Feline Leukemia Virus (FeLV)
Feline leukemia virus , a retrovirus, is a common infection of cats. It is the cause of more cat deaths, directly or indirectly, than any other organism and is widespread in the cat population.

Diagnosis of FeLV infection The American Association of Feline Practitioners (AAFP) recommends screening all cats for FeLV infection at the time they are acquired, before initial vaccination, after potential exposure to FeLV-infected cats, and as part of a diagnostic workup for any illness.
Feline Leukemia Virus

Feline leukemia virus (FeLV), which is subclassified into three subgroups of A, B and C, is a pathogenic retrovirus in cats. FeLV-A is minimally pathogenic, FeLV-C can cause pure red cell aplasia, and FeLV-B is associated with a variety of pathogenic properties such as lymphoma, leukemia and anemia. FeLV-induced neoplasms are caused, at least in part , by somatically acquired insertional ...
Feline leukemia virus (FeLV) is one of the most common and important infectious diseases in cats, affecting between 2-3% of all cats in the United States and Canada. Infection rates are significantly higher (up to 30%) in cats that are ill or otherwise at high risk (see below). Fortunately, the prevalence of FeLV in cats has decreased significantly in the past 25 years since the development of ...

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.

Feline Leukemia Virus (FeLV)
Feline leukemia virus (FeLV) is one of the most important infectious diseases of cats worldwide. Affected cats can develop anemia (a low red blood cell level), cancers, and/or suppression of the immune system. The disease worsens over time and is usually fatal. The virus can infect domestic and wild cats (such as lions). Widespread testing and vaccination efforts have helped to reduce the ...
What is feline leukemia virus (FeLV)? Feline leukemia virus (FeLV) is a virus that infects cats. It was first identified in cats that had a form of leukemia (cancer of the white blood cells), but it is now known to cause a range of serious health problems. FeLV depresses the immune system, making infected cats more prone to infections, anemia, and certain cancers. Like all viruses, FeLV can ...

Feline leukaemia virus infection
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 (lymphosarcoma)' over 50 years ago by Jarrett et al. 3 FeLV infection can cause immunodeficiency, cytopenias and neoplasia in ...
