56株鲁氏菌与64株鲁氏菌脲酶活性比较。在含琼脂和不含琼脂的尿素培养基中，在28°C下培养7天，结果表明，在不含琼脂的尿素培养基上产生了特征和一致的结果。在流体介质中。绿藓引起pH值升高，导致酚红变化最大，而红藓则没有变化。证明了琼脂对尿素水解的抑制作用。在琼脂培养基上，48株菌株中有9株（18.8%）。48株红霉菌中有3株（6.2%）的结果可疑。使用纯培养物进行测试是很重要的。
A comparison of the urease activity of 56 strains ofT.rubrumand 64 strains ofT.mentagrophyteson Christensen's urea medium with and without agar incubated 7 days at 28 °C showed that characteristic and consistent results are produced on this medium without agar. In the fluid mediumT.mentagrophytescaused a rise in pH, resulting in a maximum change of the phenol red, andT.rubrumproduced no change. The depressing effect of agar on the hydrolysis of urea was demonstrated. On the agar medium 9 (18.8%) of 48 strains ofT.mentagrophytesand 3 (6.2%) of 48 strains ofT.rubrumproduced doubtful results. It is important that pure cultures be used for the test.
