Rapid Method of Determining Coagulase Activity During Staphylococcal Bacteriophage Typing
Abstract
Rapid Method of Determining Coagulase Activity During Staphylococcal Bacteriophage Typing Anita K. Highsmith and Emmett B. Shotts 1 Veterinary Public Health Laboratory, Epidemiology Branch, Communicable Disease Center, U.S. Public Health Service, Atlanta, Georgia ABSTRACT The plate test, a modification of the slide test described by Cadness-Graves was developed for the rapid identification of coagulase-positive staphylococci in conjunction with bacteriophage typing. An evaluation of 1,145 cultures by three coagulase-determination methods, the slide, tube, and plate tests, indicates that the plate test is as accurate as the slide tests, and the plate test agrees 97.7% with the tube test.
