Última Seroprevalence of hepatitis B and C in Brazilian army conscripts in 2002: a cross-sectional study BJID Toledo Jr.,Antonio C.; Greco,Dirceu B.; Felga,Marcelo; Barreira,Dráurio; Gadelha,Maria de Fátima S.; Speranza,Francisco A.B.. Hepatitis B and C constitute important public health problems worldwide. In Brazil, studies on prevalence of viral hepatitis have local and regional characteristics; consequently it is difficult to define the national epidemiological situation. Our objective was to evaluate the seroprevalence of hepatitis B and C in conscripts of the Brazilian Army. A transversal study among males aged 17 to 22 years was conducted nationwide. After informed consent, each volunteer filled in a social-behavioral questionnaire and had blood drawn to test for HBsAg and anti-HCV. A total of 7,372 volunteers were evaluated in the second half of 2002. The prevalence of HBsAg was 2.6% (95% confidence interval: 2.2, 3.0) and that of anti-HCV was 1.5% (95% confidence interval: 1.2,...

Despite serological evidences of presence of hepatitis E virus (HEV) in humans or other animals, until this study the virus had not been detected and molecular characterization of the isolate that circulates in Brazil had not been described. Thus, we collected stool samples of young pigs and tested for presence of HEV RNA by RT-PCR, using primers for partial amplification of ORF2 sequence. Phylogenetic analysis with sequence obtained from the amplified products revealed that the HEV isolate identified here was most closely related to HEV isolates of genotype 3, which is commonly detected in HEV infected pigs. Nucleotide sequence analyses carried out with the entire amplified fragment, ORF2/ORF3 overlapping and ORF2 non-overlapping sequences showed highest...

Ano: 2007 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822007000400020 Viral Hepatitis C in a leading Brazilian hospital: epidemiological factors and genotyping BJM Bezerra,Cristianne S.; Lima,José M.C.; Vilar,Janaina L.; Moreira,José L.B.; Frota,Cristiane C.. The hepatitis C virus (HCV) is classified into six different genotypes and their distribution is different throughout the world. Epidemiologic studies are important to determine several characteristics of the virus, as well as the disease. This study analysed the prevalence of HCV and its genotypes among patients from a leading hospital in Ceará, which is located in Northeast Brazil. A total of 119 anti-HCV-seropositive patients, each having previously completed a questionnaire about risk behaviours related to HCV infection were tested for HCV infection using a qualitative HCV polymerase chain reaction (PCR) assay and genotyping by restriction fragment length polymorphism (RFLP). The detection was based on amplifying of the non-coding 5' region. Of the 119...
