Human T-cell lymphotropic virus type I has been associated with adult T-cell leukemia and lymphoma, neurological disease (tropical spastic paraparesis or HTLV-I associated myelopathy) and, more recently, uveitis. This virus is highly endemic in some regions of the world, especially in southwest Japan, Caribbean islands, South America and parts of Central A frica1. The presence of HTLV-I/II in B...
The existence of extrahepatic replication sites of hepatitis C virus (HCV) remains controversial. Highly strand-specific Tth-based reverse transcriptase-polymerase chain reaction was used to search for the presence of viral RNA negative strand in lymph nodes from 16 patients with AIDS and in peripheral blood mononuclear cells (PBMC) from 14 other human immunodeficiency virus (HIV)-positive pati...
Using sera from hosts infected with bovine leukaemia virus (BLV), human T cell lymphoma virus types I and II (HTLV-I and -II), or simian T cell lymphoma virus type I (STLV-I), we found that the major gag proteins of these viruses cross-react immunologically. The specificity of this cross-reactivity was demonstrated by absorption using purified viral proteins, virus lysates and extracts of infec...
Background and Aims: Human T-lymphotropic virus (HTLV) is a human retrovirus which has been known to cause adult T-cell leukemia/lymphoma and some other inflammatory disorders. Patients with hereditary bleeding diseases are at high risk for these viruses. In this study, we evaluated serological HTLV-I/II infection among these patients in west Azerbaijan of Iran. Material and Methods: We stud...
Paraffin sections of retinal tissue from five patients who died from the acquired immune deficiency syndrome (AIDS) and retinopathy were examined by in situ hybridisation experiments with deoxyribonucleic acid (DNA) labelled with sulphur-35 of lentivirus, human T lymphotropic virus type III/lymphadenopathy associated virus (HTLV-III/LAV), and cytomegalovirus. HTLV-III/LAV ribonucleic acid (RNA)...
Hybrid selected translation was used to map the genome of herpesvirus saimiri, a lymphotropic and oncogenic herpesvirus. RNA extracted from virus-infected cells was hybridized to cloned genomic fragments, and the hybrid selected mRNAs were translated in vitro in a rabbit reticulocyte lysate. Forty-five virus-induced polypeptides were identified and correlated to their coding regions on the herp...
Twenty juvenile northern elephant seals (Mirounga angustirostris) that died between 1998 and 2004 had ulcers on the tongue, palatine mucosa, and/or tonsils. Histologic examination of the lesions revealed cytoplasmic swelling, nuclear pyknosis, and eosinophilic to amphophilic intranuclear inclusions bodies suggestive of herpesviral infection. Electron microscopic examination and polymerase chain...
Background: HTLV-1 (Human T_cell lymphotropic virus type), with about 20 million individuals infected worldwide, is a global health problem and is endemic in certain area such as Japan and Khorasan province of Iran. HTLV-1 is the causative agent of progressive diseases, Adult T cell Leukemia (ATL), and HTLV-I Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP) which have no ...
HTLV-1 (human T-lymphotropic virus type 1) and BLV (bovine leukemia virus) are two related retroviruses infecting CD4+ and B lymphocytes in humans and ruminants, respectively. During infection, the host-pathogen interplay is characterized by very dynamic kinetics resulting in equilibrium between the virus, which attempts to proliferate, and the immune response, which seeks to exert tight contro...
