Ticks have a great diversity of hosts, many of which are still being discovered. These parasites may be responsible for the transmission of several pathogens to animals and humans. For this reason, knowledge on tick species and their hosts is essential for planning actions in public health and fauna conservation. From February 2018 to July 2019, ticks found in animals treated at the Wild Animal Clinic of the Federal University of Lavras (UFLA) were surveyed. Animals came from nine municipalities at the southern region of Minas Gerais State, all close to the municipality of Lavras. During veterinary procedures the animals were inspected, and tick specimens were removed from the hosts’ skins with the help of tweezers, and posteriorly identified. One hundred and three specimens of ticks were removed from the hosts and allocated in five species of Amblyomma Koch, 1844 (Ixodidae) [A. nodosum (Neumann, 1899), A. sculptum Berlese, 1888, A. aureolatum (Pallas, 1772), A. calcaratum Neumann, 1899, and A. ovale (Koch, 1844)] and one of Rhipicephalus Latreille, 1806 [R. (Boophilus) microplus (Canestrini, 1888)]. Ticks were collected from: Cariama cristata (Linnaeus, 1766) (Cariamidae); Cerdocyon thous Linnaeus, 1766 and Chrysocyon brachyurus Illiger,1815 (Canidae); Leopardus pardalis Linnaeus, 1758 (Felidae); Mazama gouazoubira Fischer, 1814 (Cervidae); Myrmecophaga tridactyla Linnaeus, 1758 (Myrmecophagidae); Sphiggurus villosus (F. Cuvier, 1823) (Erethizontidae). In this study no new parasite-host relationships were found, however, wild animals can be vectors of important diseases, and monitoring the occurrence of ectoparasites in wildlife is a significant step in public health policies.

O grau de ameaça e a importância ecológica dos mamíferos terrestres de médio e grande porte evidenciam a necessidade da busca de informações em inventários e diagnósticos ambientais. Objetivo deste estudo foi inventariar e avaliar a freqüência de ocorrência e riqueza de espécies de mamíferos de médio e grande porte na Estação de Pesquisa, Treinamento e Educação Ambiental (EPTEA) Mata do Paraíso, em Viçosa - MG. A área de estudo foi aleatoriamente percorrida, em busca de evidências indiretas e diretas de mamíferos. Também foram utilizadas armadilhas Tomahawk e fotográficas para o registro e identificação das espécies. Para registrar a freqüência de ocorrência, estabeleceu-se 20 parcelas de 2 x 2 m ao longo de um transecto, as quais foram vistoriadas 29 vezes entre abril de 2005 e abril de 2006. A partir dos dados de freqüência de ocorrência, estimou-se a riqueza de espécies, pelo procedimento Jackknife 1, utilizando o Programa EstimateS. Foram registradas 23 espécies de mamíferos, das quais três estão ameaçadas de extinção: Chrysocyon brachyurus (Illiger, 1815), Leopardus pardalis (Linnaeus, 1758) e Leopardus tigrinus (Schreber, 1775). As espécies silvestres com maior freqüência de registro foram Cerdocyon thous (Linnaeus, 1766), L. tigrinus e L. pardalis. Foi estimada a riqueza de 15 (intervalo de confiança = 0,95) espécies de mamíferos terrestres silvestres para a EPTEA Mata do Paraíso. O presente trabalho mostra que apesar de pequena, a área de estudo desempenha um importante papel na conservação da mastofauna da região de Viçosa - MG.

Dermatophytes are keratinophilic fungi that can cause zoonosis. However, the role wild animals play in the transmission of these infections is yet to be determined. The aim of this study was to determine the presence of dermatophytes on the haircoat of Brazilian wild mammals. Thirty-two healthy wild mammals from several taxa were studied: 17 were captive and 15 were free-living individuals. Samples were obtained by rubbing the haircoat with sterile carpets. Samples were cultured on Mycobiotic agar, and the plates were incubated at 25 ºC. Identification of the isolates was carried out on the basis of macro- and micromorphology. Dermatophytes were isolated from 9.5% of the animals: Microsporum gypseum from one maned wolf (Chrysocyon brachyurus), Microsporum cookie from one coati (Nasua nasua), and Trichophyton ajelloi from one bush dog (Speothos venaticus). These animals represent therefore sources of infection for both humans and other animals and are important for public health policies.

