The ecology of major human, plant and animal diseases from the Black Plague to the Irish Potato Blight to AIDS. How microbes, people and other organisms interact in a changing environment, leading to new threats and controls for disease. (Gen.Ed. BS)
Hans Zinnser said, “... infectious disease is merely a disagreeable instance of a widely prevalent tendency of all living creatures to save themselves the bother of building the things they require. The plant does the work with its roots and green leaves. The cow eats the plant. Man eats both of them; and bacteria eat the man....” In the process, these interactions have fundamentally shaped our planet and ourselves. Plagues, outbreaks of diseases, have been a part of the human condition since recorded history and undoubtedly long before. In fact, disease is a part of all life for all organisms. At the same time, human activity, from agriculture to jet travel, interact with microbes and the environment to bring about plagues. Often we think of infectious diseases as the microbes that cause disease. A cold, and the virus that cause it, are thought of as the same thing. But infectious disease really describes an ecological interaction between microscopic organisms and other organisms that they use as a source of energy and nutrients, a pathogen and its host. The honors colloquium is an addendum to Microbiol 140P to further explore diseases and how they have shaped our world, how we attempt to manage them, and how we often inadvertently aid and abet them. Microbiol H140 is a 1 credit weekly discussion of readings taken from recent popular literature and press. Students will be asked to summarize the context of these articles, write a critical synopsis and participate in evaluating these synopses for publication in blog-like reader online.

Man has used breeding programs for the last 3000 years to increase yields of plants, to incorporate specific traits into farm animals and pets. Early motivation was probably first survival then commerce. Early tools were based in careful observation. Today, we have biotechnology: the ability to genetically engineer almost any organism. The ability to change and/or create any bio-molecule, drug, antibiotic, fuel or crop is almost at our fingertips. But what will make it happen? What is out motivation: survival in the face of global warming, increasing population, or to increase our own wealth through business? What are the political, social, and ethical implications of what we could do? What is doable, practical, profitable or necessary and what is a pipedream? Satisfies one of three required modules for the Integrative Experience requirement for BA-MicBio or BS-MicBio majors.
Nearly 70% of Americans are obese or overweight. The distribution of the epidemic correlates strongly with poverty and access to high quality food. Students in this class will engage in directed literature research and discussion. Topics will start by examining risks factors for obesity including genetic, macro genetic/microbiome, societal (commercial, race, poverty). The goal of this course is to examine the obesity pandemic using a multidisciplinary approach with the aim of identifying any evidence for effective approaches to changing obesity rates. Satisfies one of three required modules for the Integrative Experience requirement for BA-MicBio or BS-MicBio majors.
HIV rates in U.S. poverty areas rival those found in Haiti, Burundi, Ethiopia, and Angola. HIV prevalence in high-poverty neighborhoods is more than double that of the nation overall. Within high-poverty neighborhoods, prevalence among people living below the poverty line was double that of those living above it. Blacks disproportionately bear the brunt of the HIV epidemic in the US accounting for over 48% of all new cases of the disease while representing only 12% of the population. The HIV epidemic that was once thought to be a declining problem is now threatening to destroy not only the progress previously made, but also the health, well-being and potential of men and women of all races in poverty areas across the United States. Some important questions therefore need to be answered: Is race, poverty or both the driver of HIV in these communities? What should be done to stem the tide of new HIV infections in these areas of our society? This course satisfies one of the three modules required for the Integrative Experience for BA-MicBio and BS-MicBio majors.
Over 70% of the Earth’s surface is covered with the oceans, and nearly all of the life within the
ocean is microscopic. Some of these microbes are photosynthetic and form most of the base of the marine food web. These in turn are consumed by other small creatures that eventually provide food for the larger animals in the sea. Bacteria are responsible for maintaining certain chemical balances in the oceans, and themselves are food for other microbes. Understanding how life is sustained in our oceans is vital for coastal human populations that rely on the sea for food. Other people turn to marine microbes for new biotechnologies, or hope that by understanding them we might understand our own planet’s climate history and how marine microbes will respond to global warming and ocean acidification. Satisfies one of the three required modules for the Integrative Experience requirement for BA-MicBio or BS-MicBio majors.
Students will engage in meaningful literature research and dialogue about whether organic standards are meeting the needs of both environmental and community sustainability. We will also consider the benefits of sustainable agriculture, both in the sense of conservation of land and soil as limiting natural resources, as well as the sense of community with the farm and food production as the center of family and local community life. In exploring these wide-ranging issues, students will have the opportunity to reflect on and integrate their Gen Ed learning experience from various courses as well as practice Gen Ed learning objectives at a more advanced level as they seek meaningful solutions to complex and ever evolving societal problems. Students will work in small groups to explore these solutions allowing them to participate in shared learning experiences as they apply prior knowledge from various Gen Ed courses and social experiences to solve challenging real-world problems. Satisfies one of three required modules of the Integrative Experience requirement for BA-MicBio or BS-MicBio majors.
The vast majority of Earth's biodiversity is microbial. Microorganisms are directly involved in the ecosystem services on which all of life depends. They interact intimately with other organisms and yet we know much less about their biodiversity than we do for plants and animals. Our lack of understanding of the interactions and feedbacks of microbial biodiversity is troubling, given the high rates of environmental change that the Earth is currently experiencing, including man-made global climate change. Satisfies one of three required modules for the Integrative Experience requirement for BA-MicBio or BS-MicBio majors.
Neglected tropical diseases (NTDs) are a set of infectious diseases arising from a diverse group of parasitic worms, bacteria, and vector-borne protozoa that affect an estimated 1.4 billion people worldwide. These diseases affect the world’s most vulnerable populations, almost exclusively poor and powerless people living in rural areas and urban slums of low-income countries. NTDs coexist with poverty because they thrive where access to clean water and sanitation are limited and people live without protection from insects that transmit disease. They also contribute to poverty since they can impair intellectual development in children, reduce school enrollment, and hinder economic productivity by limiting the ability of infected individuals to work. Current control efforts focus primarily on mass drug administration (MDA) to treat the seven most common NTDs and has become one of the most cost effective global health programs to treat multiple diseases at once, in large part because major pharmaceutical companies are donating the needed medicines for free. End 7 is a global campaign to deworm the world and bring an end to 7 of the NTDs. Important questions exist related to this global health strategy: what might be the long-term benefits (and possible detriments) to a sustained global deworming effort? What other measures should be implemented in combination with MDA for sustained control? Satisfies one of the three required modules for the Integrative Experience requirement for BA-MicBio or BS-MicBio majors.
