The API 20S system (Analytab Products) was evaluated as a means of identifying 209 isolates of Lancefield group D streptococci to the species level. Results were compared with those from a conventional tube biochemical identification system and from serological grouping. Use of the latest 20S computerized data base allowed species identification of 97% (203 of 209) of test isolates after a 4-h incubation period and 99% (208 of 209) of test isolates if supplemental overnight biochemical tests were used to clarify the identity of five Streptococcus bovis-variant isolates. The API 20S system appears to be a convenient and accurate method for rapid, same-day species identification of group D streptococci.
对API 20S系统（Analytab产品公司）进行了评估，以确定其作为将209株兰斯菲尔德D组链球菌鉴定到种水平的一种手段。将结果与传统试管生化鉴定系统和血清学分型的结果进行了比较。使用最新的20S计算机数据库，在4小时孵育期后，97%（209株中的203株）的测试菌株可鉴定到种，若使用补充过夜生化试验来明确5株牛链球菌变异株的身份，则99%（209株中的208株）的测试菌株可鉴定到种。API 20S系统似乎是一种方便、准确的方法，可用于快速同日鉴定D组链球菌的种。
