INTERNATIONAL JOURNAL OF SYSTEMATIC AND EVOLUTIONARY MICROBIOLOGY
8303
Scope/Description:
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.

Impact Factor
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. In other words, the impact factor of 2024 - 2025 is the average of the number of cited publications divided by the citable publications of a journal. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Normally, journals with higher impact factors are often deemed to have more influence than those with lower ones. However, the science community has also noted that review articles typically are more citable than research articles.Here you can check the journal performance trends based on last 20 years of data, also check the latest journal citation reports 2025. Also Check H-Index, SCImago journal rank and journal impact factor 2025.

Other Journal Impact Indicator
Any journal impact factor or scientometric indicator alone will not give you the full picture of a science journal. That’s why every year, scholars review current metrics to improve upon them and sometimes come up with new ones. There are also other factors to sider for example, H-Index, Self-Citation Ratio, SJR (SCImago Journal Rank Indicator) and SNIP (Source Normalized Impact per Paper). Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.
