Abstract
|
|
|
|
Three neonatal pigs from the same litter in a domestic farm were born with skin lesions. Grossly, multiple wellcircumscribed, round papules distributed over the skin of the three piglets. Two piglets were submitted for a diagnosis of skin disease. Microscopically, epidermal hyperplasia with ballooning degeneration of stratum spinosum keratinocytes was observed. Some keratinocytes contained eosinophilic intracytoplasmic inclusions and a central nuclear vacuole and chromatin margination. Swinepox (SWP) virus was detected by polymerase chain reaction and nucleotide sequencing, and Staphylococcus hyicus was isolated in skin lesions. Based on the gross findings and laboratory results, these piglets were diagnosed with congenital SWP with a secondary staphylococcal infection.
