The common occurrence of multiple papillomavirus infections has been shown in several studies involving the human host. However, investigations with the aim of identifying mixed papillomavirus infections in cattle have been conducted only recently. In the current work we describe a co-infection with two different bovine papillomavirus (BPV) types that was identified in a bovine teat papilloma. The skin wart was obtained from a cow belonging to a Brazilian beef herd. A PCR assay was carried out with the FAP primer pair, which amplifies a partial segment of the L1 gene (approximately 478 bp), and the amplicon was submitted to direct sequencing. Because nucleotide sequences with satisfactory quality scores were not obtained, the amplicon was cloned and...

Cutaneous papillomatosis is a pathological condition commonly found in cattle and is characterized by the presence of benign proliferative tumors caused by bovine papillomavirus (BPV) infection. While multiple infections with human papillomavirus (HPV) are common in healthy and immunodeficient humans, studies with the aim of identifying mixed infections are still sporadic in veterinary medicine. The aim of this study is to describe the occurrence of multiple BPV infections in cattle affected by cutaneous papillomatosis. Fifteen skin warts were collected from at least two diverse anatomical regions of six bovines with papillomatosis belonging to three cattle herds from the Paraná state in Brazil. The BPV types present in the skin wart samples were...

Bovine herpesvirus 5 is a DNA virus that has been associated with meningoencephalitis in young cattle. While its clinical diagnosis is obscured by other major diseases that also produce similar neurological disease in cattle, the use of conventional virological techniques is hampered by the establishment of a lifelong latent infection in the host and the difficulty in differentiating BoHV-1 and BoHV-5. The aim of the current report is to describe the clinical and epidemiological aspects observed in a natural outbreak of BoHV-5 meningoencephalitis in a dairy cattle herd from Brazil. In the outbreak, the affected animals consisted of nine calves, which presented three possible forms of the neurological disease, subjectively classified as peracute, acute, and...

Bovine herpesvirus 5 detection by virus isolation in cell culture and multiplex-PCR in central nervous system from cattle with neurological disease in Brazilian herds

Bovine herpesvirus 5 (BoHV-5) is an important cause of meningoencephalitis in young and adult cattle. The multiple etiology of neurological disturbances in cattle makes the quick and conclusive diagnosis of BoHV-5 infection important for animal and public health, mainly because of herbivore rabies that is endemic in Brazilian cattle herds. The objective of this retrospective study was to use a multiplex-polymerase chain reaction (multiplex-PCR) for BoHV-5 and BoHV-1 glycoprotein C gene detection from stored central nervous system (CNS) tissue fragments of cattle with neurological clinical signs. Forty-seven frozen CNS samples of young and adult cattle from 31 herds in three Brazilian geographical regions (South, Southeast, and Center-west) were evaluated....
