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)

这项研究的目的是通过乳酸细菌（LAB）中乳腺的乳腺的细胞和免疫反应来表征奶牛中乳腺的细胞和免疫反应，并评估实验室IMI对乳腺炎的乳脂IMI的治疗作用。在输注后24-48小时注入的季度发现了SCC的显着增加。在牛中发现了免疫球蛋白，抗菌蛋白和细胞因子的mRNA表达的浓度显着增加。在治疗试验中，实验室到四分之一的IMI导致乳腺中明显的细胞和免疫反应。实验室的IMI可能具有控制乳腺炎的作用。（关键词：乳酸细菌，乳腺防御，免疫治疗试验，牛乳腺炎控制）
