Arboviroses são grave problema de saúde pública no Brasil e destas destacam-se aquelas causadas por Flavivírus, dos quais onze já foram descritos no Brasil. Destes, dois importantes em saúde pública, e que pertencem ao sorocomplexo da Encefalite Japonesa, são o vírus da encefalite de Saint Louis (SLEV) e o Rocio (ROCV). O vírus Oeste do Nilo (WNV), introduzido no continente americano em 1999, ainda não foi detectado no Brasil, contudo sua introdução é muito provável. Neste estudo, avaliou-se a circulação de SLEV, ROCV e WNV em cavalos, por tentativas de isolamento viral e inquérito soro-epidemiológico. As tentativas de isolamento viral, em 11 tecidos cerebrais de cavalos do estado da Paraíba, resultaram negativas. O inquérito sorológico, por IgG-ELISA tendo como antígeno peptídeos recombinantes do domínio III da proteína de envelope de SLEV, WNV e ROCV, foi utilizado em 753 soros de animais dos estados de São Paulo, Mato Grosso do Sul, Minas Gerais, Rio de Janeiro e Paraíba. Soros de 271 cavalos foram positivos para SLEV (35,98%), 254 para WNV (33,73%) e 144 para ROCV (19,12%). Portanto, o ELISA mostrou-se adequado, diagnosticando infecções prévias por estes Flavivírus. Também, observou-se intensa circulação destes vírus infectando cavalos nos locais de estudo. Ainda...

O objetivo deste trabalho é identificar os modelos de realeza em Luís IX, rei da França entre 1226 e 1270, tendo como base principalmente a obra de Jean de Joinville intitulada Histoire de Saint Louis. No decorrer da análise, constata-se o caráter peculiar do documento como espelho de príncipe, gênero medieval que procura estabelecer um modelo ideal de realeza. Luís IX é nele retratado como um rei peregrino, cruzado que ampliou o reino de Deus na terra, buscando identificá-lo ao reino de Cristo, à Imitatio Christi. Joinville, senescal de Champagne, descreveu nessa obra grande parte da vida do rei, memórias resgatadas trinta anos depois de sua morte. Escrita de 1305 a 1309, a pedido de Joana de Navarra (1270-1305), esposa de Filipe o Belo (1268-1314), seu objetivo seria de enaltecer as palavras santas e as boas realizações do rei, que se tornaria São Luís. Escolheu-se este documento sobretudo por seu caráter de particular autoria, visto que Joinville, na condição de senescal laico, amigo e confidente do rei, narrou um longo período do governo do seu rei e senhor de um ponto de vista privilegiado. Uma característica muito marcante da monarquia capetíngia e do reinado de Luís IX especificamente foi a forte aliança com a Igreja. A Igreja era peça mestra do sistema feudal e sua justificadora ideológica...

Tanto o Pavilhão Brasileiro da Exposição de Saint Louis, ocorrido em 1904, de autoria do engenheiro Francisco Marcelino de Souza Aguiar, como o da Feira de Nova York, de 1939, dos arquitetos Lucio Costa e Oscar Niemeyer, carregavam a missão arquitetônica de representar a identidade do país. Manifestaram-se distintos em suas arquiteturas pela formação de seus autores e pelo lugar e época em que foram construídos. Esses edifícios revelam dimensões da vida nacional em ressonância com as relações políticas, comerciais e culturais tecidas para a sua realização. O conjunto de circunstâncias sobre as quais essas arquiteturas se fundamentam contraria suas aparentes oposições e lhes confere sentidos complementares. Uma construção diplomática que transpôs percalços políticos, conciliando-os para um projeto de modernização e superação do país frente aos passados recentes de cada um dos períodos. Esse trabalho diplomático estreitou relações da jovem República do Brasil com os EUA, paradigma de nação nova que reunia as condições materiais e tecnológicas para a construção dos dois pavilhões. Tomar esses dois casos como exemplares permite compreender os aspectos de diálogo entre tradições europeias e suas emulações americanas. Caminhos complementares da arquitetura e da diplomacia revelam as vontades correntes de modernização e da busca do estabelecimento de maioridade do país...

