Riassunto

Microbiological Quality Assurance: A Guide Towards Relevance and Reproducibility of Inocula sheds light on the difficulties of obtaining results in the test tube that will be reproducible and relevant for a wide variety of tests. This book explores the current state of research in this area and troubleshoots the problems that may be encountered in setting up appropriate cultures. The text divides naturally into three sections-growth conditions, post-growth conditions, and applications. This book serves as a valuable resource for clinical microbiologists, pharmacologists, and anyone doing in vitro experiments.
