“We Need to Translate Research Into Meaningful HTLV Health Policies and Programs”
OPINION article Front. Public Health, 10 May 2022Sec. Infectious Diseases – Surveillance, Prevention and Treatment https://doi.org/10.3389/fpubh.2022.883080
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 of High Risk HPV in HIV-Infected Women From Belém, Pará, Amazon Region of Brazil
Human papillomavirus (HPV) is the most common sexually transmitted infection in the world. Several studies have shown a higher prevalence of HPV infection in HIV-infected women. The aim of this study was to determine the prevalence and the genotype diversity of HPV infection in HIV-infected women. From April 2010 to December 2012 cervical specimens were collected from 169 HIV-infected women who screening for cervical cancer at Reference Unit in B…
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
Epidemiological aspects of retrovirus (HTLV) infection among Indian populations in the Amazon Region of Brazil
HTLV was initially described in association with a form of leukemia in Japan and a neurological disease in the Caribbean. It was soon shown that HTLV-II was endemic among Amerindians and particularly among Brazilian Indians. The Amazon Region of Brazil is presently the largest endemic area for this virus and has allowed several studies concerning virus biology, the search for overt disease, epidemiological data including detailed demographic data…
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…
O impacto da infecção por Chlamydia em populações indígenas da Amazônia brasileira
A disseminação das bactérias do gênero Chlamydia no Brasil, inclusive na região Amazônica, é pouco conhecida. Este estudo soroepidemiológico incluiu 2.086 amostras de soro de populações indígenas da Amazônia brasileira, empregando metodologia de triagem pela imunofluorescência indireta para pesquisa de anticorpos. Usou-se o sorotipo L2 da C. trachomatis como substrato; a seguir, para os quinze sorotipos de C. trachomatis e para a C. pneumoniae, d…
