Molecular Microbiology, the leading primary journal in the microbial sciences, publishes molecular studies of Bacteria, Archaea, eukaryotic microorganisms, and their viruses.Research papers should lead to a deeper understanding of the molecular principles underlying basic physiological processes or mechanisms. Appropriate topics include gene expression and regulation, pathogenicity and virulence, physiology and metabolism, synthesis of macromolecules (proteins, nucleic acids, lipids, polysaccharides, etc), cell biology and subcellular organization, membrane biogenesis and function, traffic and transport, cell-cell communication and signalling pathways, evolution and gene transfer. Articles focused on host responses (cellular or immunological) to pathogens or on microbial ecology should be directed to our sister journals Cellular Microbiology and Environmental Microbiology, respectively.

分子微生物學，在微生物科學的主要期刊，出版細菌，古生菌，真核微生物的分子研究，和他們的病毒。研究論文應該使人們對基本生理過程或機制的分子原理有更深入的了解。適宜的主題包括基因表達與調控、致病性與毒力、生理與代謝、大分子(蛋白質、核酸、脂類、多糖等)的合成、細胞生物學與亞細胞組織、膜生物發生與功能、交通與運輸、細胞與細胞的通訊與信號通路、進化與基因轉移。有關宿主對病原體的反應(細胞或免疫學)或微生物生態學的文章應分別發表在我們的姐妹期刊《細胞微生物學》和《環境微生物學》上。
