1. Lytic bacteriophages as a potential alternative to control Staphylococcus aureus
Resumo: O objetivo deste trabalho foi caracterizar bacteriófagos autóctones e determinar sua atividade lítica em Staphylococcus aureus. Seis fagos foram isolados de água de lavagem de pisos de estábulos por meio do enriquecimento de cultura com três estirpes de S. aureus. Todos os fagos foram caracterizados pela digestão do DNA com enzimas de restriç

2. Autochthonous microalgae cultivation with anaerobic effluent: isolation of strains, survivorship, and characterization of the produced biomass
Resumo Seis cepas de Chlorophyta foram isoladas do efluente de um reator anaeróbio tratando esgoto sanitário e identificadas como Desmodesmus sp. L02, Chlorococcum sp. L04, Coccomyxa sp. L05, Chlorella sp. L06, Scenedesmus sp. L08 e Tetradesmus sp. L09. As cepas de microalgas foram cultivadas em efluente não-esterilizado em condições de laboratório par

3. Efficacy of leptospiral commercial vaccines on the protection against an autochtonous strain recovered in Brazil
Abstract In swine and bovines, leptospirosis prevention and control is carried out via vaccination of susceptible animals using bacterins. However, the efficiency of leptospirosis vaccines has been questioned. This work aimed to investigate the potency of five leptospirosis vaccines sold commercially in Brazil, challenging the animals with one autochthonous

4. Development of an autochthonous starter culture for spreadable goat cheese
Abstract The aim of this work was to select strains of LAB autochthonous from Santiago del Estero to formulate a starter culture for making spreadable goat cheese. Four strains were selected: CRL1799 (Lactobacillus fermentum with high acidifying activity), CRL1803 (Lactobacillus fermentum with high proteolytic activity), CRL1808 (Lactobacillus rhamnosus with

5. Effect of Leishmania spp infection on the survival, life expectancy, fecundity and fertility of Lutzomyia longipalpis s.l. and Lutzomyia pseudolongipalpis
We evaluated the effects of Leishmania spp infection on several population parameters of Lutzomyia longipalpis sensu lato and Lutzomyia pseudolongipalpis, vectors of visceral leishmaniasis in Venezuela, under experimental conditions during the first post-feeding period. Females of both species were allowed to feed and engorge on a suspension of fresh washed

6. Emprego de estirpes de leptospiras isoladas no Brasil, na microtécnica de soroaglutinação microscópica aplicada ao diagnóstico da leptospirose em rebanhos bovinos de oito estados brasileiros / Use of strains of leptospires isolated in Brazil, for the microscopic agglutination test applied to the diagnosis of leptospirosis in bovine herds of eight Brazilian states
Bovine leptospirosis is one of the main reproductive diseases which interferes economically on the livestock and thus it is needed the amelioration of the laboratory diagnostic procedures. The aim of this work is to investigate the adequacy to use autochthonous strains of leptospires isolated in Brazil, added into the antigen collection applied for the micro

7. Autochthonous horizontal transmission of a CRF02_AG strain revealed by a human immunodeficiency virus type 1 diversity survey in a small city in inner state of Rio de Janeiro, Southeast Brazil
As part of an ongoing study on the features of AIDS spread towards small cities and rural areas, we present a molecular survey of human immunodeficiency virus type 1 (HIV-1) polymerase sequences recovered between 2004 and 2006 from 71 patients receiving care in the city of Saquarema, inner state of Rio de Janeiro. Phylogenetic reconstructions found the two p

8. A associação entre o zooplâncton e Vibrio cholerae O1 e O139 no complexo estuarino de Santos - Bertioga e Plataforma adjacente / The association between zooplankton and Vibrio cholerae O1 and O139 on Santos-Bertioga estuarine system and adjacent shelf
Vibrio cholerae is an autochthonous bacterium in the sea and may cause serious health problems when pathogenic strains are accidentally ingested. V. cholerae are found associated with copepods in concentrations up to a thousand times higher than the free bacteria in the water. If ingested, a single copepod may have enough bacteria necessary for human infecti

9. Molecular Epidemiology of the virus of the imunodeficiência human being type 1 (HIV-1) in cities of the interior of the State of Rio de Janeiro, with emphasis in the cities of Miracema, Santo Antonio de Pádua and Saquarema, 2001 the 2006. / Epidemiologia Molecular do Vírus da Imunodeficiência Humana Tipo 1 (HIV-1) em Municípios do Interior do Estado do Rio de Janeiro, com Ênfase nas Cidades de Miracema, Santo Antonio de Pádua e Saquarema, 2001 a 2006.
The AIDS epidemic in Brazil is spreading from the large urban centers to small cities and the innermost parts of the country, yet data on the features of HIV-1 infection in these places are scarce. Such spread is expected to pose formidable medical, social and logistic challenges. By using mainly HIV-1 envelope and polymerase genomic regions, the studies tha

10. Emerging acute Chagas Disease in Amazonian Brazil: case reports with serious cardiac involvement
Four cases of serious cardiac attacks by autochthonous Trypanosoma cruzi infection from the Brazilian Amazon are reported; three of them occurred in micro-epidemic episodes. The manifestations included sudden fever, myalgia, dyspnea and signs of heart failure. Diagnosis was confirmed by specific exams, especially QBC (Quantitative Buffy Coat) and natural xen

11. Genetic characterization of dengue virus type 3 isolates in the State of Rio de Janeiro, 2001
The genetic characterization of dengue virus type 3 (DEN-3) strains isolated from autochthonous cases in the State of Rio de Janeiro, Brazil, in 2001 is presented. Restriction site-specific (RSS)-PCR performed on 22 strains classified the Brazilian DEN-3 viruses as subtype C, a subtype that contains viruses from Sri Lanka, India, Africa and recent isolates f

12. Caracterização biologica e morfologica da linhagem paulista de Schistosoma mansoni da região de Campinas, SP
The São Paulo State ( Brazil ) shows autochtonous schistosomiasis mansom in several regions, including the region of Campinas. This suggests a possible development of this disease during the last three years. The present work was elaborate having in view to determine biological characteristics of Schistosoma mansoni recently isolated trom the Ward São Domi
