Scope
Aims, scope and focus
Microbiome Research Reports is published by OAE Publishing Inc. and is classed under Biology in the CAS Journal Ranking. By OpenAlex counts of its recent articles, its largest topics are Gut microbiota and health, Probiotics and Fermented Foods and Clostridium difficile and Clostridium perfringens research, together about 54.5% of its articles. (generated from OpenAlex topic counts and CAS ranking data)
The scope of the journal includes investigations of microbiomes present in one or various body compartments of human beings or other animals. Surveys on the establishment of microbial communities as well as on microbe-microbe interactions and microbe-host communication will be considered for publication. Specifically, emphasis will be placed on the identification and functional investigation of the role exerted by microbial taxa as well as microbial-genes and microbial metabolites markers associated with health and disease. MRR focuses on studies that not only provide compositional information pertaining to the microbiota/microbiome of various animal-associated niches, but also generate insights into molecular mechanisms underlying microbiome functionality. Thus, particular emphasis will be placed on functional interactions between microbes themselves, between microbes and their environment, and between microbes and their host. The overall aim of MRR is to publish high quality researches from scientists with a common interest in microbiome/microbiota research in all its multidisciplinary aspects. The main areas of interest include but not limit to the following: the structure, activities and communal behavior of microbial communitiesmicrobial community genetics and evolutionary processesmicrobial symbioses, microbial interactionsmicrobial metabolic and structural diversitymicrobial physiology, growth and survivalmicrobes and surfaces, adhesion and biofoulingmodelling, theory development and new analysis pipelinesviromes/phageomeantimicrobials and competition in microbiomesfungal communities (mycobiomes)exploration of microbial dark matterculturomics approaches applied to microbiomesmetabolomics and proteomic approaches applied to microbiomesmetatranscriptomics applied to microbiomesnew technological developments in the study of composition and activities of microbial communities, as-yet uncultured microorganismsgnotobiotic studiesdeveloment of minimal microbial consortia and synthetic communities for functional microbe-host studiesprobiotics, prebiotics, synbiotics and postbioticsmicrobial-derived metabolites originating from food/feed and playing a role on host physiologyeffect of microbiota modulation in gastrointestinal disorderseffect of microbiota modulation in metabolic disordersnovel treatments and clinical trialsimpact of dietary components on the microbiota, and inter-individual variation in responseshost-microbiome interaction in immune response
