This outstanding overview sets a new standard for a methods book on pathogen detection. The first chapter provides an outline of currently used routine methods, including their background, strengths and weaknesses, as well as comparing them to newer methods. The following chapters then cover novel methods already in wide use and which are still more experimental for routine purposes.
An invaluable resource for all medical laboratories and clinical institutions dealing with infectious diseases.
