Figure 5From: Staphylococcus aureus intramammary challenge in non-lactating mammary glands stimulated to rapidly grow and develop with estradiol and progesteroneSomatic cells observed in collected mammary secretions. An eosinophil (E), lymphocyte (L), and macrophage (M) are depicted in A. B Depicts two neutrophils collected from a challenged quarter with the bottom neutrophil containing intracellular Staph. aureus (arrow). A binucleated macrophage is shown in C (arrow). These cells are suspected to originate from lumen resident macrophages that undergo incomplete cell division like the mitotic cell (arrow) shown in D. Scale bars = 10 µm.Back to article page
