The present study reports a case of malignant catarrhal fever (MCF), caused by the ovine hespesvirus type 2 (OvHV-2), in a cattle on a dairy farm in western Santa Catarina in 2023. The animal presented typical clinical signs of the MCF, and for diagnosis, histopathological examination, polymerase chain reaction (PCR) technique and DNA sequencing were performed. This study highlights the importance of keeping ovine and bovine herds separated in order to prevent the transmission of pathogens between these two animal species. Furthermore, this report reinforces the need for laboratory diagnosis to confirm clinical suspicions in order to obtain accurate diagnosis and effective prevention/control of infectious diseases affecting cattle.
