Identification of Yersinia pestis by BBL Crystal Enteric/Nonfermenter Identification System

Abstract

The BBL Crystal Enteric/Nonfermenter System (Crystal) was used to test 25 archived isolates of Yersinia pestis to obtain a unique biochemical profile code for Y. pestis. The revised Crystal system and the API 20E system were compared by using 12 clinical human isolates of Y. pestis. Crystal correctly identified 11 of the 12 isolates, while API correctly identified 7 of the 12 isolates.