Introduction Saint Louis encephalitis virus (SLEV) primarily occurs in the Americas and produces disease predominantly in humans. This study investigated the serological presence of SLEV in nonhuman primates and horses from southern Brazil. Methods From June 2004 to December 2005, sera from 133 monkeys (Alouatta caraya, n=43; Sapajus nigritus, n=64; Sapajus cay, n=26) trap-captured at the Paraná River basin region and 23 blood samples from farm horses were obtained and used for the serological detection of a panel of 19 arboviruses. All samples were analyzed in a hemagglutination inhibition (HI) assay; positive monkey samples were confirmed in a mouse neutralization test (MNT). Additionally, all blood samples were inoculated into C6/36 cell culture for viral isolation. Results Positive seroreactivity was only observed for SLEV. A prevalence of SLEV antibodies in sera was detected in Alouatta caraya (11.6%; 5/43), Sapajus nigritus (12.5%; 8/64), and S. cay (30.8%; 8/26) monkeys with the HI assay. Of the monkeys, 2.3% (1/42) of A. caraya, 6.3% 94/64) of S. nigritus, and 15.4% (4/26) of S. cay were positive for SLEV in the MNT. Additionally, SLEV antibodies were detected by HI in 39.1% (9/23) of the horses evaluated in this study. Arboviruses were not isolated from any blood sample. Conclusions These results confirmed the presence of SLEV in nonhuman primates and horses from southern Brazil. These findings most likely represent the first detection of this virus in nonhuman primates beyond the Amazon region. The detection of SLEV in animals within a geographical region distant from the Amazon basin suggests that there may be widespread and undiagnosed dissemination of this disease in Brazil.

Saint Louis encephalitis virus caused an outbreak of febrile illness and encephalitis cases in Córdoba, Argentina, in 2005. During this outbreak, the strain CbaAr-4005 was isolated from Culex quinquefasciatus mosquitoes. We hypothesised that this epidemic variant would be more virulent in a mouse model than two other non-epidemic strains (78V-6507 and CorAn-9275) isolated under different epidemiological conditions. To test this hypothesis, we performed a biological characterisation in a murine model, including mortality, morbidity and infection percentages and lethal infection indices using the three strains. Mice were separated into age groups (7, 10 and 21-day-old mice) and analysed after infection. The strain CbaAr-4005 was the most infective and lethal of the three variants, whereas the other two strains exhibited a decreasing mortality percentage with increasing animal age. The strain CbaAr-4005 produced the highest morbidity percentages and no significant differences among age groups were observed. The epidemic strain caused signs of illness in all inoculated animals and showed narrower ranges from the onset of symptoms than the other strains. CbaAr-4005 was the most virulent for Swiss albino mice. Our results highlight the importance of performing biological characterisations of arbovirus strains likely to be responsible for emerging or reemerging human diseases.

In 1904 the Olympic and Anthropologic Games in Saint Louis, Missouri, were lost in the chaos of the Louisiana Purchase (Universal) Exposition. Although the expected universal spirit, for a long time Saint Louis expressed racial prejudices of its personal. This paper shows up how Sport Sciences and growing up Anthropology acted together in sense of serving questioned causes like racial ranking and colonization right. They were important in improving a feeling of nation in North American that took in grant sport as part of its constitution. The Universal Exposition and Market of Saint Louis offered new possibilities in definition of technological, racial, geographic and corporal borders.

Saint Louis encephalitis virus (SLE) is a mosquito borne disease. Only a small proportion of cases progress to severe clinical forms. There have been few reports on HIV-infected patients and the relationship between immunodeficiency and the course of the disease remains unclear. Herein we describe two cases of SLE in HIV-1-infected patients in Buenos Aires city.

