SS 17: “Microbiomes and Social Equity” (19205)

Live discussion date: “Thursday, August 5th, 2021”

Live discussion time: 9:30 AM – 10:30 AM Pacific Time

Microbiomes — environmental, human and other organismal symbionts — are increasingly seen as critical physiological, developmental and ecological mediators within and among living things, and between the latter and our abiotic environments. Therefore, it is no surprise that microbial communities may be altered, depleted or disrupted by social and economic determinants. Social inequality entails concrete alterations and differentiation of microbial communities among social groups, by way of such factors as nutritional access, environmental pollutants or green space availability, often to the detriment of human and ecosystem health. This special session will be organized as a panel discussion with break-out groups in order to provide participants the opportunity to discuss the ways in which social inequity interacts with microbiomes, and how we might intervene as scientists and communities to promote favorable microbiomes while advancing social equality. We hope to generate research questions and actionable items.Panel speakers: Michael Friedman, Naupaka Zimmerman, Justin Stewart, Monica Trujillo, Sue Ishaq, Sierra Jech, Jennifer Bhatnagar, and Ariangela Kozik

Live discussion: Monday, August 2, 2021, 9:30 AM – 10:30 AM Pacific Time

Abstract:

Background/Question/Methods
The invasive European fire ant (Myrmica rubra) threatens native ant species and human health along the coast of Maine, United States. M. rubra mortality has been associated with infection by Pristionchus entomophagus, a necromenic nematode that is hypothesized to transfer pathogenic bacteria acquired from the environment to ant colonies. To investigate this hypothesis, we conducted a series of experiments on nematode-infected ants collected from Mount Desert Island. First, we isolated bacteria cultured from nematodes emerging from M. rubra cadavers and assessed the ability of the nematodes to acquire and transfer environmental bacteria to Galleria mellonella waxworm larvae. Second, we identified bacteria which were potentially transferred from nematodes to infected ant nests on MDI using bacterial community similarity and sequence tracking methods.

Results/Conclusions
Multiple bacterial species, including Paenibacillus spp., were found in the nematodes’ digestive tract. Serratia marcescens, Serratia nematodiphila, and Pseudomonas fluorescens were collected from the hemolymph of nematode-infected G. mellonella larvae. Variability was observed in insect virulence in relation to the site origin of the nematodes. In vitro assays confirmed uptake of red fluorescence protein (RFP)-labeled Pseudomonas aeruginosa strain PA14 by nematodes. Bacteria were highly concentrated in the digestive tract of adult nematodes, some bacteria were observed in the digestive tract of juveniles with a more significant amount on their cuticle, and none on the cuticle of adults. RFP-labeled P. aeruginosa were not observed in hemolymph of G. mellonella larvae, indicating an apparent lack of bacterial transfer from juvenile nematodes to the insects despite larval mortality.

Host species was the primary factor affecting bacterial community profiles. Spiroplasma sp. and Serratia marcescens sequences were shared across ants, nematodes, and nematode-exposed G. mellonella larvae. Alternative to the idea of transferring bacteria from environment to host, we considered whether nematode-exposure might disorder or depauperate the endobiotic community of an insect host. While total bacterial diversity was not statistically lower in nematode-exposed G. mellonella larvae when compared to controls, 16 bacterial sequence variants were less abundant in nematode-exposed larvae, while three were increased, including Serratia, Pseudomonas, and Proteus.
This study suggests that transfer of bacteria from nematodes to ants is feasible, although largely serendipitous, and may contribute to ant mortality in Maine. Hypothetically, the use of an engineered biological control, such as nematodes carrying specifically-seeded bacterial species, may be effective, especially if the pathogenic bacteria are naturally found in soil ecosystems and represent a low risk for biosafety control.

Abstract

Background, question, and methods

The American lobster, Homarus americanus, is a vital species for the fishing industry along the North Atlantic coast of North America. However, populations in Southern New England have declined, most likely due to increasing ocean temperatures and prevalence of emerging disease. Our previous work suggested that temperature may not be the sole cause for epizootic shell disease (ESD). Here, we examined the shell bacterial communities and progression of ESD in non-shell diseased and diseased adult female lobsters under three simulated seasonal temperature cycles for a year.

Fifty-seven female lobsters were wild-caught from Maine’s management zones F and G, and were assessed for shell disease progression on a scale of 0 (no observable signs) to 3 (visible disease on >50% of the shell surface). ESD-negative lobsters (apparently healthy) and ESD-positive (diseased) lobsters were randomly dispersed into 3 systems, and within each system, healthy and diseased lobsters were placed into separate tanks. These systems were maintained at three temperature ranges comparable to the average seasonal ocean temperatures for Southern New England (SNE), Southern Maine (SME), and Northern Maine (NME) regions. Samples were collected at three timepoints, a baseline “summer” temperature where all tanks were the same temperature, a winter temperature four months later, and a summer temperature 10 months after that.

