“Deconstructing the individual: how science can materially advance using queer and feminist theory“
Dr. Patricia Kaishian. Photo courtesy of Dr. Kaishian.
About the speaker: Dr. Patricia Kaishian is a visiting professor of Biology at Bard College in NY. Her scientific research is focused on the taxonomy of Laboulbeniales fungi, fungal biodiversity, and exploration of the use of certain fungi as potential indicators of ecosystem health. Beyond more traditional scientific research, Patricia works in the realms of philosophy of science, feminist bioscience, ecofeminism and queer theory, exploring how mycology and other scientific disciplines are situated in and informed by our sociopolitical landscape. Her publication, The science underground: mycology as a queer discipline, appears in the journal Catalyst: Feminism, Theory & Technoscience. Patricia is also a founding member of the International Congress of Armenian Mycologists (ICAM), a research organization comprised of ethnically Armenian mycologists who seek to simultaneously advance mycological science and Armenian sovereignty and liberation.
This talk will explore the field of mycology and the mycobiome through a theoretical framework rooted in queer and feminist theories, as well as philosophy of science and Traditional Ecological Knowledge. The goal is to challenge, push, and explore central tenets of institutional science, and to socially and historically situate current research dilemmas in mycology and microbiome studies. By excavating and laying bare ingrained, systemic biases in scientific institutions, we can attempt to disarm fallacious assertions of “purity” in science and better understand bodies at various scales.
Undergraduate Animal and Veterinary Science (AVS) students Natalie Sullivan (4th year), Maria Messersmith (3rd year), and Elaina Cobb (3rd year) were awarded a spring 2022 research award from the J. Franklin Witter Undergraduate Research Endowment Fund! Natalie, Maria, and Elaina will be part of a large student researcher team working on different aspects of this project over the next year, but the three of them composed the funding proposal as they have been working on this project the longest.
Background: Cryptosporidiosis, an infection caused by protozoa from the Cryptosporidium genus, often C. parvum, has emerged as a frequently reported intestinal disease of animals and humans since the 1980s when its zoonotic potential was recognized. C. parvum causes a brief diarrheal disease, which can lead to dehydration, weight loss, and, in extreme cases, death, particularly in children or neonatal animals. On farms, the disease results in intense diarrhea of neonatal calves and is associated with substantial economic losses in dairy farming worldwide as it can have long-term effects on weight gain and production efficiency. Cryptosporidiosis is transmissible via the fecal-oral route, either indirectly or directly, and C. parvum is almost always present in water and soil/bedding. There is no treatment, so disease management and prevention tend to be more focused on animal management practices involving nutrition, biosecurity, and cleanliness. This project centers around the tracking of cryptosporidium parvum in different aged dairy cattle populations at the University of Maine’s J.F. Witter Farm.
Soil samples from the farm were checked for the presence of parasites using microscopy.The calf stalls have bedding instead of soil floors, so we need to wash bedding samples to collect any protozoa that might have been left there.Cryptosporidium is most commonly spread through shared water sources so we are monitoring those.Once protozoa have been washed from the samples, the wash is put on glass slides, where dyes are used to stain the cells so we can see them using a microscope.Cows are cute but make sure you wash your hands after touching them to avoid infections.Photos from the Cryptosporidium project.
Importance/Impact: This project will track the trends and prevalence in C. parvum carriage in the Witter herd, and identify if there are certain conditions in which C. parvum is more prone to grow and multiply, especially in dairy calves. We anticipate that any findings will be used to implement new management practices for the control of Cryptosporidium parvum, specifically in bovine management, and reduce zoonosis at this farm. This project will potentially lead to making management recommendations for other farms in Maine.
Research Question, Objectives, and Hypotheses: What are the difference in disease prevalence and contamination between calves, yearlings, and adults in relation to Cryptosporidium parvum? Is infection rate due to risk of age range or animals or housing conditions?

This award will complement the previous funding support we received from the University of Maine Institute of Medicine, and collectively these funds allow us to compensate speakers for their time and effort putting these talks and discussions together.
The series runs every Wednesday at noon from January 19th through May 4th this year, and we have had some incredible presentations and discussions. Registration links for the remaining events, and links to the recordings of previous events, can be found on the series event page.
Series summary: Microbes influence the health and well-being of all living things—individuals, communities, and broader environmental networks which span internationally. The Microbes and Social Equity group is presenting a speaker series, hosted by the University of Maine Institute of Medicine, which will specifically highlight how the different kinds of microbes that we interact with are influenced by aspects of daily life as well as the social policies which support or oppress livelihoods. The virtual speaker series aims to give students, staff, and faculty at UMaine, as well as our broader educational community, the opportunity to learn about how social equity and microbes intersect to shape health in wide range of settings—how we define what a ‘healthy human microbe’ is, how soil microbes shape community health, what challenges the integration of the microbiome research in a One Health perspective, and more. This speaker series will explore the ways that microbes connect public policy, social disparities, and human health, as well as ongoing research, education, policy, and innovation in this field.
I have had the pleasure of sharing my work, both Ishaq lab led and collaborative, to many venues thus far in 2022, and I am grateful to the invitations I received even though I was not able to accept all of them. These have ranged from seminar series, to student groups, to scientific conferences. Some of these events have already passed, but several are forthcoming and available by registration.
