Feline Leukemia And B Cell Lymphoma

Feline leukemia virus is a retrovirus that infects cats. FeLV can be transmitted from infected cats when the transfer of saliva or nasal secretions is involved.

Lymphoma is one of the most common cancers diagnosed in cats. It is a cancer of the lymphocytes (a type of white blood cell) and lymphoid tissues. Lymphoid tissue is normally present in many places in the body, including lymph nodes, spleen, liver, gastrointestinal tract, and bone marrow.

To date, only a few studies have examined the impacts of feline leukemia virus (FeLV) subgroups on disease development in spontaneously infected cats. The present study identified FeLV-A and FeLV-B subgroups in cats with lymphoma and leukemia and explored ... The present study identified FeLV-A and FeLV-B subgroups in cats with lymphoma and leukemia and explored the phylogenetic relationships of env sequences. Twenty-six cats with lymphoma (n=16) or leukemia (n=10) were selected. FeLV p27 antigen positivity was determined using ELISA, and proviral DNA in blood samples was detected using nested PCR. Feline lymphoma is a malignant cancer of the lymphatic system, the exquisitely structured arrangement of internal organs and tissues that directly or indirectly influences virtually every aspect of a cats physical existence. Unfortunately, says Margaret McEntee, DVM, professor of oncology at Cornell Universitys College of Veterinary Medicine, it is the most frequently diagnosed among all ... If the immune response does not eliminate the virus after initial exposure, FeLV spreads to the bone marrow and infects hematopoietic precursor cells.1 FeLV infection in the hematopoietic and lymphoid tissues can cause either cellular proliferation (resulting in lymphoma or leukemia) or myelosuppression.1 This can cause immune dysregulation and the increased susceptibility to opportunistic ... Male cats were overrepresented among renal lymphoma cases. Feline leukemia virus/feline immunodeficiency virus (FeLV/FIV) infection showed a strong correlation with mediastinal lymphoma. Overall, B-cell lymphomas were predominant; however, T-cell types were more frequently observed in European Shorthairs.
