2019 Microbiome Conferences

Looking for a microbiome conference or workshop? Here are some upcoming sessions we'll be following with interest. 2019 Microbiome Conferences: More Specific as Field Matures The Translational Microbiome Research Forum (TMRF) lists thirty-six 2019 conferences so far, and updates their Events page upon announcement of new meetings. While the majority (72%) of microbiome conferences in 2018 were of general interest, 2019 events are much more focused on...

Seasonal Cycling in the Gut Microbiome of the Hadza Hunter-gatherers of Tanzania

Researchers from Stanford University published a paper in Science titled "Seasonal cycling in the gut microbiome of the Hadza hunter-gatherers of Tanzania" which examines the relationship between diet, seasons, and the microbiome. The authors performed a longitudinal study on 350 stool samples collected throughout a year and a half and found that the microbial population in these samples changed in composition from wet to dry seasons as...

Webinar Q&A — Cyclical Bias

In a recent webinar, Dr. Alex Rodriguez-Palacios of Case Western Reserve University School of Medicine discussed a confounding influence on many common microbiome study endpoints uncovered in studies using the NesTiso system. The NesTiso system has been described in a previous publication1 and examined in an on-demand webinar. Due to time constraints, some of the questions you submitted to our Q&A session went unanswered. We present here...

Humanizing the gut microbiota of mice: Opportunities and challenges

On August 8, 2018, Randi Lundberg, DVM, PhD published a review paper titled, Humanizing the gut microbiota of mice: Opportunities and challenges in the journal, Laboratory Animals. The author acknowledges the need for in vivo models to study the human microbiome's interaction with a biologically relevant host. Mice are one of the most popular animal models used in biomedical research and have been adopted as one of...

Webinar Q&A — Nested Isolation

In a recent webinar, Dr. Alex Rodriguez-Palacios of Case Western Reserve University School of Medicine discussed the use of a new, low-cost caging system for conducting microbiome research in rodents. The speaker shared their experience with the NesTiso system and discussed: How NesTiso makes gnotobiotic research simple and practical How to inexpensively verify the germ-free status of your models How the portability of NesTiso systems accelerate gnotobiotic...

4 Gut-Brain Axis Publications You May Have Missed

You may have missed these publications in the recent rush of microbiome and germ-free research news, but researchers are making interesting connections between the gut microbiome and neurological functioning. Four studies examined relationships between the gut microbiome and mood, behavior, disease risk, and development. Prenatal Stress, the Microbiome, and Development Prenatal stress disrupts social behavior, cortical neurobiology and commensal microbes in adult male offspring. Scientists at Ohio...

New Research on Maintaining Complex Gut Microbiota in Mouse Models

Figure 1: Experimental design used to generate CD1 mice with four different gut microbiota (GM) profiles. Schematic diagram showing embryo transfer scheme used to rederive CD1 mice to C57BL/6J GMJAX, C67BL/6NTacGMTAC, Crl:CD1GMCRL, and HSD:ICRGMHSD surrogate dams. At maturity, offspring were mated using an outbred mating scheme within each GM profile and maintained as four separate breeding colonies for nine generations. An increased interest in studies involving the...
