Isolation of Staphylococcus Hyicus from Seborrheic Dermatitis in a Pygmy Goat

Abstract

Microscopic examination of hematoxylin and eosin (HE)stained skin sections showed marked hyperkeratosis with parakeratosis of the epidermis. There also were numerous extensive foci of polymorphonuclear leukocytes aggregated in the hyperkerototic debris (Fig. 1). A few mononuclear inflammatory cells were sprinkled in the dermis but the major inflammatory changes were confined to the stratum comeum of the epidermis. No ectoparasites or mycotic organisms were detected in the skin sections. The renal corticomedullary junction vasculature showed infiltrates of leukocytes that were predominantly neutrophilic. There also were leukocytic casts and very few randomly scattered oxalate crystals in the medullary tubules. The liver showed mild centrilobular hepato