Saint Louis encephalitis virus-infected cells were solubilized with Brij-58 nonionic detergent, and the clarified supernatant fluid was analyzed by diethyl-aminoethyl-cellulose chromatography. Three serologically distinguishable antigens were identified in viral protein peaks which eluted from diethylaminoethyl-cellulose at 0.05, 0.075, 0.125 and 0.2 m KCl. Antigen I was found in all column peaks, whereas antigen II was found only in the 0.05 m KCl eluate and antigen III was found only in the 0.2 m eluate. Immunodiffusion studies revealed that antigens I and II share at least one antigenic determinant and that antigen III is immunologically distinct from either antigen I or II. Polyacrylamide gel electrophoresis of 3H-leucine-labeled concentrated column peaks revealed that antigens I and II contain the major viral structural envelope and core proteins, respectively. Antigen III contains the largest virus-induced nonstructural polypeptide observed by polyacrylamide gel electrophoresis of 3H-leucine-labeled Saint Louis encephalitis virus-infected cells.

Saint Louis encephalitis virus, a member of the flaviviridae subgroup, is a culex mosquito-borne pathogen. Despite severe epidemic outbreaks on several occasions, not much progress has been made with regard to an epitope-based vaccine designed for Saint Louis encephalitis virus. The envelope proteins were collected from a protein database and analyzed with an in silico tool to identify the most immunogenic protein. The protein was then verified through several parameters to predict the T-cell and B-cell epitopes. Both T-cell and B-cell immunity were assessed to determine that the protein can induce humoral as well as cell-mediated immunity. The peptide sequence from 330–336 amino acids and the sequence REYCYEATL from the position 57 were found as the most potential B-cell and T-cell epitopes, respectively. Furthermore, as an RNA virus, one important thing was to establish the epitope as a conserved one; this was also done by in silico tools, showing 63.51% conservancy. The epitope was further tested for binding against the HLA molecule by computational docking techniques to verify the binding cleft epitope interaction. However, this is a preliminary study of designing an epitope-based peptide vaccine against Saint Louis encephalitis virus; the results awaits validation by in vitro and in vivo experiments.

The arboviruses are diseases that affect humans, horses and other animal species causing in the majority of cases an asymptomatic infection to neurological disorders. The Flaviviruses are important arbovirus found in Brazil. A descriptive study was conducted from serological surveys in 1775 horses for detection of anti-Flavivirus antibodies in the State of Paraná (Foz do Iguaçú, Maringá and Barracão), Santa Catarina (São Miguel do Oeste, Guaraciaba, Iraceminha, Dionisio Cerqueira, Guarujá do Sul and São José do Cedro) and Rio Grande do Sul (Uruguaiana, São Borja, Itaqui Alegrete and Porto Alegre) in the years of 2007 and 2008. By testing hemagglutination inhibition (HI) were detected HI antibodies of Saint Louis and Ilhéus and other Flaviviruses included in the tests, as well as cross-reactivity for Flaviviruses. By HI test, 14.3% (254/1775) of animals were positive for Flavivirus, monospecific reactions were observed in 42.9% (109/254) serum samples, being that 78.9% (86/109) for St. Louis, 17.4% (19/109) for Ilhéus and 3.7% (4 / 109) for Rocio and cross-reactions were detected in 57.1% (145/254). Among the positives, there was no difference between the sexes. The age group ≥ 10 years old was the most affected with 35.4% (73/206). The animals used for the practice of sport were positive in 34.3% (87/254). The state of Paraná showed 16.3% (107/657) of reacting animals...

The establishment of an Agribusiness Innovation Center (AIC) in Senegal takes advantage of already existing agriculture and agro-processing sectors and uses this to both identify and support a pipeline of growth enterprises that can be accelerated. The AIC initiative seeks to identify growth entrepreneurs and these are defined as entrepreneurs that can create a significant number of job opportunities while expanding markets through regional, national and export sales. Their impact is therefore much deeper than survivalist entrepreneurs who are in business to support their immediate family livelihood. Once identified, the AIC supports them to make best use of resources and market opportunities. In a phased approach, starting with the Saint Louis region, the AIC is introducing pre-incubation support that can, depending on the initial outcomes, develop into a future AIC hub being developed in each of the regions. The Saint Louis Satellite AIC (sAIC) includes the following activities: 1) establishment and awareness creation; 2) introductory entrepreneurship workshops; 3) pre-incubation enterprise development programme; 4) assessment of regional business opportunities in the region and market opportunity matching with local enterprises; and 5) initiation of incubation for selected enterprises.

