13. Avaliação das subpopulações de linfócitos T CD4+, linfócitos T CD8+ e da razão CD4+/CD8+ em gatos com gengivite crônica e infectados naturalmente pelo vírus da imunodeficiência dos felinos (FIV) / Evaluation of CD4+ and CD8+ T-Lymphocytes count and CD4+:CD8+ ratio in cats with chronic gingivitis and naturally-infected with feline immunodeficiency virus (FIV)
Chronic and intractable gingivitis in FIV-infected cats is a relatively common clinical problem in veterinary practice. The role of FIV in the etiology of persistent stomatitis is still undetermined. Oral manifestations often found in HIV-infected people are frequently the first clinical sign of the infection and can be considered as an indicator of the prog

14. Reação em Cadeia de Polimerase (PCR) para detecção dos genes gag e pol do Vírus da Imunodeficiência Felina (FIV) / Reaction in Chain of Polymerase (PCR) for detention of the genes gag and pol of the Immunodeficiency Virus, Feline (FIV)
O presente estudo teve como objetivo principal padronizar a técnica de reação em cadeia de polimerase (PCR) para detecção do genoma proviral do vírus da imunodeficiência felina (FIV), um retrovirus associado com a síndrome da imunodeficiência adquirida (AIDS) dos felinos. Avaliamos amostras de sangue de 97 felinos domésticos provenientes da cidade

15. Dynamics of toxoplasmic infection in cats infected by Feline Immunodeficiency Virus / Dinâmica da infecção toxoplásmica em felinos infectados pelo Vírus da Imunodeficiência Felina
Para avaliar se a dinâmica da infecção toxoplásmica em gatos infectados pelo VIF é diferente daquela que ocorre em gatos não infectados por esse retrovírus, gatos adultos infectados pelo Vírus da Imunodeficiência Felina (VIF) clade B assintomáticos (n=7) (Grupo I: VIF+TOXO+), e gatos sem a infecção viral (n=7) (Grupo III: VIF-TOXO+) foram inocula

16. Development and evaluation of immunoassay for detection of antibodies to the feline T-lymphotropic lentivirus (feline immunodeficiency virus).
The feline T-cell lymphotropic lentivirus (feline immunodeficiency virus) is a recently described feline-specific retrovirus that can produce chronic immunodeficiency-like disorders in cats. A microdilution plate format enzyme-linked immunosorbent assay has been developed to detect the presence of antibody to the virus in feline serum or plasma. Temporal stu

17. Neutralization of feline immunodeficiency virus by polyclonal feline antibody: simultaneous involvement of hypervariable regions 4 and 5 of the surface glycoprotein.
Sites involved in antibody-mediated neutralization of feline immunodeficiency virus were mapped by reciprocal exchange of envelope fragments or amino acids between molecular clones of feline immunodeficiency virus with different susceptibilities to neutralization by a polyclonal cat serum. Combinations of mutations within HV-4 or within HV-4 and HV-5 changed

18. Expression of CXCR4 on Feline Peripheral Blood Mononuclear Cells: Effect of Feline Immunodeficiency Virus Infection
CXCR4 expression on feline peripheral blood mononuclear cells (PBMC) was analyzed. While monocytes and B lymphocytes expressed CXCR4, no CXCR4 was detected on T lymphocytes, in stark contrast to the expression pattern on T lymphocytes from humans. In spite of the important role that CXCR4 plays in infection with feline immunodeficiency virus, expression on P

19. Vaccination protects against in vivo-grown feline immunodeficiency virus even in the absence of detectable neutralizing antibodies.
So far, vaccination experiments against feline immunodeficiency virus have used in vitro-grown virus to challenge the vaccinated hosts. In this study, cats were vaccinated with fixed feline immunodeficiency virus-infected cells and challenged with plasma obtained from cats infected with the homologous virus diluted to contain 10 cat 50% infectious doses. As

20. Specific Interaction of Feline Immunodeficiency Virus Surface Glycoprotein with Human DC-SIGN
DC-SIGN, a specific C-type lectin expressed on dendritic cells, binds and transmits multiple strains of primate immunodeficiency viruses to susceptible cells. Here, we report that human DC-SIGN also captures feline immunodeficiency virus via high-affinity (1 nM), Ca2+-dependent, d-mannose-inhibited binding to the major envelope glycoprotein, gp95.

21. A monoclonal antibody which blocks infection with feline immunodeficiency virus identifies a possible non-CD4 receptor.
Monoclonal antibody vpg15 detects a 24-kDa cell surface protein on feline cells permissive for infection with feline immunodeficiency virus (FIV). The antibody blocks infection of FIV-susceptible cells, and expression of the vpg15 marker is decreased in FIV-infected cells in vitro. These results suggest that the antibody may recognize an FIV receptor distinc

22. Experimental Mucosal Infection with Molecularly Cloned Feline Immunodeficiency Viruses
Four of six specific pathogen-free cats were infected after intravaginal exposure to molecularly cloned lymphotropic but non-Crandell feline kidney (CRFK)-tropic feline immunodeficiency virus strain TM2 and its AP-1 deletion mutant. The sequences of the env V3-to-V5 region which defines the CRFK tropism were unchanged in the infected cats through the infecti

23. A trap, neuter, and release program for feral cats on Prince Edward Island
A new program to address the feral cat population on Prince Edward Island was undertaken during the spring and summer of 2001. Feral cats from specific geographic areas were trapped, sedated, and tested for feline leukemia virus and feline immunodeficiency virus. Healthy cats were neutered, dewormed, vaccinated, tattooed, and released to their area of origin

24. Bicyclams, Selective Antagonists of the Human Chemokine Receptor CXCR4, Potently Inhibit Feline Immunodeficiency Virus Replication
Bicyclams are low-molecular-weight anti-human immunodeficiency virus (HIV) agents that have been shown to act as potent and selective CXC chemokine receptor 4 (CXCR4) antagonists. Here, we demonstrate that bicyclams are potent inhibitors of feline immunodeficiency virus (FIV) replication when evaluated in Crandell feline kidney (CRFK) cells. With a series of
