The great diversity of microbial life is the remaining major reservoir of unknown biological diversity on earth. To understand this vast, but largely unperceived diversity with its untapped genetic, enzymatic and industrial potential, microbial systematics is undergoing a revolutionary change in its approach to describe novel taxa based on genomic/envirogenomic information. The characterization of an organism is no longer bounded by methodological barriers, and it is now possible to fully sequence the whole genome of a strain to study individual genes, or to examine the genetic information by using different techniques. In fact, application of genomics is helping not only to provide a better understanding of the boundaries of genera and higher levels of classification, but also to refine our definition of the species concept. In addition, increased understanding of phylogeny is allowing to predict the genetic potential of microorganisms for biotechnological applications and adaptation to environmental changes. The present Research Topic on “Microbial Taxonomy, Phylogeny and Biodiversity” compiles a collection of papers covering the use of genomic sequence data in microbial taxonomy and systematics, including evolutionary relatedness of microorganisms; application of comparative genomics in systematic studies; or metagenomic approaches for biodiversity studies. We hope that this eBook incentives and encourages researchers for future discussions on microbial taxonomy and phylogenetics.

The 6th edition of this popular textbook covers the key areas of bacteriology, including morphology, multiplication, metabolism, genetics, bacteriophages, classification and the basic practical procedures used by bacteriologists.

AIDS is undeniably one of the most pressing medical emergencies of our era but it is now 12 years since the discovery of HIV and, in spite of a world-wide research effort, we are still a long way from understanding and controlling AIDS. HIV 2 explores the biochemistry and molecular biology of HIV. Together with HIV 1, which describes studies of the virus and infected cells, it provides clear, practical instructions about how to study HIV in the laboratory.
