Investigation of human papillomaviruses (HPV), mouse mammary tumour virus (MMTV), Epstein–Barr virus (EBV), and human polyomavirus entities in canine mammary tumours

Abstract

Abstract Introduction: The aim of the study was to investigate the presence of human papillomaviruses (HPV), mouse mammary tumour virus (MMTV), Epstein-Barr virus (EBV), and human polyomavirus BK in canine mammary tumours (CMTs) and to correlate the results of histopathological classification with the results of virological examination. Material and Methods: Eighty CMTs and ten normal canine mammary gland samples were evaluated using histopathological methods and TaqMan real-time PCR analysis. Results: The results indicated that all mammary tumours and normal mammary tissue samples were negative for HPV16 and other HPV, EBV, human polyomavirus, and human mammary tumour virus strains. Conclusion: Further studies should be performed to investigate the existence of other strains of HPV, EBV, and human polyomavirus in CMTs.
