Pathology in Practice: Necrotizing (gangrenous) mastitis in a Lleyn cross ewe caused by Staphylococcus aureus
An approximately 1-year-old Lleyn cross ewe was found dead in the lambing pens. The ewe had given birth to twin lambs, unassisted, 13 days previously. No other clinical history was available.
The ewe underwent necropsy examination at the Department of Veterinary Medicine, University of Cambridge, United Kingdom. For histological analysis, tissue samples from all major organs were fixed in 10% neutral buffered formalin solution. Standard protocols were followed in the preparation of histological sections.
