where no previous data on these agents were available. Serum samples were collected from 132 penguins on Magdalena Island. Antibodies against Toxoplasma gondii were detected using the modified agglutination test (Titer ≥20), and anti-Leptospira spp. antibodies were detected using the microscopic agglutination test (Titer ≥100). T. gondii antibodies were detected in 57 (43.18%) of the 132 serum samples, with titers that ranged from 20 to 320. None of the penguins in this study was reactive to anti-Leptospira spp. antibodies. This is the first report of T. gondii seropositivity in free-living Magellanic penguins in Chile.

O Zoológico Municipal de Guarulhos, localizado no estado de São Paulo, recebe e recupera animais silvestres do próprio município e de alguns municípios limítrofes. Entre os anos de 1997 e 2016 foram coletados carrapatos de animais silvestres (Cariama cristata, Buteo brachyurus, Alouatta guariba, Bradypus variegatus, Tamandua tetradactyla, Puma concolor, Cerdocyon thous, Nasua nasua, Mazama gouazoubira, Didelphis aurita, Sphiggurus villosus, Myocastor coypus e Hydrochoerus hydrochaeris) atendidos pelo Zoológico. Foram identificadas as seguintes espécies de carrapatos: Amblyomma aureolatum (Pallas, 1772), Amblyomma calcaratum Neumann, 1899, Amblyomma dubitatum Neumann, 1899, Amblyomma longirostre (Koch, 1844), Amblyomma nodosum Neumann, 1899, Amblyomma parkeri Fonseca e Aragão, 1952, Amblyomma sculptum Berlese, 1888, Amblyomma varium Koch, 1844, Haemaphysalis juxtakochi Cooley, 1946, Ixodes loricatus Neumann, 1899 e Rhipicephalus sanguineus sensu lato (Latreille, 1806). Apesar de todas as associações carrapato-hospedeiro já terem sido previamente relatadas no território brasileiro, o presente estudo registra pela primeira vez um ginandromorfo de A. dubitatum.

The Municipal Zoo of Guarulhos, located in the state of São Paulo, receives and recovers wild animals from the Guarulhos municipality and from some neighboring municipalities. Between the years of 1997 and 2016 ticks were collected on wild animals (Cariama cristata, Buteo brachyurus, Alouatta guariba, Bradypus variegatus, Tamandua tetradactyla, Puma concolor, Cerdocyon thous, Nasua nasua, Mazama gouazoubira, Didelphis aurita, Sphiggurus villosus, Myocastor coypus, and Hydrochoerus hydrochaeris) attended by the Zoo. The following tick species have been identified: Amblyomma aureolatum (Pallas, 1772), Amblyomma calcaratum Neumann, 1899, Amblyomma dubitatum Neumann, 1899, Amblyomma longirostre (Koch, 1844), Amblyomma nodosum Neumann, 1899, Amblyomma parkeri Fonseca and Aragão, 1952, Amblyomma sculptum Berlese, 1888, Amblyomma varium Koch, 1844, Haemaphysalis juxtakochi Cooley, 1946, Ixodes loricatus Neumann, 1899, and Rhipicephalus sanguineus sensu lato (Latreille, 1806). Although all tick-host associations have previously been reported in Brazilian territory, the present study records for the first time a gynandromorph of A. dubitatum.(AU)
