RESUMO: Muitas espécies de animais silvestres de vida livre servem como reservatório de bactérias patogênicas que ameaçam a saúde humana e dos animais domésticos. Algumas bactérias, como Campylobacter jejuni, Campylobacter coli, Yersinia enterocolitica e Salmonella enterica, causam enfermidades em humanos e podem contaminar os animais domésticos e silvestres. O Núcleo de Reabilitação da Fauna Silvestre da Universidade Federal de Pelotas (NURFS-UFPel) soluciona uma demanda regional específica de atenção à fauna silvestre brasileira. O objetivo desse trabalho foi identificar a presença de Campylobacter jejuni, Campylobacter coli, Salmonella spp. e Yersinia enterocolitica em animais silvestres que se encontravam em processo de reabilitação. Foram coletadas amostras de fezes, com uso de zaragatoas estéreis, de 34 aves, 16 mamíferos e 23 répteis. Dos 73 animais amostrados, quatro (5,48%) albergavam Y. enterocolitica, sendo duas aves, um mamífero e um réptil. Salmonella e Campylobacter não foram isolados. Os perfis de bandas dos isolados de Y. enterocolitica analisados pela rep-PCR foram diferentes entre si. Esses resultados indicam que as cepas isoladas não estão relacionadas entre si, não possuindo uma origem comum recente. Vanellus chilensis, Turdus rufiventris, Didelphis albiventris e Pantherophis guttatus podem albergar Y. enterocolitica e eliminá-la nas fezes, oferecendo risco de disseminação desse micro-organismo no ambiente, além de constituírem possíveis fontes de contaminação para humanos e outros animais.

Pleistocene Deposit

The present study acknowledges the diversity of fossil marsupials from the Gruta dos Moura cave, as well as environmental and climatic aspects during the Quaternary. The results show that this is the largest diversity of Pleistocene marsupials recorded in a single cave: Didelphis albiventris, D. aurita, Gracilinanus agilis, G. microtarsus, Marmosa murina, Monodelphis brevicaudata, M. domesticaand Sairadelphys tocantinensis. Furthermore, the described specimens are also part of the only fossil assemblage unequivocally referable to the late Pleistocene. Paleontological studies suggest an intimate association with dry and open environments with high abundance of water sources. Since most of the identified taxa are characteristic of open forests and gallery forests, this could represent the actual environment around the Gruta dos Moura cave. Recent studies identified sympatric occurrences between species from open and dry environments and species from humid forests that were identified among our material and are characteristic of humid regions. Therefore, these species could inhabit gallery forests and capons, or even ecotones, inside a dry and open environment. Moreover, the extinction of Sairadelphyscould also indicate that the climatic and environmental conditions changed or that the past environment was more heterogeneous than the current environment of the region.

Each animal species selects specific microhabitats for protection, foraging, or micro-climate. To understand the distribution patterns of small mammals on the ground and in the understorey, we investigated the use of microhabitats by small mammals in a deciduous forest of southern Brazil. Ten trap stations with seven capture points were used to sample the following microhabitats: liana, fallen log, ground litter, terrestrial ferns, simple-trunk tree, forked tree, and Piper sp. shrubs. Seven field phases were conducted, each for eight consecutive days, from September 2006 through January 2008. Four species of rodents (Akodon montensis, Sooretamys angouya, Oligoryzomys nigripes and Mus musculus) and two species of marsupials (Didelphis albiventris and Gracilinanus microtarsus) were captured. Captured species presented significant differences on their microhabitat use (ANOVA, p = 0.003), particularly between ground and understorey sites. Akodon montensis selected positively terrestrial ferns and trunks, S. angouya selected lianas, D. albiventris selected fallen trunks and Piper sp., and G. microtarsus choose tree trunks and lianas. We demonstrated that the local small-mammal assemblage does select microhabitats, with different types of associations between species and habitats. Besides, there is a strong evidence of habitat selection in order to diminish predation.

We evaluated the role of communities of small mammals from three distinct areas in a region of Cerrado mixed with Atlantic Forest remains for maintenance of tick fauna. Thirty-nine marsupials (Gracilinanus agilis, n = 34; Marmosa paraguaiana, n = 4; Didelphis albiventris, n = 1) and 33 rodents (Oecomys cleberi, n = 10; Nectomys squamipes, n = 4; Calomys tener, n = 4; Hylaeamys megacephalus, n = 4; Akodon sp., n = 3; Rattus rattus, n = 3; Cerradomys subflavus, n = 2; Mus musculus, n = 2; Rhipidomys macrurus, n = 1) were captured. Solely G. agilis and the four rodent species (N. squamipes, R. macrurus, C. subflavus and Akodon sp.) were infested. Four tick species were collected (Amblyomma dubitatum, Amblyomma sculptum, Ixodes loricatus and Ornithodoros mimon). A. dubitatum was the most abundant tick species on hosts. Capture success was higher in the dry season, but the infestation was similar in both seasons. Forested habitats, particularly riparian forests, resulted in higher number of hosts and ticks collected (from hosts and from vegetation), compared to pastures and anthropized sites. The association between C. subflavus and I. loricatus and between A. dubitatum and N. squamipes observed here is the first recorded in Cerrado biome. Areas with more patches of forest, including the Atlantic Forest fragments, tend to present a richest community of small mammals and associated ticks.
