his accessible reference of biochemical tests has been reborn to encompass the bacteriology revolution of the past two decades. This easy to use manual is divided into three sections: Individual Biochemical Tests , Multi-Test Systems and Identification Schemas . Individual Biochemical Tests offers 41 chapters, each devoted to a single biochemical test; nine new tests have been added since the last edition. The Multi-Test Systems section provides commercially prepared multi testing kits, media, and alternate procedures for bacterial identification, while section three is broken into three chapters providing identification schemata of medically important bacteria. New colour plates, new nomenclature, and identification tables and flow charts are included.
