Multi-Epitope Protein as a Tool of Serological Diagnostic Development for HTLV-1 and HTLV-2 Infections
A multi-epitope protein expressed in a prokaryotic system, including epitopes of Env, Gag, and Tax proteins of both HTLV-1 and HTLV-2 was characterized for HTLV-1/2 serological screening. This tool can contribute to support the implementation of public policies to reduce HTLV-1/2 transmission in Brazil, the country with the highest absolute numbers of HTLV-1/2 infected individuals. The chimeric protein was tested in EIA using serum/plasma of HTLV…
Prevalence and risk behaviour for human immunodeficiency virus 1 infection in Marajó Island, Northern Brazil
Although the study indicates a low HIV-1 prevalence in Marajó Island, some factors may increase the risk for HIV-1 and these include early sexual initiation, unprotected sexual intercourse and the use of illicit drugs
Molecular Epidemiology of Human T-Lymphotropic Virus Type II Infection in Amerindian and Urban Populations of the Amazon Region of Brazil
Molecular characterization of human T-cell lymphotropic virus II (HTLV-II) isolates in North America and Europe has shown the existence of two principal subtypes of the virus, HTLV-IIa and HTLV-IIb. Subsequent studies on HTLV-II isolates from Brazil have suggested the existence of a unique variant phylogenetically related to HTLV-IIa but phenotypically similar to HTLV-IIb with respect to the transactivatory protein, Tax. This variant has been des…
Heterogeneity of Y chromosome markers among Brazilian Amerindians
The allele frequency distribution of DYS19 and DYS199 loci were analyzed in 59 Brazilian Amerindians from five tribes from the Amazon region (Zoé, Awá-Guajá, Urubú-Kaapór, Katuena, and Kayapó, Xikrin of Bacajá village). Three different alleles of the DYS19 microsatellite (182-bp, 186-bp, and 190-bp) were found at average frequencies of 0.08, 0.85, and 0.07, respectively. The DYS199-T allele was identified in 78% of the Amerindians studied (43/55)…
