"Antibiotic Resistance in Louisiana"

fdabramo

I situate my research at the crossroads of history, philosophy, sociology and anthropology of science. In the past, I have focused on epigenetics, environmental research, empirical bioethics and environmental justice, within and outside the academia, as you can read here, or here. Now I am focusing on antibiotic resistance, and I use it as a lens to interpret the contradictions of the last century derived by industrial production, environmental degradation and biomedical cultures.

What interests me is the (at that time) new epistemic discourse that since the Forties has been produced to explain morphological changes of organisms produce when they experience new environmental conditions or perturbations. Through an important experiment at the base of the so-called concept of genetic assimilation, Conrad H. Waddington showed that a thermic shock can produce changes in wings’ veins of fruit flies, changes that can eventually be inherited across generations, without the environmental trigger that caused them.

This focus on production and (genetic) storage of biological differences elicited by the environment is nowadays coupled with the knowledge produced through microbiome research that explains the phenotypic patterns that recur across generations.

In a thought-provoking twist, with microbiome research, the focus shifts from production and inheritance of biological differences to production and inheritance of biological similarities. Microbiome research shows that some phenotypic patterns are allowed by ecological communities of microorganisms composing all animals. Bacteria allow the development and functioning of our bodies within an epistemic framework that is now key to understand biology. The network of vessels composing mammals’ stomach is formed through cellular differentiation and expression of genes coordinated by bacteria. The same is true for our immune system that is coordinated by gut bacteria. Food, which is an important aspect of our lives also impacts on this microecology and mediates between our biological functions and functioning of means of production whose parts dedicated to food production have immense importance for our biology and our internal and external ecologies. Antibiotic resistance is one of the crossroads where culture, biology, history and the Anthropocene meet. Indeed, Antibiotic resistance shows that means of production of our societies have an even more widespread, deep and allegedly unexpected impact on the biology of animals and plants. The microorganism can indeed adapt to resist the selective toxicity of antibiotics. Moreover, bacteria can transfer their genetic code horizontally, by touch, so that we can acquire antibiotic resistance by eating food that functions as a vector, by hosting lice on our heads and many other contacts. Bacteria that are resistant to antibiotics that have been used as growth factors in animal husbandry and to prevent diseases in livestock and aquaculture, spread in natural ecosystems and can be found in wild species. Rivers and estuarine waters are places hosting antibiotic resistance.

Searching on PubMed (the search engine for biomedical literature) titles of articles containing the terms ‘antimicrobial’ and ‘Louisiana’ I retrieved just one twelve-years-old article. No results with terms such as 'Mississippi' or 'New Orleans'. The authors collected and analysed Oysters from both waters of Louisiana Gulf and in restaurants and food retailers in Baton Rouge. In most of the samples gathered, scientists recognised the presence of bacteria (Vibrio parahaemolyticus and Vibrio vulnificus) resistant to specific antimicrobials. Food production is indeed the first factor in terms of the quantity of antibiotics used. This use and related antibiotic resistance impact all the living beings present in a specific area, and can easily travel around the globe through many channels. As Littman & Viens have highlighted, a sustainable future is a future without antibiotics as “there may be no truly sustainable way of using antibiotics in the long-run, as microorganisms have shown to be almost infinitely adaptable since the first introduction of antibiotics” (Littman & Viens 2015). But in the meanwhile, we need to use them and antibiotic resistance is a phenomenon that can be better studied through environmental research, by analysing wild species and emissions nearby livestock, for instance.

The study that I retrieved focuses on Oysters. But what about antibiotic resistance conveyed through food that is consumed by the most?

What about exposures of communities that are living in highly polluted areas?

And what is the additive value on antibiotic resistance for individuals who experience the presence of industrial pollutants and that live in areas where cancer epidemics are registered?

In this respect, there is a strategy to cope with the issue of antibiotic resistance promoted by the Center for Disease Control and Prevention. The document doesn’t mention any action to monitor and regulate the production and usage of antibiotics in livestock. Nevertheless, the CDC wants to scrutinise, through genome sequencing, “Listeria, Salmonella, Campylobacter, and E. coli and uploads sequence data into PulseNet for nationwide monitoring of outbreaks and trends.” Moreover, the document reports that “In Fiscal Year 2019, Louisiana will begin simultaneously monitoring these isolates for resistance genes. When outbreaks are detected, local CDC-supported epidemiologists investigate the cases to stop spread.”

The questions that I would like to ask (to local ppl, activists, researchers, practitioners..) are:

What could be the epidemiologic characteristics (socioeconomic status, gender, residence..) of the populations more vulnerable to antibiotic resistance?

What is the additive role of antibiotic resistance for people living in highly polluted areas?

What is the impact of antibiotic resistance for people and patients living in areas where cancer incidence is high?

 

And on the long run I am interested in imagining possible strategies to not only living with the problem but also to tackle the problem itself, which means to develop strategies to answer the questions:

Why antibiotic resistance, which is known since a century, it’s a problem on the rise?

What is the role and interest of capitalism, in terms of profit-making of corporations, knowledge production and environmental degradation, in not being able to resolve antibiotic resistance?

What can be strategies of local communities to tackle the problem and to promote environmental justice in terms of alliances with ecologists, doctors, epidemiologists and other activists?

"The 'disaster investigation,' ... actually emerges as a hard-fought contest to define the moment in politics and society, in technology and culture." (page 1).

"[Answers about the World Trade Center] were not reassuring, or especially enlightening answers." (page 16)

"... so many players appeared guildty that none could be singled out for punishment." (page 16)

MSF is focused on providing aid where aid is needed, thus the name "Doctors without Borders." They don't care what the policital or socioeconomic status is in a region, they'll provide aid no matter what. They're also able to provide their own funding rather than relying upon that of local governments.

I looked into each of the disasters mentioned in the article to find out more about them. I had not heard of the theater fire or boiler explosion before, and found those very interesting.

Paul Farmer is the chair of the Department of GLobal Health and Social Medicine at Harvard Medical School. He is an expert in health care services and advocacy for those who are sick and in poverty. He doesn't appear to be situated in emergency response; he seems to be much more on the follow-up months or years later. Dr. Farmer has myriad publications of relevance to the Network, and his research foci are mostly regarding establishing high-quality health care in resource-poor environments.

Bruce Nizeye works as the Chief of Infrastructure for PIH in Rwanda. It appears that his expertise is in physical constructs. I could not find how he was situated in emergency response, but it appears that he takes a role on the back side of disasters, much like Dr. Farmer.

Sara Stulac is an Associate Physician in the Division of Global Health Equity at BWH. She is also the Deputy Chief Medical Director for PIH. She seems to be an expert in pediatrics, specifically HIV care and prevention and oncology. Like her other authors mentioned on this page, she does not seem to be directly involved with emergency response. Her research foci are mostly not related to emergency response, but dealing with non-emergent pediatric care. (http://www.brighamandwomens.org/Departments_and_Services/medicine/servi…)

Salmaan Keshavjee is a professor at HMS and a physician at BWH. He has conducted research on post-Soviet Tajikistan's health transition and worked on an MDR-TB treatment program in Tomsk, Russia. Rather than emergency response, Dr. Keshavjee seems to be focused on epidemiology like his co-authors. He has a number of research foci including MDR-TB treatment and policy, health-sector reform in transnational societies, the role of NGOs in the formation of trans-border civil society, and "modernity, social institutions, civil society, and health in the Middle East and Central Asia.
