Twenty-two isolates of Bordetella bronchiseptica were studied to determine the effects of pH, incubation temperature and type of media on peak acid and alkaline phosphatase activity. The pH optimum for alkaline phosphatase activity was 9.0 for all of the isolates tested. The pH optimum for acid phosphatase activity was 5.8 for 67% of the isolates and 4.8 for 33%. All of the isolates showed peak phosphatase activity at 37 degrees C. No preference was shown in 35% of the isolates between the types of media tested; however, 40% preferred tryptose broth, 20% preferred nutrient broth and 5% preferred brain-heart infusion broth. No relationship was shown between phosphatase activity and the mouse lethality of the isolates.
对22株支气管败血波氏杆菌进行了研究,以确定pH值、培养温度和培养基类型对酸性和碱性磷酸酶活性峰值的影响。所测试的所有分离株碱性磷酸酶活性的最适pH值为9.0。67%的分离株酸性磷酸酶活性的最适pH值为5.8,33%的分离株为4.8。所有分离株在37℃时均显示磷酸酶活性峰值。35%的分离株在所测试的培养基类型之间没有表现出偏好;然而,40%的分离株更喜欢胰蛋白胨肉汤,20%的分离株更喜欢营养肉汤,5%的分离株更喜欢脑心浸液肉汤。分离株的磷酸酶活性与小鼠致死率之间没有关系。
