Feline Leukemia Virus
Feline leukemia virus (FeLV) is defined as a retrovirus that affects domestic cats, causing tumors, bone marrow disorders, and immunosuppression. It poses significant health risks due to potential reactivation in regressively infected cats, leading to virus shedding and clinical signs.
Bone marrow findings in cats with FeLV infection include evidence of neoplastic lymphoid, erythroid, or myeloid cells (which circulate in the peripheral blood of cats with leukemia ); myelodysplasia; hypoplasia or aplasia of erythroid, myeloid, or megakaryocyte cell lines; erythroid, myeloid, and megakaryocyte hyperplasia despite peripheral ...
