Abstract

Clinical reference textbooks lack data for pyrrolidonyl arylamidase (PYR) activity in This study evaluated PYR activities of 21 strains by reference broth, rapid disc, and rapid slide methods. Species and subgroup identifications were confirmed by nucleic acid-based methods and included nine group A and 12 group B strains. Testing by rapid PYR methods with products from four manufacturers was performed at two testing locations, and, with the exception of one strain tested at one location using reagents from one manufacturer, each strain tested positive for PYR activity. Therefore, PYR may be a useful single-test adjunct for distinguishing from and other members of the group.
