Correlation Between Mastitis Pathogenic Bacteria and Glutathione Peroxidase Activity in Cows Milk

Abstract: Antioxidant activity of milk is due to the presence of antioxidant anzymes such as catalase, lactoperoxidase, glutathione-peroxidase, xanthin/oxidase, or vitamins and provitamins such as retinoils and carotenoids, tocopherols and ascorbic acid. The aim of this study was to establish a correlation between pathogenic bacteria type involved in cows mastitis and glutathione-peroxidase activity in milk. Determination of the enzyme activity was performed on milk samples, before and after germs inoculation with various dilutions o
