1. SURVEILLANCE FOR NEWCASTLE DISEASE VIRUS, AVIAN INFLUENZA VIRUS AND MYCOPLASMA GALLISEPTICUM IN WILD BIRDS NEAR COMMERCIAL POULTRY FARMS SURROUNDED BY ATLANTIC RAINFOREST REMNANTS, SOUTHEASTERN BRAZIL
ABSTRACT The geographic overlap between areas of Atlantic rainforest and human activities allows interactions to occur between humans and wild and domestic animals. Despite the great importance of the domestic animal-wildlife-human interface that occurs at poultry farms in terms of public health, economic production and wildlife conservation, there are few s

2. Host preference of the hemiparasite Struthanthus flexicaulis (Loranthaceae) in ironstone outcrop plant communities, southeast Brazil
Struthanthus flexicaulis is a hemiparasite abundant in ironstone outcrops in southeast Brazil. We evaluated its host preference among species of the plant community, taking into account the abundance and foliage cover of the hosts. The importance of each species in the community and the mortality caused by the parasite were assessed based on a quantitative s

3. Richness, composition and trophic groups of an avian community in the Pernambuco Endemism Centre, Alagoas, Brazil
No Nordeste do Brasil, a redução da cobertura florestal original a pequenos fragmentos isolados tem trazido consequências negativas para a avifauna local, em particular, uma perda de espécies mais especializadas e o aumento populacional de algumas espécies generalistas. O presente estudo foca na composição e nos grupos tróficos de uma comunidade de a

4. Efeito do manejo de fogo sobre comunidades de aves em campos sujos no Parque Nacional das Emas, GO/MS, Cerrado Central / Effects of fire management on birds in Emas National Park, Brazil, Central Cerrado
Several studies have investigated the effects of natural fires on Cerrado birds. However, avian responses to fire management have not been examined. We compared birds found in firebreaks (fire managed areas) and in fire unmanaged grasslands, in Parque Nacional das Emas, Central Brazil. This is the first study to evaluate the effects of prescribed fire on the

5. Artificial nest predation: application, challenges and perspectives for the tropical areas / Predação de ninhos artificiais: aplicações, desafios e perspectivas para as áreas tropicais
The natural predation of the nests has been suggested as the principal cause to the decline of bird population, acting on the performance and community structure. Due to the difficulty of natural nest localization and monitoring, the artificial nests are used as a fast alternative to check the avian reproductive success. The artificial nest studies are widel

6. Estrutura e organização de comunidades de aves em areas da Mata Atlantica primitiva e explorada por corte seletivo
The purpose of this study was to evaluate the effects of selective logging on a bird community in the Brazilian Atlantic forest. Two areas were selected for avian surveys, both qualitative (presence-absence) and quantitative (censuses): a non-fragmented primary forest (designated M1) and, very near to it (500 m), a selectively logged forest (designated M2).

7. Probiotics Shown To Change Bacterial Community Structure in the Avian Gastrointestinal Tract
Culturing and molecular techniques were used to monitor changes in the bacterial flora of the avian gastrointestinal (GI) tract following introduction of genetically modified (GM) and unmodified probiotics. Community hybridization of amplified 16S ribosomal DNA demonstrated that the bacterial flora of the GI tract changed significantly in response to the pro

8. Transfection of Chicken Embryo Cells with DNA Extracted from Avian Virus-Producing Neoplastic Cells
DNA isolated from avian virus-producing leukemic myeloblasts induced the production of viruses, but not morphological transformation, in cultivated chicken fibroblasts. The recovered virus had the same biological characteristics as the original avian myeloblastosis virus (AMV) and produced myeloblastosis and nephroblastomas when injected into chickens. Neutr

9. Host population persistence in the face of introduced vector-borne diseases: Hawaii amakihi and avian malaria
The past quarter century has seen an unprecedented increase in the number of new and emerging infectious diseases throughout the world, with serious implications for human and wildlife populations. We examined host persistence in the face of introduced vector-borne diseases in Hawaii, where introduced avian malaria and introduced vectors have had a negative

10. Emergence and Dissemination of Quinolone-Resistant Escherichia coli in the Community
We studied the evolution of resistance to quinolones in Escherichia coli from 1992 to 1997 in Barcelona, Spain. An increasing proportion of quinolone-resistant E. coli (QREC) infections was observed. QREC strains were more common in patients with nosocomial infections but also increased in patients with community-acquired infections (9% in 1992 to 17% in 199

11. Recent human-to-poultry host jump, adaptation, and pandemic spread of Staphylococcus aureus
The impact of globalization on the emergence and spread of pathogens is an important veterinary and public health issue. Staphylococcus aureus is a notorious human pathogen associated with serious nosocomial and community-acquired infections. In addition, S. aureus is a major cause of animal diseases including skeletal infections of poultry, which are a larg

12. Research preparedness paves the way to respond to pandemic H1N1 2009 influenza virus
The international community has been preparing for an influenza pandemic because of the threat posed by H5N1 avian influenza. Over the past several years, Canada has dedicated funding to boost capacity for research, and public health and health care system readiness and response in the event of a pandemic. The current H1N1/09 influenza pandemic is now testin