Saint Louis encephalitis virus (SLEV) is a member of the Japanese-encephalitis virus serocomplex of the genus Flavivirus. SLEV is broadly distributed in the Americas and the Caribbean Islands, where it is usually transmitted by mosquitoes of the genus Culex and primarily to birds and mammalian-hosts. Humans are occasionally infected by the virus and are dead-end hosts. SLEV causes encephalitis in temperate regions, while in tropical regions of the Americas, several human cases and a wide biological diversity of SLEV-strains have been reported. The phylogenetic analysis of the envelope (E) protein genes indicated eight-genotypes of SLEV with geographic overlap. The present paper describes the genotyping of two SLEV viruses detected in mosquito-pools collected in northern Colombia (department of Cordoba). We used reverse transcription-polymerase chain reaction to amplify a fragment of theE-gene to confirm the virus identity and completeE-gene sequencing for phylogenetic analysis and genotyping of the two-SLEV viruses found circulating in Córdoba. This is the first report of SLEV genotype IV in Colombia (Córdoba) in mosquitoes from a region of human inhabitation, implicating the risk of human disease due to SLEV infection. Physicians should consider SLEV as a possible aetiology for undiagnosed febrile and neurologic syndromes among their patients who report exposure to mosquito-bites.

O vírus da dengue (DENV), frequentemente envolvido em epidemias de grande proporção, e o vírus da febre amarela (YFV), responsável por surtos silvestres esporádicos, são considerados os flavivírus circulantes mais importantes no Brasil. Por este motivo, o diagnóstico laboratorial de doença febril aguda indiferenciada durante períodos epidêmicos é frequentemente direcionado para dengue e febre amarela no país, dificultando a detecção de outros arbovírus possivelmente circulantes, incluindo o vírus da encefalite de Saint Louis (SLEV), que é amplamente disperso nas Américas. O objetivo deste estudo foi investigar molecularmente a presença de 11 flavivírus no soro de 604 pacientes durante grande epidemia de dengue no estado de Mato Grosso (MT), Centro-Oeste do Brasil, entre 2011- 2012. Concomitantemente, 3.433 fêmeas de Culex spp. capturadas com aspirador de Nasci na cidade de Cuiabá, MT e alocadas em 409 pools com 1-10 mosquitos em 2013 foram testadas por multiplex seminested RT-PCR para os mesmos flavivírus. O SLEV foi detectado em três pacientes co-infectados com o DENV-4 das cidades de Cuiabá e Várzea Grande, MT. Um dos pacientes apresentava tripla co-infecção com DENV-1. Nenhum paciente referiu histórico recente de viagem ou acesso a áreas rurais/silvestres. Um pool contendo uma fêmea de Culex quinquefasciatus foi positivo para o SLEV...

Durante el mes de marzo de 2013 una población de palomas torcazas (Zenaida auriculata) se instaló en una zona céntrica de la ciudad de Buenos Aires. Conociendo el rol que poseen estas aves como hospedadores competentes del virus de la encefalitis de Saint Louis (SLEV), fue colocada en el lugar una trampa de luz tipo CDC, a fin de realizar una vigilancia entomológica. Durante ese mes,fueron capturados 5 grupos de mosquitos (n = 48), 3 correspondieron a la especie Culex pipiens (n = 10) y 2 a Culex spp.(n = 38), no pudiéndose determinar en estos últimos con precisión la especie por encontrarse dañados. En un grupo de mosquitos Culex spp. se detectó el SLEV por técnicas moleculares. Posteriormente fue secuenciado y clasificado como perteneciente al genotipo III.
