为评估奶山羊乳房炎灭活疫苗的免疫效果,以大肠埃希菌、金黄色葡萄球菌、凝固酶阴性表皮葡萄球菌及产色葡萄球菌为材料,经甲醛37℃灭活,按照6∶1(V/V)与铝胶盐充分混匀,分别经腹股沟皮下、颈部皮下注射途径,免疫泌乳期奶山羊,免疫剂量均为2 mL,共免疫2次,每次间隔14 d。分别在免疫前及第1次免疫后10、24、60、180 d 采集血样和乳样,ELISA 测定抗体效价,用快速诊断液检测隐性乳房炎,统计患病奶山羊的数量。结果显示,与对照组相比,两次免疫后血液及乳汁中针对大肠埃希菌、金黄色葡萄球菌、凝固酶阴性表皮葡萄球菌及产色葡萄球菌的抗体效价含量均显著增加(P <0.05),抗体维持时间长;颈部皮下免疫组免疫后180 d,腹股沟皮下免疫组免疫后的60 d,隐性乳房炎奶山羊数量均明显下降。结果表明,本研究制备的奶山羊乳房炎疫苗不仅能够刺激机体产生较好的体液免疫应答,而且还对隐性乳房炎有显著的治疗效果。
為評估奶山羊乳房炎滅活疫苗的免疫效果,以大腸埃希菌、金黃色葡萄毬菌、凝固酶陰性錶皮葡萄毬菌及產色葡萄毬菌為材料,經甲醛37℃滅活,按照6∶1(V/V)與鋁膠鹽充分混勻,分彆經腹股溝皮下、頸部皮下註射途徑,免疫泌乳期奶山羊,免疫劑量均為2 mL,共免疫2次,每次間隔14 d。分彆在免疫前及第1次免疫後10、24、60、180 d 採集血樣和乳樣,ELISA 測定抗體效價,用快速診斷液檢測隱性乳房炎,統計患病奶山羊的數量。結果顯示,與對照組相比,兩次免疫後血液及乳汁中針對大腸埃希菌、金黃色葡萄毬菌、凝固酶陰性錶皮葡萄毬菌及產色葡萄毬菌的抗體效價含量均顯著增加(P <0.05),抗體維持時間長;頸部皮下免疫組免疫後180 d,腹股溝皮下免疫組免疫後的60 d,隱性乳房炎奶山羊數量均明顯下降。結果錶明,本研究製備的奶山羊乳房炎疫苗不僅能夠刺激機體產生較好的體液免疫應答,而且還對隱性乳房炎有顯著的治療效果。

In order to evaluate the immune effect of the inactivated vaccine against mastitis in dairy goats, E.coli,Staphylococcus aureus ,coagulase negative Staphylococcus epidermidis and Staphylococcus chro-mogenes were inactivated by using methanal at 37℃ and then thoroughly mixed with adjuvant aluminum hydroxide with a ratio of 6:1 (V/V).Each lactating dairy goat was inoculated subcutaneously via neck or inguen twice with an interval of 14 d and the dosage was 2 ml each time.Blood and milk samples were col-lected before and post inoculation on day 10,24,60 and 180.The levels of antibodies were measured by an indirect ELISA while the numbers of goats suffering subclinical mastitis were measured by a rapid diagnos-tic reagent.The results showed that antibodies against E.coli,Staphylococcus aureus ,coagulase negative Staphylococcus epidermidis and Staphylococcus chromogenes in blood and milk were significantly increased compared with control after the twice inoculations (P < 0.05),and the antibodies could last long.The numbers of goats suffering subclinical mastitis of the neck and inguen inoculated groups were always less than control until the day 180 and 60 post inoculation respectively.In conclusion,the inactivated vaccine a-gainst mastitis developed in this study could not only stimulate the body to produce high-level antibodies but also has a significant therapeutic effect to subclinical mastitis.
