upper respiratory tract diseases (urtd) are common clinical problem in cats worldwide. feline calicivirus (fcv) and feline herpesvirus type 1 (fhv-1) are the main primary pathogens. feline immunodeficiency virus (fiv) and feline leukemia virus (felv) are also among the most common infectious diseases of cats which suppress the immunity. oropharyngeal and conjunctival swabs and blood samples wer...

Currently, there is a debate among feline clinicians about the efficacy and safety of modified live virus vaccination in cats infected with retroviruses: immunodeficiency (FIV) leukemia (FeLV). In clinical routine, serological status all patients regard to retroviruses should be known, which ends up not occurring due financial reasons client or non-referral test by veterinarian. practice, it ob...

Purified feline leukemia virus, UV light-inactivated feline leukemia virus, and a synthetic peptide (CKS-17) homologous to a well-conserved region of the transmembrane components of several human and animal retroviruses were each studied for their effects on IgG production by feline peripheral blood lymphocytes. Using a reverse hemolytic plaque assay, both the viable virus and the UV-inactivate...

This study aimed to determine prevalences for anti-FCoV antibody, FeLV antigen, proviral DNA, and anti-FIV antibody among client-owned cats from the cities of Zagreb Varaždin in Croatia. Subjects included 106 tested at Faculty Veterinary Medicine, Vienna, Austria. Blood samples were with IFA FCoV titeres, ELISA p27 PCR RIM antibody. Prevalence was 41.51% 6.60%, respectively. A coinfection FeLV/...

Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are retroviruses with global impact on the health of domestic cats. The two viruses differ in their potential to cause disease. FeLV is more pathogenic, and was long considered to be responsible for more clinical syndromes than any other agent in cats. FeLV can cause tumors (mainly lymphoma), bone marrow suppression syndromes ...

The genomes of all animal species are colonized by endogenous retroviruses (ERVs). Although most ERVs have accumulated defects that render them incapable of replication, fully infectious ERVs have been identified in various mammals. In this study, we isolated a feline infectious ERV (RD-114) in a proportion of live attenuated vaccines for pets. Isolation of RD-114 was made in two independent la...

The feline kidney cell line CrFK is used extensively for viral infectivity assays and for study of the biology of various retroviruses and derived vectors. We demonstrate the production of an endogenous, RD114-like, infectious retrovirus from CrFK cells. This virus also is shown to efficiently package Moloney murine leukemia virus vectors.

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...
