Canine and feline papillomaviruses: an update
Medeiros-Fonseca, B; Faustino-Rocha, Ana I; Medeiros, R; Oliveira, Paula A; Gil da Costa, RMPapillomaviruses are small viruses able to cause disease not only in mammalians, but also in birds and reptiles. In recent years, a rising number of papillomaviruses have been identified in dogs and cats, totaling 24 canine papillomavirus (CPV) and six feline papillomavirus (FcaPV). The canine and feline papillomaviruses (CPVs and FcaPVs, respectively) are responsible for multiple lesions in these domestic spec...

Medeiros, C; Silva, AR; Ferreira, T; Barros, L; Neuparth, MJ; Peixoto, F; Bastos, MMSM; Medeiros, R; Gil da Costa, RM; Pires, MJ; Faustino-Rocha, Ana Infections with certain types of papillomavirus, such as the human papillomavirus 16 (HPV16), are associated with the development of preneoplastic lesions and cancers of the anogenital, and head and neck regions. Cytinus hypocistis (L.) L. extracts are composed of substances presenting antiproliferative, antioxidant, anti-inflammatory and antibacterial properties, which might be promising as new therapeutic comp...
Assessing the in vivo effects of Pteridium aquilinum extract in K14-HPV16 trans...
Medeiros-Fonseca, B; Faustino-Rocha, Ana I; Pires, MJ; Queiroga, F; Medeiros, R; Gil da Costa, RM; Oliveira, PAPteridium aquilinum, commonly known as bracken fern, is a versatile plant species that thrive in diverse environmental conditions and has a global distribution. However, it possesses toxic properties that can lead to various diseases in animals. The consumption of bracken fern has been associated with the development of gastrointestinal and bladder tumours, thiamine deficiency, retinal degeneration, and haemorr...
