Izabella Sall studies microbiota in opioid use, points out that prolonged opioid use causes gut microbiota dysbiosis. Butyrate important in opioid tolerance, detected via several methods. See the preprint here: www.biorxiv.org/content/10.1...

#BeneficialMicrobes
Gut dysbiosis was inevitable, but tolerance was not: temporal responses of the murine microbiota that maintain its capacity for butyrate production correlate with sustained antinociception to chronic ...

Angela Poole studies dietary fiber intake. Recommended dietary intake is MUCH higher than we typically take in. Did a study during the pandemic ( #overlyhonestmethods shared) with high fiber diets, described in this paper: www.tandfonline.com/doi/full/10....

Gut microbial features and dietary fiber intake predict gut microbiota response to resistant starch supplementation
Resistant starch (RS) consumption can have beneficial effects on metabolic health, but the response, in terms of effects on the gut microbiota and host physiology, varies between individuals. Facto...

Daniel Y. Kim walks us through the potential mechanism of how 502A inhibits growth of MRSA in the nasal environment. I recognize him from a previous meeting and can't place which lab he was in. #BeneficialMicrobes

Shruthi Magesh from the Handlesman lab (which I inferred when I saw Handlesman taking a photo of her student, such a great #ProudPI moment) tells us a fascinating story about multi-species biofilms. Love the name of the communities, zorbs, from: www.nature.com/articles/s41...

Bacterial biofilms are aggregates of surface-associated cells embedded in an extracellular polysaccharide (EPS) matrix. Here, the authors describe a unique mode of collective movement by self-propelle...

Marienela Heredia is in the lab of my PI from grad school, Laura Knoll. Heredia studies Entamoeba and Tritrichomonas, which are often thought of as parasites, but have capacity to be symbionts. Love a good parasite/protist story. It's unpublished, looking forward to reading this

Lauren Lucas: bile acids are turned into 100s or 1000s of smaller primary and secondary molecules by microbiota, which play huge role in host health. Lucas is first author on most cited article in mSystems in 2021 (did I hear that right??)

Laura Fricke in Lindsey lab characterizes the contribution of Wolbachia to embryogenesis in parasitic wasps. I've never thought about microbe contribution to asexual reproduction, will now bug my genetics colleague to look at this in their bug.

Andrea Boyd in the Lemon lab has developed a new system to study how nasal microbiome members interact with host cells and it is very cool. Definitely keep an eye out for that publication.

Sergio López-Madrigal also studies Wolbachia and is characterizing microbe-host interactions. This work is unpublished as well, but I took notes for a mentee about a potential assay to use in our system.

Mische Holland was sequencing genomes of amoeba and accidentally identified endosymbionts! I was going to go into much greater detail because I thought it was published, then doubled checked the paper I found and it isn't published. #BeneficialMicrobes

Kayla Cross from Zakee Sabree's lab studies the microbiome metabolic function in cockroaches given different diets. Turns out redundancies are important in maintaining the function of the microbiome, and that just looking at taxa doesn't give the full picture of the microbiome.

Katherine Xue (starting own lab in 2025 at UC Irvine and looking for mentees) asked whether antibiotic disruption leads to increased colonization with new microbes. Found that subset of subjects saw new colonization, but only after delay.

Alecia Septer studies the role of Type 6 secretion systems in colonization of Vibrio in squid. Most assume that the energy cost of a gene and system drives whether a gene is retained in a symbiont. Septer tested this and found it's more complicated than simple loss/retention.

Luella Allen-Walker in the Barott lab asked how corals respond to heat stress, with a focus on acid/base regulation of the host and symbionts. I really liked this view and interdisciplinary focus of this project. #BenficialMIcrobes

Mark Heggen in the Van Pijkeren Lab tells us an unpublished story about how the small molecule (p)ppGpp contributes to resistance of microbiota members against antimicrobials. He had an interesting screen that he used to identified genes of interest that I need to ask about. #BeneficialMicrobes
