Human disease in Ribeira Valley, Brazil caused by Caraparu, a Group C arbovirus: report of a case by Lygia Busch Iversson( )

1 edition published in 1987 in English and held by 1 WorldCat member library worldwide

Relatam-se os dados clinicos e laboratoriais de um caso de molestia humana causada por virus identico ou antigenicamente muito relacionado ao arbovirus do Grupo C Caraparu, em um morador da regiao do Vale do Ribeira, Estado de Sao Paulo, sudeste do Brasil. O fato apresenta interesse medico sanitario pois embora existam evidencias da presenca de inumeros arbovirus na area, os unicos casos comprovados de doenca por esses agentes foram os de encefalite pelo virus Rocio durante a epidemia ocorrida em 1975-1977. Os resultados dos testes sorologicos sugerem diferenca anti-genica entre as cepas de virus Caraparu isoladas nos Estados de Sao Paulo e Para e proximidade antigenica entre a cepa de Caraparu de Sao Paulo e o virus Bruconha (AU)
Estado imune contra o vírus vacinal (17D) da febre amarela em duas populações do Estado da Bahia by Sandro Santos-Torres( )

1 edition published in 2000 in Portuguese and held by 1 WorldCat member library worldwide

A ocorrencia de casos de febre amarela (FA) e a ampla distribuicao do A. aegypti no Brasil, motivou o estudo da estimativa da protecao imune contra o virus amarilico vacinal (17D) em moradores de duas cidades do Estado da Bahia, Ipupiara (n = 461) e Prado (n = 228). Nesta area nao-endemica de FA, a pesquisa de anticorpos sericos contra o 17D (Acl7D) e contra 18 outros arbovirus, foi realizada pelo metodo da inibicao da hemaglutinacao (IH). Somente 1,2 por cento (8/689) dos individuos apresentaram Acl7D, sendo seis com resposta monotipica. A resposta sorologica do tipo heterotipica para Flavivirus (FLV) foi interpretada tambem como associada a resposta imune ao 17D, sendo mais frequente em Prado (30,3 por cento) do que em Ipupiara (23,2 por cento). A idade>/= 50 anos e moradia em outros Estados foram associadas com a soropositividade para FLV, do mesmo modo que a historia de vacinacao (17D). Mas, a historia de vacinacao apresentou baixos percentuais de sensibilidade (· 45,4 por cento) e de valor preditivo-positivo (/= 70,8 por cento) e do valorpreditivo-negativo (>/= 78,8 por cento). Em conclusao, foi baixa a frequencia (1,2 por cento) de moradores com Acl7D, apesar da frequencia maior (25,5 por cento) de portadores de anticorpos FLV, o que significa que 26,7 por cento da populacao estudada pode apresentar protecao contra o virus da FA (AU)

Arbovirus vector ecology in the Brazilian coastal range system by Delsio Natal( )

1 edition published in 1998 in English and held by 1 WorldCat member library worldwide

The general characteristics of the Coastal Range System and of the Atlantic Forest, situated on the eastern coast of Brazil, are described. The diversity of the Culicidae fauna which inhabit this geographical area is highlighted and special attention is given to the dominant species. Those species among which arboviruses have been identified and those which have tested for experimental transmission are set out. The species which by virtue of their characteristics present the necessary conditions to serve as vectors are selected. The discussion on the ecology and behavior of these species provides a panoramic view of the epidemiological importance of this ecosystem with regard to the arboviruses. Some comments on the lack of studies in this field are made(AU)

Rocio and vee virus activities in Brazil by Lygia Busch Iversson( )

1 edition published in 1994 in English and held by 1 WorldCat member library worldwide

In december 1975 a hitherto unknow Flavivirus was isolated from the cerebellum and upper spinal cord of a 39-years-old farmer in the region of Ribeira Valley, Sao Paulo, Brazil. The new virus, isolated and characterized by Lopes et al., was named Rocio (ROC), strain SP H34675. VEE virus is serologically grouped in the genus Alphavirus of family Togaviridae based upon cross-reactivity by hemagglutination inhibition (HI complement fixation (CF) and neutralization (N) tests (AU)

