In his book on pharmaceutical microbiology, Michael Rieth, a PhD microbiologist with many years of experience in microbiological quality testing in the pharmaceutical industry, addresses all aspects of this essential field for pharmaceutical production. Key topics include quality control methods, environmental monitoring in pharmaceutical and chemical production, as well as operational hygiene. The focus is on bacteriological procedures, including microbiological rapid methods; however, cell culture methods and animal models are also discussed. For the second edition, new topics such as "Low Endotoxin Recovery" and the masking/demasking of endotoxins have been included. Whenever possible, references to the latest editions of European and US pharmacopoeias are made.
