International Journal of Systematic and Evolutionary Microbiology (IJSEM), formerly International Journal of Systematic Bacteriology (IJSB), is the official journal of record for novel prokaryotic taxa. Now in its 60th year (before 1966 it was known as the International Bulletin of Bacteriological Nomenclature and Taxonomy), the journal is the cornerstone of the dynamic field of microbial systematics. IJSEM publishes papers dealing with all phases of the systematics of prokaryotes, yeasts and yeast-like organisms, including taxonomy, nomenclature, identification, phylogeny, evolution, biodiversity, characterization and culture preservation. Its scope covers phylogenetic and evolutionary aspects of all micro-organisms.
