Experimental bovine immunodeficiency-like virus (BIV)-infection and mixed infection of BIV and bovine leukemia virus (BLV) were performed on sheep. BIV proviral DNA and anti-BIV antibodies were persistently detected in all BIV-inoculated sheep. A slight increase in lymphocyte counts was observed in BIV-infected sheep, but the percentages of CD4+ and CD8+ cells in sheep peripheral blood mononucl...

background: due to their similar routes of transmission, human immunodeficiency virus (hiv) and hepatitis b virus (hbv) co-infection occurs considerably. hbv infection progresses more rapidly in hiv-infected patients. therefore, hbv vaccination of all non-immune hiv infected patients is recommended. on the other hand, hiv-infected subjects have suboptimal responses to hbv vaccine. in this study...

Lentiviruses are a unique class of retroviruses that infect a subset of mammalian species, including humans. Human immunodeficiency virus type 1 and 2 (HIV-1 and HIV-2), simian immunodeficiency virus (SIV), feline immunodeficiency virus (FIV), bovine immunodeficiency virus (BIV), maedi-visna virus (MVV), and caprine arthritis encephalitis virus (CAEV) infections result in immunodeficiency syndr...

Background: Injecting drug users (IDUs) and prisoners are considered to be highly vulnerable to human immunodeficiency virus (HIV) infection in Iran. This study was carried out to determine the prevalence of HIV infection among IDUs released from jail in Bahar (Hamadan, Iran). Methods: In a cross-sectional study, 118 IDUs who were prisoners during 2001-07 were evaluated. Their demographic and p...

Heterosexual transmission of human immunodeficiency virus type 1 (HIV-1) is the major cause of the ongoing AIDS epidemic. Application of chemical barrier methods is expected to contribute to the worldwide control of this epidemic. Bovine beta-lactoglobulin modified by 3-hydroxyphthalic anhydride (3-hydroxyphthalovyl-beta-lactoglobulin [3HP-beta-LG]) was shown to inhibit HIV-1, HIV-2, simian imm...

Introduction Feline immunodeficiency virus (FIV) causes a slowly progressive multiorgan disease in infected cats and shows considerable pathogenic similarities to the human immunodeficiency virus type I (HIV-1i), the causative agent of AIDS (Miyazawa & Mikami, 1993; Pedersen et al., 1987; Yamamoto et al., 1988). It is therefore considered a useful small-animal model for HIV-l-induced AIDS studi...

the present study was performed to determine the prevalence of fiv in stray cat's population of ahvaz different area. serum samples were collected from 90 cats from 2005 to 2007. the studied cats were divided into two age groups (3 years) and based on clinical signs (such as lymphadenopathy, periodontal diseases, gingivitis, abscess and cashecsi) into two groups also. the results were analyzed ...

bovine immunodeficiency virus is a lentivirus which can cause varieties of infectious complications and induce remarkable losses to dairy industry. considering to the probability of worldwide distribution of the biv infection, this study was conducted for the first time in iran to determine of the status of biv infection in the holstein cattle and evaluate the associated findings. according to ...

Bovine immunodeficiency-like virus (BIV) is a bovine lentivirus that has antigenic and genetic homology with the human immunodeficiency virus. Little work has been reported on the effect of BIV infection on bovine immune function. This study was designed to evaluate lymphocyte blastogenesis, mononuclear cell subset numbers, neutrophil function, hematology, and clinical signs in three groups of ...
