Epithelial cells in mammary gland explants from mice assume a secretory appearance and synthesize the milk proteins, casein and alpha-lactalbumin, when cultured in the presence of insulin, hydrocortisone and prolactin. In cells from the glands of mature virgin animals such syntheses are known to require DNA synthesis. Addition of cytosine-beta-D-arabinofuranoside to the explant cultures suppres...
Several lines of evidence are presented for the involvement of spermidine in milk protein synthesis during hormone-dependent differentiation of mouse mammary epithelium in vitro. (a) When mammary explants from midpregnant mice are cultured in the presence of insulin, hydrocortisone, and prolactin, synthesis of casein and cr-lactalbumin increases markedly during the initial 48 hours. The require...
mastitis is one of the most important diseases of dairy cattle in the world. the identification and characterization of the constituent proteins in milk can be useful for studying the biochemistry and pathogenesis of mastitis. in this study, the electrophoretic patterns of milk from 10 healthy and 30 mastitic cows were studied. all of the latter milk samples were california mastitis test (cmt) ...
abstract: the growth rate of two probiotic strains with documented health effects was studied in ultra-high temperature treated milk separately and beside each other. the probiotic strains were lactobacillus acidophilus (la-5) and bifidobacterium lactis (bb-12). fermentation was followed for 12 h at 37 ˚c and the samples were analyzed for ph, titratable acidity and viable counts of probiotic ba...
The effectiveness of pasteurization and the concentration of Mycobacterium avium subsp. paratuberculosis in raw milk have been identified in quantitative risk analysis as the most critical factors influencing the potential presence of viable Mycobacterium paratuberculosis in dairy products. A quantitative assessment of the lethality of pasteurization was undertaken using an industrial pasteuriz...

Background: Intestinal colonization of the newborn is essential for establishment, maturation and maintenance of the gut mucosal barrier. The greatest difference between the microbiota of breast milk and Infant formula infants feeding is the numbers and species composition of Bifidobacteria. In this study, we tried to identify the native Bifidobacterium isolates obtained from the human’s breast...
UNLABELLED Human milk provides crucial nutrition and immunologic protection for infants. When a mother's own milk is unavailable, donated human milk, pasteurized to destroy bacteria and viruses, is a lifesaving replacement. Flash-heat pasteurization is a simple, low-cost, and commonly used method to make milk safe, but currently there is no system to monitor milk temperature, which challenges q...
Cheeses have been proposed as a good alternative to other fermented milk products for the delivery of probiotic bacteria to the consumer. The objective of this study was to assess the survival of two Lactobacillus salivarius strains (CECT5713 and PS2) isolated from human milk during production and storage of fresh cheese for 28 days at 4°C. The effect of such strains on the volatile compounds p...
