Abstract EN
An approximately 5-month-old laboratory wether, originating from a local vendor with a closed flock and maintained on a preventative medicine plan, presented with a continuum of lesions from hemorrhagic papules, vesicles, and pustules, to multifocal necrotic scabs at the commissure of the lips, medial canthus of the left eye, and distal prepuce.
A presumptive diagnosis of Orf virus (ORFV) was made and the sheep was euthanized.
A full necropsy was performed, and histopathological evaluation of affected tissues revealed multifocal-to-coalescing necrotizing and proliferative cheilitis and dermatitis with eosinophilic intracytoplasmic inclusion bodies.
Electron microscopy findings revealed degenerate keratinocytes containing numerous typical 200–300 nm wide cytoplasmic parapoxvirus virions, confirming the diagnosis of ORFV.
We believe that this animal developed a clinical case of ORFV either due to an adverse reaction to an ORFV vaccine, or this animal had a case of preexisting ORFV which manifested after arrival at our facility.
