Ninety-nine representative strains of Rhodococcus were compared through 129 unit characters and the data examined using the simple matching, Jaccard and pattern coefficients. Clustering was achieved using the unweighted pair group method with arithmetic averages algorithm. The numerical classification was not affected by the statistics used or by test error, estimated at 1.95%. Sixteen multimembered and 23 single member clusters were defined by the simple matching coefficient at or above the 89% similarity level. The numerical phenetic data support the taxonomic integrity of all 13 validly described species of Rhodococcus, including Rhodococcus aichiensis. Rapid enzymic tests based upon fluorophores 7-amino-4-methylcoumarin and 4-methylumbelliferone provide valuable data for rhodococcal systematics.
通过129个单位性状对99株红球菌代表性菌株进行了比较，并使用简单匹配系数、杰卡德系数和模式系数对数据进行了检验。采用算术平均的非加权配对组方法进行聚类分析。数值分类不受所用统计方法或测试误差的影响，估计测试误差为1.95%。在相似度水平为89%及以上时，简单匹配系数定义了16个多成员聚类和23个单成员聚类。数值分类数据支持所有13个有效描述的红球菌物种的分类完整性，包括爱知红球菌。基于荧光团7-氨基-4-甲基香豆素和4-甲基伞形酮的快速酶测试为红球菌系统学提供了有价值的数据。
