14. Seroepidemiology of hepatitis B virus infection and high rate of response to hepatitis B virus Butang®vaccine in adolescents from low income families in Central Brazil
In order to evaluate the seroepidemiology and response to Butang® vaccine in adolescents from low income families in Central Brazil, blood samples of 664 adolescents were tested for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), and hepatitis B surface antibody (anti-HBs) markers, and multiple logistical regression analysis was c

15. Infecção por Toxoplasma gondii e Neospora caninum em cães e lobos-guará: soroepidemiologia e imunodiagnóstico / Infecção por Toxoplasma gondii e Neospora caninum em cães e lobos-guará: soroepidemiologia e imunodiagnóstico
Toxoplasma gondii and Neospora caninum are two closely related apicomplexan parasites, even though phylogenetic, ultrastructural, antigenic and biological differences have been already described. Seroepidemiological studies have demonstrated that T. gondii infection is often in domestic and sylvatic canids, whereas N. caninum infection is less common, but it

16. Soroepidemiologic study about hepatitis B vírus infection (HBV) and evaluation of Butang vaccine seroconversion in teenagers living in the suburbs of Goiânia, Goiás / Estudo soroepidemiológico da infecção pelo vírus da hepatite B(HBV) e avaliação da soroconversão à vacina butang em adolescentes da periferia da região metropolitana de Goiânia, Goiás
To evaluate the seroepidemiology profile of the hepatitis B virus infection, and the response to Butang vaccine in adolescents from a low-income region in the Metropolitan Area of Goiânia city Goiás 664 individuals with 12 to 19 years old were interviewed regarding socio-demographic and HBV risk factors After blood samples were collected and serum samples

17. Seroepidemiology of neosporosis in cattle and dogs of rural properties in Viçosa and Mercês, Minas Gerais / Soroepidemiologia da neosporose em bovinos e cães de propriedades rurais, municípios de Viçosa e Mercês, Minas Gerais
Durante os últimos dez anos o protozoário Neospora caninum tem sido descrito e associado como agente etiológico de abortamentos infecciosos em bovinos. Esta doença em cães também tem caráter abortivo, mas como os caninos são hospedeiros definitivos, possuem relevante importância no ciclo de vida deste parasita, funcionando como reservatório da doen

18. Frequencia de Strongyloides stercoralis no Chile : detecção da parasitose mediante metodos parasitologicos e soroepidemiologicos
From 2000 to 2003, human serum samples of 2390 individuals and 600 dog fecal samples recovered in 13 squares and public parks in Chile were studied to determine the seroepidemiology of the Strongyloides stercoralis infection and the role of dogs on the transmission of this parasitose. Human serum samples were as follows: a) 10 S. stercoralis infected patient

21. Seroepidemiology of Klebsiella bacteremic isolates and implications for vaccine development.
The frequencies of capsular serotypes among 703 Klebsiella strains isolated from the blood of hospitalized patients were determined. More than 90% of the isolates were typeable, with 69 of the 77 known serotypes being identified. Serotypes 2, 21, and 55, representing 8.9, 7.8, and 4.8% of all the isolates, respectively, were observed at a frequency significa

22. Evaluation of a finger-stick specimen collection method for seroepidemiology of antibody to hepatitis A virus.
A finger-stick swab method of collecting blood specimens was shown to compare favorably with the conventional venipuncture method in serological determinations of antibody to hepatitis A virus by radioimmunoassay.

23. Seroepidemiology of Human Group C Rotavirus in South Africa
Sera from three separate healthy population cohorts were used to determine the incidence of group C rotavirus infections in 1,356 South Africans. Using an enzyme-linked immunosorbent assay based on a recombinant group C rotavirus VP6 protein, the total percent positivity was found to be 34.4% (range, 33 to 38%), with almost half of the population infected af

24. Molecular Cloning, Expression, Self-Assembly, Antigenicity, and Seroepidemiology of a Genogroup II Norovirus Isolated in France
Virus-like particles of Dijon171/96 virus, a genogroup II norovirus, were expressed in a baculovirus system and were used for a seroepidemiological study of 1,078 age-stratified human sera collected in Dijon, France. The results showed a seroprevalence of 74.1%. Furthermore, we showed that murine antibodies generated against recombinant Dijon171/96 virus, an
