Research Abstract |
The aim of this study was to characterize the cellular and immune responses of mammary gland by intramammary infusion (IMI) of Lactic acid bacteria (LAB) in cows, and to evaluate the therapeutic effects of IMI of LAB to lactating cows withmastitis. Marked increase of SCC were found in infused quarter at 24-48 hr post infusion. Significantly increased concentrations of immunoglobulins, anti-bacterial proteins and mRNA expression of cytokines on milk leukocytes were found in cows. In therapeutic trials, IMI of LAB to quarters leads to a marked cellular and immune responses in mammary gland. The IMI of LAB may have a possible rolefor control of mastitis.(key words:lactic acid bacteria, mammary gland defense, immune-therapeutic trial, bovine mastitis control)
