From: Physiological response of mammary glands to Escherichia coli infection: A conflict between glucose need for milk production and immune response

Figure 13

(A–C) Histological sections of udder tissues of glands infected with pathogenic Escherichia coli. Representative hematoxylin-eosin histological sections of control and infected glands of 10 cows challenged with different mammary pathogenic strains of E. coli. Note the level of alveolar cuboidal epithelial structure in full lactating glands in high yielding cows (A), and increased interlobular collagen rich fibrous stroma and fat in low yielding cows (B). In challenged glands, increased interlobular collagen rich areas with fibrous stroma and fat was observed, with mononuclear leucocytes among lobules and PMN within normal alveoli in two out of 10 glands (C). Images were captured using the MagnaFire Digital Camera controlled by NIS-Elements F3.0 software (https://www.microscope.healthcare.nikon.com/products/software).
