Abstract
Group A streptococci and enterococci were identified by two L-pyrrolidonyl-beta-naphthylamide (PYR) hydrolysis tests. One uses Minitek PYR disks (BBL Microbiology Systems, Cockeysville, Md.); the other uses a swab impregnated with PYR reagent. Both tests and Strep-A-Chek (EY Laboratories, San Mateo, Calif.), a commercially available PYR test, were compared with conventional methods. The PYR methods correctly identified all strains of group A streptococci and enterococci tested.
摘要
通过两种L-吡咯烷酮-β-萘酰胺（PYR）水解试验对A群链球菌和肠球菌进行鉴定。一种使用Minitek PYR试纸（BBL微生物系统公司，马里兰州科基斯维尔）；另一种使用浸渍有PYR试剂的拭子。将这两种试验以及一种市售的PYR试验Strep-A-Chek（EY实验室，加利福尼亚州圣马特奥）与传统方法进行比较。PYR方法正确鉴定了所有检测的A群链球菌和肠球菌菌株。
