摘要

Brazilian porcupinepox virus (BPoPV) was recently identified in free-ranging Brazilian porcupines (Coendou longicaudatus) in Brazil. In this study, we investigated the histopathological and ultrastructural features of BPoPV infection in four individuals and documented the occurrence of BPoPV in Goiás state, Brazil, where the virus had not been reported previously. Cutaneous lesions exhibited characteristic poxviral cytopathic changes. Histopathological analysis and transmission electron microscopy (TEM) revealed intralesional poxvirus-like particles, confirming both epithelial and systemic viral tropism. These findings contribute to the current understanding of BPoPV-associated disease and raise concerns regarding its potential impact on wild porcupine populations and conservation efforts.
