Domestic cat hepadnavirus detection in blood and tissue samples of cats with lymphoma.
Domestic cat hepadnavirus (DCH), a relative hepatitis B virus (HBV) in human, has been recently identified in cats; however, association of DCH infection with lymphoma in cats is not investigated. To determine the association between DCH infection and feline lymphoma, seven hundred and seventeen cats included 131 cats with lymphoma (68 blood and 63 tumor samples) and 586 (526 blood and 60 lymph node samples) cats without lymphoma. DCH DNA was investigated in blood and formalin-fixed paraffin-embedded (FFPE) tissues by quantitative polymerase chain reaction (qPCR). The FFPE lymphoma tissues were immunohistochemically subtyped, and the localization of DCH in lymphoma sections was investigated using in situ hybridization (ISH). Feline retroviral infection was investigated in the DCH-positive cases. DCH DNA was detected in 16.18% (11/68) (p = 0.002; odds ratio [OR], 5.15; 95% confidence interval [CI], 2.33-11.36) of blood and 9.52% (6/63) (p = 0.028; OR, 13.68; 95% CI, 0.75-248.36) of neoplastic samples obtained from lymphoma cats, whereas only 3.61% (19/526) of blood obtained from non-lymphoma cats was positive for DCH detection. Within the DCH-positive lymphoma, in 3/6 cats, feline leukemia virus was co-detected, and in 6/6 were B-cell lymphoma (p > 0.9; OR, 1.93; 95% CI, 0.09-37.89) and were multicentric form (p = 0.008; OR, 1.327; 95% CI, 0.06-31.18). DCH was found in the CD79-positive pleomorphic cells. Cats with lymphoma were more likely to be positive for DCH than cats without lymphoma, and infection associated with lymphoma development needs further investigations.
期刊介绍：
Veterinary Quarterly is an international open access journal which publishes high quality review articles and original research in the field of veterinary science and animal diseases. The journal publishes research on a range of different animal species and topics including: - Economically important species such as domesticated and non-domesticated farm animals, including avian and poultry diseases; - Companion animals (dogs, cats, horses, pocket pets and exotics); - Wildlife species; - Infectious diseases; - Diagnosis; - Treatment including pharmacology and vaccination
