This book is the new Greek edition of one of the world's leading introductory microbiology textbooks, the science that studies the world of microorganisms and is a fundamental pillar of modern biology.

Brock's Microbiology has been an invaluable resource internationally for successive generations of undergraduate and graduate students, as well as scientists in the life sciences. A fundamental focus of the book is understanding the basic biology of microorganisms, that is, the essential molecular mechanisms that govern their structure, function, and their integration into the environment.

It also presents some applications of fundamental social and economic importance in medicine, industry, agriculture, and biotechnology, applications that have their roots in the basic study of microorganisms.

Finally, the pages of the book feature several of the remarkable scientific developments of recent years, such as the substantial understanding of microbial life at a chemical level, genomic analysis, a better understanding of the evolutionary relationship among organisms, and the tripartition into Bacteria, Archaea, and Eukarya, modern virology, the impressive possibilities opened by the exploitation of microorganisms at a biotechnological level, and the revolution brought about by the study of microbiomes in understanding the integral role of microorganisms in human biology.