A total of 131 experimental samples, plus 10 controls, passed PCR amplification, amplicon quantification and purification, Illumina MiSeq ver. 4 sequencing, and quality-control filtering.  Sequences were processed using the R software platform, using DADA2, phyloseq, vegan, and assorted other packages.

Results and conclusions

The bacterial richness on lobster shells at the baseline timepoint, when lobsters were wild-caught, was higher than the winter time point, 4 months later, or the summer time point, 10 months later, for the same lobsters after having been kept in tanks, regardless of their temperature or shell disease status.  Similarly, the bacterial community membership (unweighted Jaccard similarity) was similar for all samples at baseline, but diverged for later time points.

Tank temperature significantly affected microbial community membership (unweighted Jaccard similarity), as well as the abundance of those community members (weighted Bray-Curtis dissimilarity).

Contrary to our expectations, ESD shell disease index did not progress over time or in warmer conditions, and we hypothesized that frequent tank water changes and shell moltings may have reduced the microbial load. Preliminary results indicate that shell stage and shell disease index were positively associated with increased bacterial richness on lobster shells.

The first MSE symposium was a success!

Last week, the Microbes and Social Equity working group hosted its first ever symposium! We hosted 15 talks over 5 days, with each session melding presentations and active discussion groups.

In total, the symposium had 254 participants (467 registrants) from 22 countries, and including researchers from various fields and career levels, as well as members of the Maine State Legislation, and members of the general public.  The breakout rooms resulted in 16 draft documents collaboratively written by meeting ideas, which highlight issues/barriers to social equity in research and practice, resources and policy ideas to resolve inequity, research questions yet to be answered, and ideas for curricula development and integrating research and policy into education.

“Healthcare and the microbiome” at the Microbes and Social Equity virtual symposium, June 18, 2021

The Microbes and Social Equity working group and The University of Maine Institute of Medicine present an inaugural symposium on:

“Microbes, Social Equity, and Rural Health”

June 14 – 18th, 2021

Format: virtual meeting, Zoom platform.

Day 1 of the Microbes and Social Equity virtual symposium

Session 5: “Access to healthcare and the microbiome”

Friday, June 18th, 13:00 ~ 16:30 EST. Registration for this session is closed.

Section leader: Emily Wissel

Access to healthcare, including treatment and preventative care, is critical to moderate beneficial host-microbe interactions and mitigate host-pathogen interactions, yet healthcare is inequitably distributed and often curbed by social policy. For instance, maternity care is well-demonstrated to improve health outcomes and facilitate the transfer of beneficial maternal microbes to newborns. Policies which support breastfeeding likewise promote this transfer of maternal microbes. Similarly, newborns and infants with access to care in their first five years of life have better outcomes overall than those with limited access. This difference in care during early life can impact lifelong differences in outcomes, reinforcing inequalities present at birth. This session will cover topics from the vaginal microbiome during pregnancy to the infant gut microbiome after birth, with perspectives from a clinician, public health researchers, and a biological scientist.

Program and Registration

Registration, a full speaker list and program, and details of each day can be found here.

Registration will occur for each (day) section individually, so participants can select which topics to participate in, or all of them. 

Registration is free and open to the public.

Summary

Microorganisms are critical to many aspects of biological life, including human health.  The human body is a veritable universe for microorganisms: some pass through but once, some are frequent tourists, and some spend their entire existence in the confines of our body tissues.  The collective microbial community, our microbiome, can be impacted by the details of our lifestyle, including diet, hygiene, health status, and more, but many are driven by social, economic, medical, or political constraints that restrict available choices that may impact our health.   

Many human clinical conditions or diseases have been established as being related  to the state of the human microbiome.  It is known that collective social inequity can drive the prevalence, morbidity, and mortality of some of these diseases or conditions. When access to a nutritious  diet and healthcare are impeded by social inequity, these disparities can also affect the human microbiome; this can further contribute to reduced or poorly functioning microbiomes. 

Access to resources is the basis for creating and resolving social equity—access to healthcare, healthy foods, a suitable living environment, and to beneficial microorganisms, but also access to personal and occupational protection to avoid exposure to infectious disease. The emergence of the SARS-CoV2 (COVID-19) pandemic has dramatically altered our daily lives and the availability and ability to access essential resources, which has been worsened by pre-existing social inequity. Yet, the pandemic has also highlighted the inherent social disparity among those more likely to be exposed to infectious diseases.  

This meeting highlights recent investigations into beneficial and detrimental instances of microbial exposure, in the context of how social policy may mediate or deepen disparities between and within populations. In addition to invited presentations on thematic sections, each section will involve a discussion session using smaller breakout groups, to facilitate conversations and brainstorming between attendees.  These groups will be arranged around smaller themes or research questions, and group members will identify knowledge gaps for future research, as well as list actionable steps that can be taken using existing research to promote equitable social policy.  Ideally, meeting attendees will gain knowledge, collaborators and connections, and a path forward for turning their research into evidence-based policy to support public health.

