HumanT cell leukemia virus (HTLV-1) is an oncoretrovirus that infects at least 10 million people worldwide. HTLV-1 exhibits a remarkable genetic stability, however, viral strains have been classified in several genotypes and subgroups, which often mirror the geographic origin of the viral strain. The Cosmopolitan genotype HTLV-1a, can be
Osretrovírus humanos constituem uma família heterogênea de agentes infecciosos que podem ser veiculados por transfusões (Figura 1).Na espécie humana, até o momento foi demonstrada a infecção por cinco espécies de retrovírus: pelo HIV tipos 1 e 2, HTLV-1 e 2 e pelo HFV (vírus esponjoso humano). 4 O HIV-1/2 e o HTLV-1/2 podem ser transmitidos
TestFrequency and Turnaround Time (TAT) HTLV-l/-ll screening is performed daily Monday to Friday. HTLV-I/-II confirmatory testing is performed every two weeks. Turnaround time is up to 5 business days for negative results, and up to 14 business days from receipt by PHO’s laboratory for positive results.
Inthe northern region of Brazil, the prevalence of HTLV-1/HTLV-2 infection varies from 0% in the state of Amazonas to 0.3% in the state of Pará . The prevalence of anti-CMV IgG antibodies in pregnant women is high in Brazil (97.0%) [ 14 ] and various regions of the world (91.3–99.5%) [ 15 , 16 ].

OHLTV (Human T-cell lymphotropic virus) pertence a família Retroviridae no gênero Deltaretrovirus. Os retrovírus são RNA vírus que usam uma enzima chamada transcriptase reversa para produzir DNA a partir de RNA. O HTLV afeta predominantemente os linfócitos T. Existem 4 tipos de HTLV, estando os HTLV-1 e HTLV-2 envolvidos em epidemia e
Há2 tipos de HIV, HIV-1 e HIV-2. O HIV-1 causa a maioria das infecções pelo HIV no mundo todo, mas o HIV-2 provoca a maioria dos casos em partes da África Ocidental. Em determinadas áreas da África Ocidental, ambos os microrganismos são prevalentes e podem coinfectar os pacientes. HIV-2 parece ser menos virulento do que o HIV-1.

Introduction Adult T-cell leukemia/lymphoma (ATLL) is a mature, peripheral T-cell neoplasm caused by human T-cell leukemia virus type 1 (HTLV-1). 1,2 The virus is primarily transmitted via breastfeeding, blood transfusion, sharing of needles, and sexual intercourse. HTLV-1 infects up to 10 million people worldwide and is most endemic in
INTRODUCTION HTLV-1 was the first retrovirus identified as an etiologic agent of human disease [1, 2].This virus produces several malignancies including Adult T Cell Leukemia-Lymphoma (ATLL) and Tropical Spastic Paraparesis/ HTLV Associated Myelopathy (TSP/HAM) [].HTLV-1 spreads through parenteral, sexual, and vertical
HTLV1 is endemic in South America, affecting 13 countries and prevailing in several ethnic groups.19, 20, 21 In Brazil, HTLV-1 is found in immigrants from endemic areas such as Africa and Japan, 8, 21, 22, 23 their descendants and in the descendants of Amerindians who have inhabited South America for thousands of years.24, 25, 26
Infectionswith HTLV-1 and -2 were detected in 12 and 6 indigenous individuals living in 27 Amazonian villages in Peru and were more common among participants living in villages distant from larger port cities and women with non-monogamous sexual partners. Infections with HTLV-1 and -2 were detected in 12 (1.9%) and 6 (0.9%) indigenous
Objective Being a Caribbean country, the Dominican Republic is considered endemic for HTLV-1. Viral screening in blood banks is recommended for this blood borne infection. The purpose of this work is to analyze the seroprevalence and trends of HTLV-1/2 in the Dominican Republic blood donors; it is focused on Santo Domingo, the capital of the
Ovírus linfotrópico T humano tipo 1 (HTLV-1) é um retrovírus de RNA de fita simples, envelopado, da família Retroviridae. Ele é o único patógeno humano da subfamília oncovírus, que, dentre outros, também inclui o vírus HTLV-2. Os vírus HTLV-1 e HTLV-2 existem como provírus, isto é, o genoma viral permanece incorporado ao DNA de
Rexisoforms. HTLV-1 expresses one isoform of Rex known as p21Rex, while HTLV-2 expresses several isoforms known as truncated Rex (tRex). HTLV-2 tRex is expressed from two different mRNAs and via different initiation codons resulting in four distinct isoforms between the sizes of 17 and 22 kDa [ 109 ].