The aims of this study were to evaluate the seasonal variation and frequency distribution of Rhipicephalus (Boophilus) microplus, Haematobia irritans, and Dermatobia hominis on crossbred heifers under field conditions in the northeast of Minas Gerais state, southeastern Brazil. From November 2007 to September 2009 (23 months), 40 heifers aged 16.6±2.4 months were divided into groups A (1/4 Holstein × 3/4 Gir) and B (1/2 Holstein × 1/2 Gir) and had the monthly infestation estimated along with the climatic conditions. The mean maximum and minimum temperatures were 28.5 and 19°C, respectively. The ectoparasites were present on animals in all months of the year. The levels of ticks on the animals were low (3.0±0.2 ticks/animal), with the highest density in midwinter. The temperature was the climatic factor that most influenced the tick levels. The population of H. irritans (13.9±0.3 flies/animal) and D. hominis (1.5±0.2 larvae/animal) on heifers was more influenced by rainfall and exhibited two population peaks during the year. 1/2 Holstein heifers harbored significantly more H. irritans and D. hominis than 1/4 Holstein heifers. The results are discussed considering the most appropriate periods to apply ectoparasiticides and the genetic make-up of the animals.

Solanum lycocarpum A. St-Hil (wolf’s fruit or lobeira) (Solanaceae) is a perennial shrub typical of the Brazilian Cerrado (savanna), under constant cutting and burning due to anthropic activities for the development of agricultural and livestock farming. It presents therapeutic medicinal attributes for humans and wild animals primarily as an anthelmintics. Little is known about the insect fauna associated with S. lycocarpum, and no study has been conducted on the true bugs (Heteroptera) associated with it. For the study, the true bugs were sampled from ten points in the mesoregion of Triangulo Mineiro and Alto Paranaiba for one year in two seasonal periods of drought and rain. In each locality, 20 shrubs of S. lycocarpum were selected.

Abstract: The Brazilian savanna, also known as Cerrado, is one of the world's richest and most ecologically invaluable tropical savanna regions. There are few studies in Brazil about the diseases that affect the wild canids of this biome, which may be harmful to wildlife populations and public health. The aim of this study was to evaluate the occurrence of antibodies against Leptospira spp. in three Cerrado wild canids species using the microscopic agglutination test (MAT). Serum samples were tested from 19 crab-eating foxes (Cerdocyon thous), 14 maned wolves (Chrysocyon brachyurus), and seven hoary foxes (Lycalopex vetulus), all free-ranging animals found in the municipalities of Araguari and Uberlândia, Minas Gerais State, and Cumari, Goiás State, Brazil. Fourteen (35%) of these samples were seropositive. The most frequent serovars detected in the samples were Copenhageni and Hardjo, but reactions to the serovars Autumnalis, Grippotyphosa, Hebdomadis, Wolffi, and Icterohaemorrhagiae also occurred. Notwithstanding other reported results, this study is the first to report the presence of antibodies against Leptospira spp. in L. vetulus. The three species of wild canids examined may act as potential hosts for several serovars of leptospira in Brazil's savanna environment.

We present a species list of the mammals of the Estação Ecológica do Panga, a 404 ha Cerrado reserve in Minas Gerais state, Brazil. Using methods ranging from camera traps to direct observations, we documented 46 species in the reserve. Among medium and large-sized mammals, the order Carnivora was the most commonly observed (N=12 species). The highest relative frequencies of observation were of Mazama guazoubira and Cerdocyon thous. Pecari tajacu was the most frequent species in camera traps. Over the course of 7320 trap nights there were 105 captures of small mammals from seven species, with an overall capture rate of 1.6 %. The highest capture rates were for the marsupial Gracilinanus agilis, with Calomys tener the most commonly caught rodent. Our survey suggests that many of the Cerrado’s mammal species can persist in landscapes that are a mosaic of natural areas and some types of agriculture.

Animal Control

City-scale urban greening is expanding wildlife habitat in previously less hospitable urban areas. Does this transformation also prompt a reckoning with the longstanding idea that cities are places intended to satisfy primarily human needs? I pose this question in the context of one of North America's most ambitious green infrastructure programmes to manage urban runoff: Philadelphia's Green City, Clean Waters. Given that the city's green infrastructure plans have little to say about wildlife, I investigate how wild animals fit into urban greening professionals' conceptions of the urban. I argue that practitioners relate to urban wildlife via three distinctive frames: 1) animal control, 2) public health and 3) biodiversity, and explore the implications of each for peaceful human-wildlife coexistence in 'greened' cities.
