Intracellular proteins of feline immunodeficiency virus and their antigenic relationship with equine infectious anaemia virus proteins

Feline 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...

Feline leukemia virus & feline immunodeficiency virus.

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...

Feline Immunodeficiency Virus Evolutionarily Acquires Two Proteins, Vif and Protease, Capable of Antagonizing Feline APOBEC3

The interplay between viral and host proteins has been well studied to elucidate virus-host interactions and their relevance to virulence. Mammalian genes encode apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like 3 (APOBEC3) proteins, which act as intrinsic restriction factors against lentiviruses. To overcome APOBEC3-mediated antiviral actions, lentiviruses have evolutionarily acq...

Genetic Analysis of Three Structural Proteins in Iranian Infectious Bronchitis Virus Isolate

Infectious bronchitis virus (IBV) is a contagious pathogen in fowl that results in economic loss in the poultry industry. In this study, the amino acids sequences of three structural proteins M, N, and S1 for five Iranian IBV isolated during 1998-2011 have been analyzed. Conserved and variable regions, hydrophobic characteristics and identity matrix were determined after alignment by Bioedit ve...