Meeting dynamics

Unlike traditional symposium formats, this meeting will present some plenary-style talks by experts in the field, including biological scientists, social scientists, practitioners or policy makers, as well as facilitate discussion among participants. Each thematic section will feature 90 minutes of talks, which will be recorded and made publicly available after the live session.  After each plenary session, there will be 90 minutes of discussion in groups led by speakers and MSE group members, and assisted by notetakers, with ~10 participants per breakout room. Participants will be encouraged to “problem solve” a suggested topic or one of their own choosing.  The goal is to create action items that are meaningful for group participants, such as ideas for curricula development, identifying research needs or best practices, suggestions for engaging research in policy, and more.

“Stress and the microbiome” at the Microbes and Social Equity virtual symposium, June 17, 2021

Session 4: “Social and Environmental Stress”

Thursday, June 17th, 13:00 ~ 16:30 EST.   Registration for this session is closed.

Section leader: Patricia Wolf

While it has been established that human behavior may impact microbiome structure, it has become evident that this is only part of the story. Historically racist housing policies may lead to inequitable exposure of those living in segregated neighborhoods to environmental pollutants. Additionally, life-long exposure to social and environmental stress faced by minority groups within the US may increase risk to disease through the alteration of host and bacterial metabolites. These inequities were compounded during the COVID-19 pandemic, during which neighborhood structural environments led to differing access to healthcare and treatment for the disease. Notably, those with the least access often were subject to higher exposure to the disease due to having “essential” employment. This session will explore the social and environmental factors that can impact human microbiomes, and will discuss measures that investigators should incorporate into research in order to fully understand microbial mechanisms of disease.

Section leader: Gwynne Mhuireach

The relationship between health and greenspace is well-established. There is also a recognized association between social equity and distribution of greenspace in many cities—parks are often larger, higher quality, and more prevalent in higher-income, upper-class neighborhoods; private yards and gardens are a luxury sometimes inaccessible to lower-income households; even street trees tend to be older, larger, and more numerous in higher income neighborhoods. New evidence shows that exposure to microbial diversity may be an important ecosystem service provided by urban greenspace, as exposure to greater microbial diversity early in life is related to lower prevalence of autoimmune disorders, such as allergies and asthma. This session will explore how environmental justice can be used to resolve health, microbial, and land access disparities.

Tuesday, June 15th, 13:00 ~ 16:00 EST.  Registration for this session is closed.

Session leader: Laura Grieneisen

Access to fresh foods, and especially fruits, vegetables, and other products high in fiber, is well demonstrated to be affected by social inequity.  The lack of fiber and nutritious food can dramatically hamper a functional gut microbiome.  With the effects of COVID-19 being felt, the loss of income/loss of SNAP benefits and disruption to our food and transport systems will make it more difficult for many individuals to obtain a nutritious diet and reap the benefit of a healthy gut microbiome. This effect will be disproportionately felt by lower-income individuals. This session explores the effects of diet on the gut microbiome and health, food insecurity, policy to support food access, and how to use existing resources to create community-based food systems.

The human microbiota is a mediator between social determinants of health and health outcomes. Social determinants, such as racism, sexism and social class position are power relations that shape human microbial communities by providing access and exposure to varying biological factors. In turn, shifts in such communities are associated with distinct health outcomes.  This opening session will introduce the concept of microbes and social equity, and open the discussion on how to create change.

The emergence of the SARS-CoV2 (COVID-19) pandemic has dramatically altered our daily lives and the availability and ability to access essential resources, which has been worsened by pre-existing social inequity. Yet, the pandemic has also highlighted the inherent social disparity among those more likely to be exposed to infectious diseases.  

This meeting highlights recent investigations into beneficial and detrimental instances of microbial exposure, in the context of how social policy may mediate or deepen disparities between and within populations. In addition to invited presentations on thematic sections, each section will involve a discussion session using smaller breakout groups, to facilitate conversations and brainstorming between attendees.  These groups will be arranged around smaller themes or research questions, and group members will identify knowledge gaps for future research, as well as list actionable steps that can be taken using existing research to promote equitable social policy.  Ideally, meeting attendees will gain knowledge, collaborators and connections, and a path forward for turning their research into evidence-based policy to support public health.

Meeting dynamics

Unlike traditional symposium formats, this meeting will present some plenary-style talks by experts in the field, including biological scientists, social scientists, practitioners or policy makers, as well as facilitate discussion among participants. Each thematic section will feature 90 minutes of talks, which will be recorded and made publicly available after the live session.  After each plenary session, there will be 90 minutes of discussion in groups led by speakers and MSE group members, and assisted by notetakers, with ~10 participants per breakout room. Participants will be encouraged to “problem solve” a suggested topic or one of their own choosing.  The goal is to create action items that are meaningful for group participants, such as ideas for curricula development, identifying research needs or best practices, suggestions for engaging research in policy, and more.
