Figure 4From: Differences in virulence between the two more prevalent Staphylococcus aureus clonal complexes in rabbitries (CC121 and CC96) using an experimental model of mammary gland infectionMammary gland lesions immunohistochemically stained showing different locations of the marked cells. A Macrophages (RAM11+) are located peripherally to the necrotic area to form “palisades”, and to separate necrotic tissue from healthy tissue. Scale bar = 500 µm. B An encapsulated abscess surrounded by loose connective tissue reveals the presence of abundant T-lymphocytes (CD3+) entangled in the layers of loose connective tissue around the abscess. Scale bar = 50 μm. C Proliferation of B-lymphocytes (CD79αcy+) in the mammary interstitium arranged in lines and forming strands. Scale bar = 25 μm. D Peripheral area of suppurative mastitis with a lobular pattern in which many cells are plasma cells (IgG+). Scale bar = 25 μm.Back to article page
