FeLV is an oncogenic retrovirus which causes neoplasia ([[Lymphoma|lymphoma]]), myelosuppression ([[Regenerative and Non-Regenerative Anaemias|anaemia]]) and immunosuppression (of [[Lymphocytes#T cells|T cells]]). Three different strains are currently recognised:  

FeLV is an oncogenic mammalian type C retrovirus which causes neoplasia ([[Lymphoma|lymphoma]]), myelosuppression ([[Regenerative and Non-Regenerative Anaemias|anaemia]]) and immunosuppression (of [[Lymphocytes#T cells|T cells]]). Three different strains are currently recognised:  

*FeLV-A -natural strain

*FeLV-A -natural strain

*FeLV-B which formed through FeLV-A recombining with endogenous retroviral sequences in the feline genome.

*FeLV-B which formed through FeLV-A recombining with endogenous retroviral sequences in the feline genome.
