Cats were vaccinated with fixed autologous feline immunodeficiency virus (FIV)-infected cells in order to present viral proteins to the immune system of individual cats in an MHC-matched fashion. Upon vaccination, a humoral response against Gag was induced. Furthermore, virus-neutralizing antibodies were detected in a Crandell feline kidney cell-based neutralization assay, but not in a neutrali...

The global incidence of pediatric HIV infection is estimated at 2.3 million children, most acquiring the infection from their mothers in utero, peripartum, or postpartum. Pediatric HIV infection typically causes a rapidly progressive disease when compared with adult infection, due in part to the profound susceptibility of the neonatal thymus to productive infection or degenerative changes. Fail...

Tumor necrosis factor alpha (TNF-alpha) induced morphologic changes such as chromatin condensation and cell shrinkage in a feline fibroblastic cell line (CRFK) chronically infected with feline immunodeficiency virus (FIV) but not in uninfected CRFK cells. DNA extracted from TNF-alpha-treated CRFK cells infected with FIV showed a ladder of nucleosomal DNA, indicating that this cytocidal effect b...

The natural occurrence of lentiviruses closely related to feline immunodeficiency virus (FIV) in nondomestic felid species is shown here to be worldwide. Cross-reactive antibodies to FIV were common in several free-ranging populations of large cats, including East African lions and cheetahs of the Serengeti ecosystem and in puma (also called cougar or mountain lion) populations throughout North...

Feline calicivirus (FCV) is a highly contagious pathogen of cats that can be grown in cultured cells. FCV is used as a model to study nonculturable caliciviruses, such as noroviruses. We determined the complete genome sequence of the FCV 2280 strain from the American Tissue Culture Collection.

the present study was carried out for the antigen detection of feline panleukopenia virus (fpv) in diarrhoeic cats referred to the veterinary clinic of the school of ahvaz university, in southwest iran. faecal samples were collected from 67 diarrhoeic household cats during 2005 to 2007. according to the age and clinical signs, the cats were divided into two groups; 6 months, hemorrhagic and ...
