The following quote from the translated abstract of the article Management Of COVID-19: The Zhejiang Experience Kaijin Xu et al., from the Journal Of Zhejiang University, mentioned:

Some patients with COVID-19 showed intestinal microbial dysbiosis with decreased probiotics such as Lactobacillus and Bifidobacterium, so nutritional and gastrointestinal function should be assessed for all patients. Nutritional support and application of prebiotics or probiotics were suggested to regulate the balance of intestinal microbiota and reduce the risk of secondary infection due to bacterial translocation.

As far as we could found, this text is the first report (published in the first half of May 2020) mentioning the influence of COVID19 on the gut microbiome composition. More information has been published in recent months about the links between this pandemic and the microbiome. This search included not only the respiratory microbiome but also those communities from the gut.

In this post, we present a list of remarkable papers covering connections between microbiome and COVID19. If you have more suggestions, please tell us in the comments.

Greetings from Wiltshire, England!

Today’s digest brings a little bit of everything. We’ve been cataloguing the latest COVID-19 publications during this pandemic, and today I’m please to bring you a paper combining both COVID-19 and microbiome research!

Elsewhere, there are plenty of environmental microbiome publications, including a great paper on the challenges of studying microbiology in space, an analysis of how aerosols spread COVID-19 and other infectious agents in dental practices, and plenty of articles on various aspects of soil microbiomes.

I hope everyone’s coping well during these times. On a personal level, I’m delighted to be returning to the lab this week to resume my PhD research into gut microbiomes and cancer. I’m glad to be back, but worried about how my pipetting skills have suffered during my time off!

Stay safe, and happy reading!

Happy Wednesday, y’all! Before we get to today’s papers, I wanted to let everyone know about a webinar happening on June 3rd at 12:00 PM E.T. called “Unraveling the link between the gut microbiome, human health, and disease.” Tomoya Yamashita, M.D., Ph.D. from Kobe University Graduate School of Medicine and Meredith Hullar, Ph.D. from the Fred Hutchinson Cancer Research Center will both be speaking. If you’re interested you can register here.

Now onto the highlights! We have some super interesting research to share with you today including an examination of the efficacy of transplanting the human gut microbiota into mice and its impact on studying immunological responses; evidence that early-life intestinal colonizers may influence brain development; and a new tool, pepFUNK, which uses a peptide-centric approach to identify KEGG pathways in metaproteomic datasets. Enjoy!

Hi everyone! This is my first contribution to the daily digest, and I’ll follow others’ lead by starting with the latest preprints concerning Covid-19. Away from the ongoing pandemic, some of the highlights include a look at how commensal gut microbes interact with pathogens, and an insight into deep sea oceanic crust microbiomes.

It seems to be a relatively quiet day today, so I’ve included an article from the University of Bristol which looks at how nanoscopic pillars on the surface of some insect wings protect them against bacteria. Perhaps only loosely a microbiome paper, but it’s worth a read for its electron microscopy alone!
