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).

Feline Leukemia Virus (FeLV) is a virus that impacts cats; can cause cancer and blood disorders; and can compromise the immune system, making them more susceptible to infections. FeLV only affects cats and does not pose any risk to other species. This virus is found worldwide and affects approximately 2-3% of cats in the United States. Prevention

2016年6月14日 · 猫白血病病毒（FeLV）分为3个型：FeLV-A、FeLV-B、FeLV-C。 A型为嗜亲性病毒，在所有感染猫中均可发现；B型为双嗜性病毒，可在大约一半感染猫中发现；C型为嗜异性病毒，只在1%的感染猫中检出。

2013年1月1日 · FeLV-C is not transmitted between cats, but arises de novo in viraemic animals. Following emergence in vivo, FeLV-C gives rise to pure red blood cell aplasia and an anaemia that may prove fatal within weeks.

Feline leukemia virus (FeLV) is a retrovirus that infects cats. FeLV can be transmitted from infected cats when the transfer of saliva or nasal secretions is involved. If not defeated by the animal's immune system, the virus weakens the cat's immune system, which can lead to diseases which can be lethal. Because FeLV is cat-to-cat contagious ...

Feline Leukemia Virus is one of the most common infectious diseases in cats, affecting 2-3% of all cats in the U.S. The virus can cause cancer, blood disorders, and immune deficiency, which makes cats more susceptible to other infections.

2020年2月11日 · 猫白血病病毒（Feline Leukaemia Virus，FeLV）是属于逆转录病毒科的致瘤性RNA病毒亚科。 该病毒的特点是基因组可以整合进入宿主的细胞基因组中，FeLV可以在许多组织中复制，包括骨髓、唾液腺和呼吸道上皮等。 FeLV的分型. FeLV主要分为FeLV-A、FeLV-B和FeLV-C三个亚型，只有FeLV-A才能在猫中水平传播。 其他的亚型如FeLV-B和FeLV-C是在感染了FeLV-A的猫的体内，经过FeLV的突变和与宿主基因组或是内源性FeLV的重组后形成，都不会 …

FeLV is an oncogenic mammalian type C retrovirus which causes neoplasia (lymphoma), myelosuppression (anaemia) and immunosuppression (of T cells). Three different strains are currently recognised: FeLV-B which formed through FeLV-A recombining with endogenous retroviral sequences in the feline genome.