1 edition published in 1986 in Portuguese and held by 1 WorldCat member library worldwide

Foi realizado um estudo sorologico para verificacao da presenca de anticorpos para arbovirus em 288 individuos, residentes no povoado de Corte de Pedra, Valenca, Bahia. Foram observados anticorpos inibidores de hemaglutinacao e neutralizantes em 3.8% da amostra com a seguinte distribuicao para flavivirus: Ilheus (6), St. Louis (2), febre amarela (3), Rocio (1). Em um individuo, com residencia anterior na Regiao Norte foram detectados anticorpos para Mayaro. Em 75 individuos testados aleatoriamente nao foram observados anticorpos neutralizantes para o vesiculovirus Piry. Em outros 28 individuos, tambem selecionados ao acaso, anticorpos fixadores de complemento nao foram detectados para os virus dos grupos Changuinola, Phlebotomus e nao grupados BE AR 408005 e BE AR 421710. Chama-se a atencao para a necessidade de estudos complementares para esclarecer a transmissao do virus na area (AU)

The first laboratory confirmed cases of dengue fever in Brazil: virus isolation and sorological results by Amelia P. A Travassos da Rosa( )

1 edition published in 1998 in English and held by 1 WorldCat member library worldwide

Investigation of an extensive outbreak of febrile illness in the city of Boa Vista, Roraima State, Brazil, that began in late 1981 lasted until August 1982, established that dengue virus was incriminated in the etiology. Virological studies were made on 31 selected patients, dengue virus (types 1 and 4) was isolated in 12 of them. The virus (both types) was also isolated from three of 51 pools (1,478 mosquitoes) of Aedes aegypti captured especially downtown. To isolate the virus, all the material was inoculated in Aedes albopictus cells (C6/36) and in suckling mice, and virus isolates were identified by the indirect immunofluorescence using the monoclonal antibodies. The results of hemagglutination inhibition and complement fixation test with 27 paired acute convalescent phase sera and 359 single convalescent or contacts sera were highly suggestive of dengue etiology. The clinical features were those of classical dengue fever. Later, after the outbreak, serological survey involving 899 sera was conducted in order to determine the extent of the epidemic. The results indicated that at 11,000 dengue cases occurred. These are the first laboratory confirmed cases of dengue fever in Brazil(AU)

A recente outbreak of yellow fever in south of Maranhao State, Brazil: epidemiological, clinical and entomological findings by Pedro F. C Vasconcelos( )

1 edition published in 1998 in English and held by 1 WorldCat member library worldwide

An outbreak of Yellow fever virus (YF) ocorred in Maranhao State in 1993 (Barra do Corda, Esperantinopolisand Mirador) and 1994 (Pastos Bons), where several cases were reported. In 1993 a total of 932 people was examined for YF distributedas follows: 32 from Barra do Corda, 26 from Esperantinopolis and 874 from Mirador. From these, 70 cases were YF confirmed serologically (IgM capture MAC ELISA), histopathologically and/or by virus isolation. Another 4 cases diagnosed clinically and epidemiologically, brougth the total to 74 (Barra do Corda:5; Esperantinopolis:7 and Mirador: 62). The age of patients ranged from 2 to 71 years old (mean: 24):32 (43.2 percent) were female and 42 (56.8 percent) male and total lethality-rate was 17.5 percent (13/74). In Mirador (17,565 inhabitants), where an intesive survey was carried out, the incidence was 3,5 per 1,000 people, but in the rural YF risk area (14,695 inhabitants) the incidence was 4.2, and the mortality 16.1 percent (10/62). A total of 45.2 percent (28/62) asymptomatic infections were registered. In 1994, a total of 49 serum samples was obtained, 2 by virus isolation, 2 by seroconversion and 12 by serology. On the other hand, no fatal cases were reported in Pastos Bons. In 1993, 936 potential YF vectors were captured in Mirador and a single strain was isolated from a pool of Haemagogus janthinomys (infection rate (IR): 0.16 percent). In 1994, 16 strains were isolated from 1,318 Hg. janthinnomys (IR: 1.34 percent) and one Sabethes chloropterus (IR:1.67 percent). Our results suggest that this was the most extensive outbreak of YF in the last 20 years in Brazil(AU)

