1. Molecular survey of tick-borne pathogens in small mammals from Brazilian Amazonia
Resumo Pequenos mamíferos não voadores (marsupiais e pequenos roedores) foram capturados em três diferentes períodos, ao longo de 23 fragmentos florestais de três municípios (Alta Floresta, Sinop e Cláudia), localizados no bioma amazônico do Estado de Mato Grosso, no centro-oeste do Brasil. Os tecidos dos animais (fígado e baço) e sangue foram sele

2. Detection of Hemotropic Mycoplasma sp. in white-eared opossums (Didelphis albiventris) from Southern Brazil
Resumo Gambás são marsupiais do Novo Mundo, pertencentes ao gênero Didelphis, e considerados animais sinantrópicos devido à sua proximidade com seres humanos. Atualmente, a espécie ‘Candidatus Mycoplasma haemodidelphis’ só foi encontrada infectando gambá norte americano (Didelphis virginiana). O objetivo do presente estudo foi detectar a infecç�

3. Trypanosoma cruzi strain TcIV infects raccoons from Illinois
BACKGROUND The northern limits of Trypanosoma cruzi across the territory of the United States remain unknown. The known vectors Triatoma sanguisuga and T. lecticularia find their northernmost limits in Illinois; yet, earlier screenings of those insects did not reveal the presence of the pathogen, which has not been reported in vectors or reservoir hosts in

4. INFECTION BY Rickettsia felis IN OPOSSUMS (Didelphis sp.) FROM YUCATAN, MEXICO
Rickettsia felis is an emergent pathogen and the causative agent of a typhus-like rickettsiosis in the Americas. Its transmission cycle involves fleas as biological vectors (mainly Ctenocephalides felis) and multiple domestic and synanthropic mammal hosts. Nonetheless, the role of mammals in the cycle of R. felis is not well understood and many efforts are o

5. Are opossums a relevant factor associated with asymptomatic Leishmania infection in the outskirts of the largest Brazilian cities?
Abstract A population survey was conducted to explore the prevalence and factors associated with Leishmania infection in the Fercal region of the Federal District. The Fercal region is a group of neighborhoods in Brasília in which the first cases of visceral leishmaniasis were described. Leishmania infection was established by a positive leishmanin test. Al

6. Investigação de anticorpos contra Sarcocystis neurona e Sarcocystis cruzi em equinos
ABSTRACTSarcocystis neurona is the primary agent for Equine Protozoal Myeloencephalitis (EPM), important neurological disease characterized by behavior or muscular changes, that impairs animal performance and husbandry. Sarcocystis cruzi is a pathogen related to myositis in cattle. Although related the life cycles of the parasites are distinct. S. neurona ha

7. Geographic variation in Caluromys derbianus and Caluromys lanatus (Didelphimorphia: Didelphidae)
We analyzed the geographic variations in the shape and size of the cranium and mandible of two woolly opossums, Caluromys derbianus and Caluromys lanatus. Using geometric morphometrics we analyzed 202 specimens of C. derbianus and 123 specimens of C. lanatus, grouped in 7 and 9 populations, respectively. We found sexual dimorphism in shape variables only in

8. Eclectic feeding behavior of Lutzomyia (Nyssomyia) intermedia (Diptera, Psychodidae, Phlebotominae) in the transmission area of American cutaneous leishmaniasis, state of Paraná, Brazil
Introduction The blood meal source of sandflies provides valuable information about the vector/host interaction and allows for an understanding of American cutaneous leishmaniasis (ACL) transmission mechanisms. The aim of this study was to identify the blood meal sources of Lutzomyia (Nyssomyia) intermedia in an endemic area of leishmaniasis in Brazil's St

9. Evaluation of natural foci of Panstrongylus megistus in a forest fragment in Porto Alegre, State of Rio Grande do Sul, Brazil
Introduction Panstrongylus megistus is commonly found in wild environments of the State of Rio Grande do Sul, Brazil. The aim of this study was to characterize the network of refuges used by triatomine in a forest fragment of Porto Alegre and to identify Trypanosoma cruzi infection, associated hosts and the epidemiological importance of both hosts and tria

10. A artéria celíaca em Didelphis albiventris (gambá) = The celiac artery in Didelphis albiventris (opossum) / The celiac artery in Didelphis albiventris (opossum)
Background: This member of the Didelphidea family, commonly known as opossum, is widely distributed in the American territory, with species found from southern Canada up to northern Argentina. Similarly to all marsupials, they are characterized by a short gestational period, followed by a long development period. Opossums are arboreal, terrestrial slow anima

11. The community of medium and large mammals in fragments of Atlantic Forest in the environmental protected area of Campinas, São Paulo state / Comunidade de mamiferos de medio e grande porte em fragmentos de mata semidecidual da APA municipal de Campinas, SP
I evaluated the medium and large mammal community in 13 small fragments (1 to 12ha) and a control (220ha) in the Environmental Protected Area of Campinas, São Paulo state. The community was sampled using baited track stations (Pro s Choice and Canine Call bait) over a year (once each quarter) from July 2007 to June 2009, giving 15 to 170 track-station night

12. Hyper abundant mesopredators and bird extinction in an Atlantic forest island
Islands can serve as model systems for understanding how biological invasions affect native species. Here we examine the negative effects of mesopredator mammals on bird richness at Anchieta Island, an 826 ha offshore island in the coast of Brazil. Anchieta Island has the highest density of mammals of the entire Atlantic forest, especially nest predators suc
