GUIDELINE for Feline Leukaemia Virus Infection
Early concerns about zoonotic potential were based on FeLV growth in human cell cultures, experimental induction of lymphoma in non- feline species, and epidemiological associations between FeLV-infected cats and human leukaemia.
Updates in the diagnosis and management of feline leukemia virus (FeLV) Not all feline leukemia virus (FeLV) infected cats are the same. There are different stages of infection, different outcomes, and different disease manifestations. Some infected cats will go on to live a nearly normal lifespan while others may die within months to a few years. If each FeLV-infected cat is different, how do ...
Feline Leukemia Virus Disease

Feline leukemia virus (FeLV) is one of the most common infectious causes of disease of cats globally. Infection with FeLV can cause a variety of clinical signs, impacting a cat's longevity and quality of life. Vaccination and identification of infected cats is important in preventing disease transmission.
Overview of Feline Leukemia Virus Infection. First Described: Scotland, 1964 (Jarrett et al.) 1 Cause: Feline leukemia virus (family Retroviridae, subfamily Orthoretrovirinae, genus Gammaretrovirus) Affected Hosts: Domestic and some wild Felidae Geographic Distribution: Worldwide Mode of Transmission: Prolonged close contact with salivary secretions; to a lesser extent biting, transplacental ...

Feline Leukemia Virus Infection

The feline sarcoma virus (FeSV) also is a recombination of the FeLV-A genome with tumor-associated cellular genes (proto-oncogenes) and likewise is generated de novo in a FeLV-A-infected cat. The endogenous counterparts of exogenous FeLV, termed enFeLVs, are integrated into the genome of domestic cats and closely related wild felids.
Progressive feline leukaemia virus (FeLV) infection dramatically shortens the lives of infected cats, causing acquired immunodeficiency, aplastic anaemia, lymphoma, leukaemia and other myeloproliferative diseases. The potential impact of regressive FeLV infection on the development of disease remains largely unknown, although there is evidence it contributes to lymphoma development. Despite a ...

Feline leukaemia virus - still an enigma Feline leukaemia virus (FeLV) is a well-known pathogen occurring worldwide in domestic and small wild cats.1,2 It is a gammaretrovirus that was first described as 'a virus -like particle associated with leukaemia (lym-phosarcoma)' over 50 years ago by Jarrett et al.3 FeLV infection can cause immunodeficiency, cytopenias and neoplasia in cats with ...
