RESUMO
Teat papillomatosis is one important infectious disease affecting cattle health and results in significant economic losses especially in the dairy industry. Although there is a large number of commercial cattle herds in China, limited information is available for molecular epidemiological investigation of bovine papillomaviruses (BPVs). In October 2017, an outbreak of teat papillomatosis occurred in the Shandong Province of China. Samples were collected and diagnosed with PCR, and 3 full-length viral genomes were amplified from tissue samples collected from 3 outbreak farms. Analysis results revealed that the outbreak was associated with BPV type 10. This is the first report of BPV-10 infection in China and will contribute to the molecular epidemiological study of the disease.

To date, there have been no reports of coinfection with bovine papular stomatitis virus (BPSV) and bovine papillomavirus (BPV) in the same lesion. In the present study, one lingual papilloma-like sample was collected at an abattoir from the tongue of a 31-month-old Japanese black cow. Coinfection with BPSV and BPV was confirmed by histopathology, immunohistochemistry, PCR and RT-PCR. The evidence for coinfection with BPSV and BPV in the same lesion and an association of BPV with lingual papillomatosis will contribute to future epidemiological studies of these two viruses.
