Cell Host & Microbe was launched in March 2007. The journal’s mission is to provide a forum for the exchange of ideas and concepts between scientists studying the microbe with those studying the host immune, cell biological, and molecular response upon colonization or infection by a microbe.

Cell Host & Microbe will publish novel findings related to microbes (which includes bacteria, fungi, parasites, and viruses) from molecular and cellular biology to translational studies with particular emphasis on the interface between the microbe and its host (vertebrate, invertebrate, or plant; unicellular or multicellular). The unifying theme is the integrated study of microbes (pathogenic, non-pathogenic, and commensal) in conjunction and communication with each other, their host, and the cellular environment they inhabit. Work published in Cell Host & Microbe is expected not only to be of exceptional significance within its field but also of interest to researchers outside the immediate area. In addition to primary research manuscripts, Cell Host & Microbe will publish expert analysis, commentary, and reviews on topics of current interest in the field.

Trends in Microbiology provides a multidisciplinary forum for the discussion of all aspects of microbiology: from cell biology and immunology to genetics and evolution, and ranges across virology, bacteriology, protozoology, and mycology.

Microbiology is, at present, one of the fastest-moving disciplines in Life Sciences, thanks also to technological developments of recent years. The relative ease and rapidity with which small genomes can be entirely sequenced is beginning to have a significant impact on all areas of prokaryote biology, from pathogens to extremophiles, and will fuel new developments, for example, in drugs, vaccines, and industrial enzyme research. Recent international developments are also responsible for a renewed interest in microbiology.

The focus is on molecular microbiology and virology and includes topics such as genomics, the gamut of plant and animal host-pathogen interactions, host immune responses, characterization and evolution of virulence determinants, cell cycle and differentiation, symbiosis in plant and animal associations, environmental microbiology, biodiversity and evolution, population dynamics, sex and mutagenesis, antibiotic resistance and production, drug and vaccine targets, as well as aspects of prion diseases and of fungal and protozoan biology.