Relationship between the prevalence of antibodies to arbovirus and hepatitis B virus in the Vale do Ribeira region, Brazil by Cláudio Sérgio Pannuti( )

1 edition published in 1989 in English and held by 1 WorldCat member library worldwide

280 escolares de 6 a 14 anos de idade, residentes em Iguape, Vale do Ribeira, sudeste do estado de Sao Paulo, foram estudados com o objetivo de verificar possivel associacao entre a prevalencia de anticorpos para hepatite B e a exposicao a mosquitos hematofagos, avaliada indiretamente pela prevalencia de anticorpos de arbovirus. As criancas eram originarias de 4 areas com caracteristicas topograficas e fitograficas diferentes: 89 residiam em area urbana, 89 em area periurbana, 30 em area de cultivo extensivo de banana e hotalicas e 72 em area florestal. Estudos previos mostraram significante maior prevalencia de anticorpos de arbovirus nas areas cultivada e florestal do que nas areas urbana e periurbana. A pesquisa de anti-HBs foi feita por radioimunoensaio (Ausab, Laboratorio Abbott) e de anti-HBc por ensaio imunenzimatico (Rocha). Observou-se que os escolares residentes na area florestal apresentaram mais alta prevalencia (26/71 = 36.1%) de anticorpos para hepatite B de que os residentes nas areas urbana (5/89 = 5.6%), periurbana (6/89 = 6.7%) e cultivada (0.30 = 0%). Os resultados sugerem a existencia de fator comum na transmissao de arboviroses e de hepatite B, apoiado a hipotese que nas regioes tropicais com presenca de mata moaquitos possam desmpenhar importante papel na transmissao da hepatite B (AU)
Entomological studies on Dengue fever vectors in Brazil: the epidemics of Boa Vista, Roraima, 1982, Niteroi, Rio de Janeiro, 1986, and Ceara State, 1986, 1994 by Nicolas Degallier( )

No Brasil, o virus deo dengue e transmitido pelo mosquito urbano Aedes Aegypti. Foi na ocasiao dos primeiros isolamentos realizados a partir de casos humanos em Boa Vstas (RR) que o virus foi tambem isolado - sorotipos DEN 1 (1 amostra) e DEN 4 (2 amostras) - a partir de mosquitos naturalmente infectados. Durante o segundo episodio epidemico, em Niteroi (RJ), foram isoladas 3 amostras de DEN 1 a partir de mosquitosfemeas coletadas com isca humana ou em repouso. Durante essa epidemia, nos locais nao tratados por inseticidas, o indice de Breteau era de 102. A dissecacao de uma amostragen dos mosquitos mostrou que (1) as femeas agressivas eram mais velhas que as coletadas em repouso, (2) a proporcao de repastos interrompidos ou multiplos era elevada. Inqueritos entomologicos foram realizados durante as epidemias de 1986 e 1994 no Ceara. Tres amostras de DEN 1 e 16 amostras de DEN 2 foram isoladas a partir de AE. aegypti coletados em Cascavel e Caucaia, respectivamente. A suscetibilidade a infeccao oral dos mosquitos sobre os pacientes com viremia pelo virus DEN 2 foi testada. Positividade dos mosquitos apareceu a partir do terceiro dia apos repasto. 44 por cento dos mosquitos form infectados apos ter sido alimentados com sangue contendo um titulo de virus (Log TCD 50) igual a 3,5 . Tentativas de isolamento a partir de mosquitos machos, imaturos ou outras especies foram negativas(AU)
