Feline immunodeficiency virus ORF-Ais required for virus particle formation and virus infectivity.
The orf-A (orf-2) gene of feline immunodeficiency virus (FIV) is a small open reading frame predicted to encode a 77-amino-acid protein that contains putative domains similar to those of the ungulate lentiviral Tat protein. Orf-A is reported to be critical for efficient viral replication in vitro and in vivo. A series of FIV-pPPR-derived proviruses with in-frame deletions and point mutations wi...
متن کاملFeline leukemia virus and feline immunodeficiency virus.
Ophthalmic manifestations of FeLV or FIV infection can occur in all ocular tissues and may be manifestations of direct viral effects or secondary to viral-related malignant transformation. Additionally, the manifestations of common feline ophthalmic pathogens may be more severe and poorly responsive to therapy because of the immunosuppressive effects of FeLV or FIV infection. Prompt diagnosis o...
متن کاملActive human immunodeficiency virus protease is required for viral infectivity.
Retroviral proteins are synthesized as polyprotein precursors that undergo proteolytic cleavages to yield the mature viral proteins. The role of the human immunodeficiency virus (HIV) protease in the viral replication cycle was examined by use of a site-directed mutation in the protease gene. The HIV protease gene product was expressed in Escherichia coli and observed to cleave HIV gag p55 to g...

RISK OF INFECTION/EXPOSURE The risk of infection is higher in younger animals and cats that are in contact with multiple cats (strays). Generally, Feline Leukemia Virus (FeLV) is spread by casual contact between cats although as they age, resistance to infection develops. Feline Immunodeficiency Virus (FIV) is spread more commonly through bite wounds or through sexual behaviour. Exposure occurs...
متن کاملInfections of feline leukemia virus and feline immunodeficiency virus.
Feline retrovirus infections have been extensively studied for more than 30 years as an animal model for the persistent infections and pathogenesis caused by retroviruses in general. Two retroviruses, feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV), have been recognized as causative agents of a variety of diseases including proliferative and degenerative diseases. Recent st...
